Browser plugins (Русский)
Есть два типа плагинов для браузеров, в зависимости от API, на котором они основаны:
- Netscape plugin API (NPAPI): эти плагины работают в Firefox, Opera и большинстве других браузеров (не в Chromium).
- Pepper plugin API (PPAPI): эти плагины работают только в Chromium и Chrome.
Most plugins on this page are NPAPI-only, unless noted otherwise.

Flash Player
Shumway
Shumway is an HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF file format without native code assistance. As of 2013-01-01, the plugin may be installed directly from Mozilla's github.io site. According to the Shumway wiki, "Integration with Firefox is a possibility if the experiment proves successful."
Shumway is also embedded in Firefox Nightly/Aurora builds.
Gnash
See also Wikipedia:Gnash.
GNU Gnash is a free (libre) alternative to Adobe Flash Player. It is available both as a standalone player for desktop computers and embedded devices, as well as a browser plugin, and supports the SWF format up to version 7 (with versions 8 and 9 under development) and about 80% of ActionScript 2.0.
There are multiple packages available: gnashAUR[ссылка недействительна: сохранено в aur-mirror], gnash-kde4AUR[ссылка недействительна: сохранено в aur-mirror], gnash-gitAUR.
Lightspark
Lightspark is another attempt to provide a free alternative to Adobe Flash aimed at supporting newer Flash formats. Lightspark has the ability to fall back on Gnash for old content, which enables users to install both and enjoy wider coverage. Although it is still very much in development, it supports some popular sites.
Lightspark can be установлен with the package lightsparkAUR[ссылка недействительна: сохранено в aur-mirror] or lightspark-gitAUR.
Adobe Flash Player
Установка
Пакет, который нужно установить зависит от браузера, которым вы пользуетесь.
- Версию NPAPI можно установить с помощью пакета flashplugin из официальных репозиториев. Этот плагин больше не поддерживается Adobe и остановился на версии 11.2; однако Adobe будет предоставлять обносления безопасности в течение 5 лет (т.е. до 2017).
- Версия PPAPI распространяется вместе с Google Chrome. Если вы используете Chromium или какой-либо другой браузер, использующий интерфейс PPAPI, то смотрите Chromium#Flash Player plugin для дополнительной информации.
Configuration
To change the preferences (privacy settings, resource usage, etc.) of Flash Player, right click on any embedded Flash content and choose Settings from the menu, or go to the Adobe website. There, a Flash animation will give you access to your local settings.
You can also use the Flash settings file /etc/adobe/mms.cfg
.
To enable VDPAU, uncomment the following line:
EnableLinuxHWVideoDecode=1
A more detailed example configuration:
/etc/adobe/mms.cfg
AVHardwareDisable = 0 FullScreenDisable = 0 LocalFileReadDisable = 1 FileDownloadDisable = 1 FileUploadDisable = 1 LocalStorageLimit = 1 ThirdPartyStorage = 1 AssetCacheSize = 10 AutoUpdateDisable = 1 LegacyDomainMatching = 0 LocalFileLegacyAction = 0 AllowUserLocalTrust = 0 # DisableSockets = 1 OverrideGPUValidation = 1 DisableDeviceFontEnumeration = 1 #Prevent sites to identify you by snooping the installed fonts
You can also refer to the mms.cfg from Gentoo, which is extensively commented.
Disable the "Press ESC to exit full screen mode" message

Copy the patched Flash Player back to the plugins directory:
# cp ~/libflashplayer.so /usr/lib/mozilla/plugins/
Multiple monitor full-screen fix
- This only works for the NPAPI plugin.
- There is also a package flashplugin-focusfixAUR in the AUR that includes this fix.
- sourced from this post on webupd8
When using a multiple monitor setup, or swapping between virtual desktops, it is possible to lose focus on a fullscreen flash window. In such a case, the adobe flash-plugin will automatically exit full-screen mode. This may not be to your liking.
Unfortunately, this behavior is hard coded into the binary. In order to change this behavior it is necessary to alter the binary.
First you will need a hex editor, such as ghex.
Then, you will need to alter the adobe flash-plugin binary, which is commonly located at /lib/mozilla/plugins/libflashplayer.so
. It is prudent of course to first backup the file, in case you want to revert the behavior or make a mistake while editing.
