If you are having problems with pages that use [[Using plugins with Firefox|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|Crashing]] or [[Firefox hangs|Hanging]] * [[Images or animations do not show|Images]] or [[Video or audio does not play|multimedia]] items do not load * [[Unable to 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 [[Troubleshooting extensions and themes]]. For general information on plugins, see [[Using plugins with Firefox]]. __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 {for fx4}Manager tab{/for}{for fx3,fx35}window{/for} 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.
