firefoxOk, the title here is pretty long and quite self-explanatory, but that’s the deal! In fact every now and then some Firefox add-ons won’t uninstall through the Uninstall button because the aforementioned button is disabled or doesn’t want to work properly. This issue seems to affect add-ons and themes all the same and most of the times the only solution users have to solve it, is to uninstall Firefox and delete all of its keys in the registry. Anyway, there are other simple fixes and tricks which work and save from a lot of stress. Here is the list:

First Method

When everything seems to be lost, try to uninstall an add-on through the uninstall feature available in Windows Vista. Here is how to reach it:

  1. Click Start.
  2. Click Control Panel.
  3. Click Programs and Features.
  4. Pick  the add-on you want to uninstall and and double click on it.

Second Method

Try to uninstall a stubborn add-on by putting Firefox in safe mode. To turn Safe mode on follow these steps:

  1. Close Firefox.
  2. Click Start.
  3. Open All Programs.
  4. Find Firefox folder and open it.
  5. Click Safe Mode.
  6. Try to uninstal the add-on.
  7. If you want a simpler way to access the Safe Mode click on Start and type in the Search Bar the following command: firefox -safe-mode

Third Method

If the aforementioned methods didn’t work for you, here is another trick which is not very easy to apply but assure you to remove all the unwanted add-ons from your Firefox once for good.

  1. Click Start.
  2. Click Computer.
  3. Click your Local Disk.
  4. Click Programs Files.
  5. Click Mozilla Firefox folder.
  6. Open Extensions folder.
  7. To identify which add-on the folder is representing, go to each folder and perform the following steps: 1) Use a text editor (e.g. Notepad) to open the install.rdf file. 2) Now search the following text: em:name 3) Locate the folder with install.rdf file with the name after the “em:name” corresponding to the extension you intend to remove or delete. 4) Delete the folder of the extension.

    I found these instructions to be most helpful on my hunt to get rid of an extension that had a greyed out uninstall. Our great friends at Microsoft almost made these instructions useless to me until I spotted they do something other than suggested here.

    It was to do with removing the .NET Framework One-click Assistant. I eventually caught up with the evil bastards by looking for “:name” without the quotes to reveal that they do not operate their extensions or add-ons like everyone else does; that abides by the conventions and rules. So to get rid of the wretched .Net Framework thing that doesn’t work anyway do the following:

    Inside the extensions folder indicated in these instructions look for one that simply says extensions.rdf. Then look inside with a search F3 for “:name” and you will be sure to spot ha ha .NET Framework Assistant thingy.

    Hopes this helps the people out there who are still in desperation. Be in desperation no longer and always keep eye out for things that don’t quite look right!
