Uninstall Or Delete Firefox Add-ons Manually When Uninstall Button In Add-ons Window Is Disabled
In Firefox browser, it is not always possible to uninstall or remove the add-ons such as toolbars, extensions, themes etc. through the Add-ons Window. At times, the button “uninstall” in the Add-ons Window corresponding to some add-ons is disabled and appears to be grayed out.
However in such cases, you need to use a separate workaround to manually uninstall such ‘stubborn’ add-ons like toolbars, extensions or themes. Below mentioned are a few techniques that help you in uninstalling, deleting or removing Firefox Add-ons.
Technique 1: Uninstall the Add-ons using the option “Uninstall a Program” or “Add/ Remove Programs”
Some application programs tend to install their respective extensions or add-ons and such add-ons need to be removed or uninstalled using the relevant setup uninstaller. Typically, for uninstalling a program you need to go to the Control Panel and select the option “Uninstall a program” (In Windows Vista) or “Add/ Remove Programs” (In Windows XP).
However, you need to remember to close Mozilla Firefox browser before starting with the un-installation process.
Technique 2: Uninstall the Add-ons in Firefox Safe Mode
Incase an extension, theme or toolbar does not offer an uninstaller or if you find that the button “uninstall” corresponding to a particular add-on is grayed out or disabled, you might try unintalling it in Firefox Safe Mode.
In order to access the Firefox Safe Mode, follow the below mentioned steps:
- You need to first exit all Firefox Windows.
- Click on the “Start” button to display the Start Menu. Go to “All Programs” list. Navigate to the folder “Mozilla Firefox” and select Firefox (Safe Mode). As another option to get to Firefox Safe Mode, you may go to the option “Run” (“Start Search” incase of Windows Vista) and type in “firefox -safe-mode” and press “Enter”.
Incase of Mac OS X having Firefox 3, you need to hold down Options key while launching Firefox in order to open Firefox in Safe Mode.
Incase of Mac OS X having Firefox 2, open the folder “Applications”, go to “Utilities” directory and open “Terminal”. Run the command mentioned below:
For E.g. “/Applications/Firefox.app/Contents/MacOS/firefox -safe-mode”
- Firefox will now start in safe Mode with a dialog “Firefox Safe Mode”. Now that Firefox is operating in Safe Mode, “uninstall” buttons corresponding to some add-ons which were previously grayed out or disabled in the Add-ons window will now be enabled for uninstalling the add-ons properly.
Technique 3: Uninstall User-specific Add-ons (toolbars, extensions, themes etc.) Manually
If you are unable to uninstall add-ons using the above mentioned methods, you can uninstall user-centric add-ons using the below mentioned process:
- Go to the folder “Profiles” which you can generally find at the location “%AppData%\Mozilla\Firefox\Profiles\xxxxxxxx.default\”. Here, xxxxxx corresponds to a random string. You need to choose active profile folders i.e. the profile folders that contain multiple sub-folders.
- Open the folder “Extensions” present within the profile folder.
- Each folder that is present within the folder “Extensions” resembles an extension. A few folders might have readable names which correspond to the plug-in, toolbar or extension and can be identified quite easily. You will find the names of some folders to be obscured. In order to recognize the extension that the folder represents, you need to open each folder and follow the below mentioned steps.
- Use any text editor (Eg. Notepad) to open the file “install.rdf” present within the folder.
- Check for the text “em:name” inside the file “install.rdf”
- Find the folder having the file “install.rdf” in which the name following the text “em:name” resembles the extension that you intend to delete or remove.
- Now delete the entire folder for that particular extension.
Technique 4: Uninstall Globally Installed Extensions Manually
It is not possible for you to delete or remove globally installed extensions using the Add-ons window. You need to use the below mentioned procedure to remove such globally installed extensions.
- Open Firefox installation folder which is generally located at “C:\Program Files\Mozilla Firefox”.
- Within the installation folder, go to the folder “Extensions”.
- Each folder that is present within the folder “Extensions” resembles an extension. A few folders might have readable names which correspond to the plug-in, toolbar or extension and can be identified quite easily. If the names of some folders are obscured, you need to open each folder and follow the below mentioned steps to recognize the extension that it represents.
- Open the file “install.rdf” present within the folder in a text editor (E.g. Notepad).
- Look for the text “em:name” inside the file “install.rdf”.
- Find the folder that has the file “install.rdf” in which the name following the text “em:name” resembles the extension that you intend to delete or remove.
- Simply delete the entire folder for that particular extension.