# cp /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/mozilla/plugins/libflashplayer.so.backup
Then open the binary in the hex editor with root privileges:
# ghex /usr/lib/mozilla/plugins/libflashplayer.so
Using the hex editor find the string _NET_ACTIVE_WINDOW
. In ghex the readable string is on the right hand side of the window, and the hex is on the left, you are trying to locate the readable string. It should be easy to find using a search function.
Upon finding _NET_ACTIVE_WINDOW
rewrite the line, but do not change the length of the line, for example _NET_ACTIVE_WINDOW
becomes _XET_ACTIVE_WINDOW
.
Save the binary, and restart any processes using the plugin (as this will crash any instance of the plugin in use.)
Fullscreen fix for GNOME 3
If you have problems with Flash's fullscreen-mode (video freezes but audio keeps playing), then it is probably because the fullscreen flash window is displayed behind the browser window. This is a known upstream bug in mutter. You can easily fix this by using devilspie:
Install devilspie from the official repositories.
Create the ~/.devilspie
directory:
# mkdir ~/.devilspie
Now you have to create a config file for each browser you use (see below)
Finally, add devilspie to your list of startup items by adding the following file to ~/.config/autostart
~/.config/autostart/devilspie.desktop
[Desktop Entry] Name=devilspie Exec=devilspie Hidden=false NoDisplay=false X-GNOME-Autostart-enabled=true
Firefox
~/.devilspie/flash-fullscreen-firefox.ds
(if (is (application_name) "plugin-container") (begin (focus) ) )
Chrome / Chromium
~/.devilspie/flash-fullscreen-chrome.ds
(if (is (application_name) "exe") (begin (focus) ) )
Epiphany / GNOME Web
~/.devilspie/flash-fullscreen-epiphany.ds
(if (is (application_name) "WebKitPluginProcess") (begin (focus) ) )
Video players workarounds
Open-with Firefox extension
- Install Open-with add-on.
- Open
about:openwith
, select Add... - In the dialog select a video streaming capable player (e.g. /usr/bin/mpv).
- (Optional step) Add needed arguments to the player (e.g. you may want
--force-window --ytdl
for mpv) - (Optional step) Choose how to display the dialogs using the left panel.
- Right click on links or visit pages containing videos. If the site is supported, the player will open as expected.
The same procedure can be used to associate video downloaders such as youtube-dl.
PDF viewer
PDF.js
PDF.js is a PDF renderer created by Mozilla and built using HTML5 technologies.
For Firefox it is available as a plugin, which is included in Firefox since version 19.
For Chromium and Google Chrome there is an experimental extension in the Chrome web store or alternatively it can be built from the source of Pdf.js.
External PDF viewers
To use an external PDF viewer you need #MozPlugger or #kpartsplugin.
If you want to use MozPlugger with Evince, for example, you have to find the lines containing pdf
in the /etc/mozpluggerrc
file and modify the corresponding line after GV()
as below:
repeat noisy swallow(evince) fill: evince "$file"
(replace evince
with something else if it is not your viewer of choice).
If this is not enough, you may need to change 2 values in about:config
:
- Change
pdfjs.disabled
's value to true; - Change
plugin.disable_full_page_plugin_for_types
's value to an empty value.
Restart and it should work like a charm!
Adobe Reader
Due to licensing restrictions, Adobe Reader cannot be distributed from any of the official Arch Linux repositories. There are versions available in the AUR. Please note that no matter how many votes it receives, Adobe Reader will never be included in the official repositories.
Also, there are localizations available in many languages.
32-bit
Adobe Acrobat Reader is only available as a 32-bit binary. It can be installed with the acroreadAUR package, available in the AUR.
This package installs the Acrobat Reader application as well as the Firefox plugin. Note that hardware-assisted rendering is unavailable under Linux (at least using a Geforce 8600GTS with driver version 185.18.14).
64-bit
There is yet to be an official 64-bit version of Adobe Reader.
To use it in a 64-bit environment, you can:
- Follow this guide originally posted in the forums. It involves creating a chrooted environment that could be reused for other 32-bit only applications.
- Install acroreadAUR (with all its 32-bit dependencies) from AUR. Be advised that the Firefox plugin cannot be used directly with this binary -- it will not load in the 64-bit browser. To load it install the nspluginwrapper package from the official [multilib] repository and run:
$ nspluginwrapper -v -a -i
as a normal user. This checks the plugin directory and links the plugins as needed.
Citrix
See Citrix.
