Having problems with websites that use plugins like Adobe Flash? You'll need to check whether or not the plugin is the cause. We'll explain how to do this.
Contenu:
If you are having problems with pages that use [[Use plugins to play audio, video, games and more|plugins]] (such as Flash, Windows Media Player, Java, and more) to display content, you may need to check to see whether a plugin is causing the problem.
Common problems caused by plugins include:
* [[Firefox crashes - Troubleshoot, prevent and get help fixing crashes|Crashing]] or [[Firefox hangs or is not responding - How to fix|Hanging]]
* [[Fix problems that cause images to not show|Images]] or [[Fix common audio and video issues|multimedia]] items do not load
* [[What to do if you can't download or save files|Problems downloading]]
This article describes how to troubleshoot plugins. If you are having a problem with an extension or theme, see [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]. For general information on plugins, see [[Use plugins to play audio, video, games and more]].
__TOC__
= Determining if a plugin is the problem =
You can selectively disable plugins while Firefox is running. If you suspect a certain plugin, disable it first, then test for your problem. If you don't know which plugin to disable:
#[[T:Open Add-ons|type=Plugins]]
# Select a plugin in the list and then click its {button Disable} button. Repeat this step for each plugin in the list. You do not need to restart Firefox for the changes to take effect.
# Test for your problem. If it does not occur, go back to the Add-ons Manager tab and re-enable plugins one-by-one with the {button Enable} button until you find which one causes your problem to occur.
If you find that disabling a plugin fixes your problem, continue following the steps in this article.
= Updating or re-installing your plugins =
Many problems with plugins can be solved by updating to the latest version of the plugin. [[T:plugincheck]]
If updating to the newest version of the plugin or reinstalling it does not fix the problem, you can leave it disabled.
= Manually uninstalling a plugin =
If you can't use an uninstaller program to remove a plugin, you can remove it manually:
# [[T:aboutconfig]]
# Search for the preference: {pref plugin.expose_full_path}.
# Double-click on the {pref plugin.expose_full_path} preference in the list to change the value to {pref true}.
# Enter '''about:plugins''' into the Location bar to display the About Plugins page.
# Each entry in the About Plugins page will have "File name:" followed by a path. {for win}Use Windows Explorer to navigate{/for}{for mac,linux}Navigate{/for} to the folder shown for the plugin you want to remove.
# Rename the file to something other than its normal name - e.g. {filepath npswf32} becomes {filepath Xnpswf32}
# Double-click on the {pref plugin.expose_full_path} preference in the list on the about:config page to change the value back to {pref false} to avoid exposing the plugin path to websites.
The plugin will be removed.
= Re-initializing the plugins database =
In some cases, you may not be able to install or re-install a plugin. Re-initializing the plugins database may fix this problem:
# [[T:profileFolder]]
# [[T:closeFirefox]]
# Delete the {filepath pluginreg.dat} file.
# Open Firefox
# In the Location bar type '''about:plugins''' and press {for win,linux}{key Enter}{/for}{for mac}{key Return}{/for} to bring up the Firefox plugins list.

= Manually uninstalling a plugin =
In Firefox 21, there is no way to display the full file path in the about:plugins list so, you can inspect the contents of the "pluginreg.dat" file in [https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data profile folder] to find the location for each plugin.
You can open "pluginreg.dat" with a text editor, to view the contents.
{/for}
{for fx22, fx23}
= Manually uninstalling a plugin =
Starting in version 22 (e.g., Firefox 22) an extra row "Path:" is included in the about:plugins list, which displays the full file path for all plugins.
Each entry in the About Plugins page will have "File name:" followed by a path.
Enter about:plugins into the [https://support.mozilla.org/en-US/kb/awesome-bar-find-your-bookmarks-history-and-tabs Location bar] to display the About Plugins page. Now the full file path on each entry it is watchable and you can find easily the location of the plugin you want to remove.
