How to Turn Flash off in Firefox
The Flash plugin provides Firefox with a way to display animated interfaces, video players, games and other multimedia content on websites. Some users may want to disable the plugin, however, to speed up their computers or avoid flash-based advertisements. Disabling Flash also provides an easy way to keep students or employees from playing games or watching movies on school and office computers. Firefox provides an internal method to temporarily disable Flash, or you can uninstall it permanently from Windows.
Open the "Tools" menu in Firefox and click "Add-ons." If you don't see the "Tools" menu, click the "Firefox" button instead and then click "Add-ons."
Click the "Plugins" tab on the "Add-ons" window.
Find and click the entry for Flash, usually listed as either "Shockwave Flash" or "Adobe Flash," followed by a version number.
Press the "Disable" button.
Quit Firefox to save the setting. Reopen Firefox and confirm no Flash content plays.
Quit Firefox and any other open Web browsers.
Open the Windows "Start" menu and click "Control Panel."
Click "Programs," then "Programs & Features." Depending on your view settings, "Programs & Features" may appear directly on the first control panel window without needing to click "Programs."
Find every listing beginning "Adobe Flash Player."
Click one Flash listing and press "Uninstall." Follow the on-screen directions to complete the removal.
Repeat with any other listings to uninstall all Flash-related programs.
Close the control panel windows and launch Firefox to confirm Flash content does not run.
Tips & Warnings
- Return to the "Plugins" tab of the "Add-ons" window and press "Enable" on Flash to undo the temporary process and use Flash again.
- To restore Flash after a full uninstall, visit the Adobe Flash website and download the plugin again.
- Disabling Flash may have unintended consequences. Many websites use Flash to display basic page elements, such as menu bars. Without Flash, these sites won't run properly.