Java (IcedTea)
To enable Java support in your browser, you have two options: the open-source OpenJDK (recommended) or Oracle's proprietary version. For details about why OpenJDK is recommended see this.
To use OpenJDK, you have to install the IcedTea browser plugin, icedtea-web.
If you want to use Oracle's JRE, install the jreAUR (or jre6AUR) package, available in the AUR.
See Java#OpenJDK for additional details and references.
Pipelight
See Pipelight.
Multimedia playback
Many browsers support the GStreamer framework to play multimedia inside HTML5 <audio>
and <video>
elements. Check the optional dependencies of the browser package (or webkitgtkAUR/webkitgtk2AUR if using a webkit-based browser) to see which version of GStreamer is supported: this can be either gst-*
for the current version, or gstreamer0.10-*
for the legacy version. See GStreamer#Installation for the description of each plugin.

MozPlugger
MozPlugger can be installed with the mozpluggerAUR package.
MozPlugger is a Mozilla plugin which can show many types of multimedia inside your browser. To accomplish this, it uses external programs such as MPlayer, xine, Evince, OpenOffice, TiMidity, etc. To modify or add applications to be used by MozPlugger just modify the /etc/mozpluggerrc
file.
For example, MozPlugger uses OpenOffice by default to open doc
files. To change it to use LibreOffice instead, look for the OpenOffice section:
/etc/mozpluggerrc
... ### OpenOffice define([OO],[swallow(VCLSalFrame) fill: ooffice2.0 -nologo -norestore -view $1 "$file" swallow(VCLSalFrame) fill: ooffice -nologo -norestore -view $1 "$file" swallow(VCLSalFrame) fill: soffice -nologo $1 "$file"]) ...
and add LibreOffice at the beginning of the list:
/etc/mozpluggerrc
... ### LibreOffice/OpenOffice define([OO],[swallow(VCLSalFrame) fill: libreoffice --nologo --norestore --view $1 "$file" swallow(VCLSalFrame) fill: ooffice2.0 -nologo -norestore -view $1 "$file" swallow(VCLSalFrame) fill: ooffice -nologo -norestore -view $1 "$file" swallow(VCLSalFrame) fill: soffice -nologo $1 "$file"]) ...
doc
files.As another simple example, if you want to open cpp
files with your favorite text editor (we will use Kate) to get syntax highlighting, just add a new section to your mozpluggerrc
file:
/etc/mozpluggerrc
text/x-c++:cpp:C++ Source File text/x-c++:hpp:C++ Header File repeat noisy swallow(kate) fill: kate -b "$file"
To change the default of MPlayer so that mpv is used instead, change the appropriate lines such that:
/etc/mozpluggerrc
... ### MPlayer #define(MP_CMD,[mplayer -really-quiet -nojoystick -nofs -zoom -vo xv,x11 -ao esd,alsa,oss,arts,null -osdlevel 0 $1 </dev/null]) define(MP_CMD,[mpv -really-quiet $1 </dev/null]) #define(MP_EMBED,[embed noisy ignore_errors: MP_CMD(-xy $width -wid $window $1)]) define(MP_EMBED,[embed noisy ignore_errors: MP_CMD(--autofit=$width -wid $window $1)]) #define(MP_NOEMBED,[noembed noisy ignore_errors maxaspect swallow(MPlayer): MP_CMD($1)]) define(MP_NOEMBED,[noembed noisy ignore_errors maxaspect swallow(mpv): MP_CMD($1)]) ... #define(MP_AUDIO,[mplayer -quiet -nojoystick $1 </dev/null]) define(MP_AUDIO,[mpv -really-quiet $1 </dev/null]) #define(MP_AUDIO_STREAM,[controls stream noisy ignore_errors: mplayer -quiet -nojoystick $1 "$file" </dev/null]) define(MP_AUDIO_STREAM,[controls stream noisy ignore_errors: mpv -really-quiet $1 "$file" </dev/null]) ...
For a more complete list of MozPlugger options see this page.
kpartsplugin
The KParts plugin is a plugin that uses KDE's KPart technology to embed different file viewers in the browser, such as Okular (for PDF), Ark (for different archives), Calligra Words (for ODF), etc. It cannot use applications that are not based on the KPart technology.
The KParts plugin can be installed with the package kpartsplugin[ссылка недействительна: сохранено в aur-mirror], available in the official repositories.
Troubleshooting
Flash Player: no sound
Flash Player outputs its sound only through the default ALSA device, which is number 0. If you have multiple sound devices (a very common example is having a sound card and HDMI output in the video card), then your preferred device may have a different number.
For a list of available devices with their respective numbers, run:
$ aplay -l
**** List of PLAYBACK Hardware Devices **** card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: DX [Xonar DX], device 0: Multichannel [Multichannel] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: DX [Xonar DX], device 1: Digital [Digital] Subdevices: 1/1 Subdevice #0: subdevice #0
In this case, the HDMI output is card 0
and the sound card is card 1
. To make your sound card the default for ALSA, create the file .asoundrc
in your home directory, with the following content:
~/.asoundrc
pcm.!default { type hw card 1 } ctl.!default { type hw card 1 }
Flash Player: blocking sound for other applications or delayed playback
If sound is delayed within Flash videos or Flash stops sound from any other application, then make sure you do not have snd_pcm_oss
module loaded:
$ lsmod | grep snd_pcm_oss
You can unload it:
# rmmod snd_pcm_oss
and restart the browser to see if it helps.
Flash Player: performance
Adobe's Flash plugin has some serious performance issues, especially when CPU frequency scaling is used. There seems to be a policy not to use the whole CPU workload, so the frequency scaling governor does not clock the CPU any higher. To work around this issue, see CPU frequency scaling#Switching threshold
Flash Player: low webcam resolution
If your webcam has low resolution in Flash (the image looks very pixelated) you can try starting your browser with this:
$ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so [broswer]
Flash Player: black bars in full screen playback on multi-headed setups
The Flash plugin has a known bug where the full screen mode does not really work when you have a multi-monitor setup. Apparently, it incorrectly determines the full screen resolution, so the full screen Flash Player fills the correct monitor but gets scaled as if the monitor had the resolution of the total display area.
To fix this, you can use the "hack" described here. Simply download the source from the link given on the page, and follow the instructions in the README.
Flash Player: blue tint on videos with NVIDIA
An issue with flashplugin versions 11.2.202.228-1 and 11.2.202.233-1 causes it to send the U/V panes in the incorrect order resulting in a blue tint on certain videos. Version 0.5 of libvdpau includes a workaround to fix this, see the official announcement.
Flash Player: leaking overlay with NVIDIA
This bug is due to the incorrect color key being used by the flashplugin version 11.2.202.228-1 (see this post on the NVIDIA forums) and causes the Flash content to "leak" into other pages or solid black backgrounds. To avoid this issue simply export VDPAU_NVIDIA_NO_OVERLAY=1
within either your shell profile (e.g. ~/.bash_profile
or ~/.zprofile
) or ~/.xinitrc
Flash Player: videos not working on older systems
If you have Adobe Flash installed on an older system and you start playing a video which simply turns black with nothing happening, it is most likely that your CPU does not support SSE2. You can simply check this by looking at your CPU flags with this command:
$ grep sse2 /proc/cpuinfo
If no results are returned, then you need to install an older version of Flash (for example 10.3, or 11.1). Older versions possibly will have vulnerabilities. You should then consider sandboxing Firefox using sandfoxAUR. See the sandfox homepage for usage information.
Older versions of Flash are available here:
https://www.adobe.com/products/flashplayer/distribution3.html
You need to copy libflashplayer.so
to the folder /usr/lib/mozilla/plugins/
Older flashplugin packages can be downloaded from the AUR e.g. flashplugin-10AUR[ссылка недействительна: сохранено в aur-mirror].
The most recent package without SSE2 is flashplugin-11.1.102.63-1-i686.pkg.tar.xz
. If you use the packaged version, you have to add IgnorePkg = flashplugin
to /etc/pacman.conf
.
Plugins are installed but not working
A common problem is that the plugin path is unset. This typically occurs on a new install, when the user has not re-logged in before running Firefox after the installation. Test if the path is unset:
echo $MOZ_PLUGIN_PATH
If unset, then either re-login, or source /etc/profile.d/mozilla-common.sh
and start Firefox from the same shell:
source /etc/profile.d/mozilla-common.sh && firefox
Gecko Media Player will not play Apple trailers
If Apple Trailers appear to start to play and then fail, try setting the user agent for your browser to:
QuickTime/7.6.2 (qtver=7.6.2;os=Windows NT 5.1Service Pack 3)
