opening Firefox Extension Manager

Recently, I tried to install the new Google toolbar into Firefox (1.06, in Win XP), and it wouldn’t install. I found out that I could no longer open the Extension Manager (via Tools > Extensions) either – the command looked like it activated, cursor turned into an hourglass for a moment, but no Extensions window.

The first solution I found at MozillaZine, Extensions does not install, looked too complicated. Extension Manager Enhancement didn’t help either. I did not want to start a new profile, nor work with installation and config files.

I found the solution to my particular problem at MozillaZine: Safe Mode. I first had to make sure Firefox was not running in background by going to Task Manager and ending the firefox.exe process. Then I ran Firefox in Safe Mode, and was able to open the Extension Manager (!) and by process of elimination delete the incompatible extension. Voila, back in business!

I had searched using keywords like “couldn’t open Extension window”, “Extensions won’t install”, “cannot open Firefox extensions”, “Firefox extension manager won’t open”. I mention them here for others who’d like to solve a similar issue.

    Oh thank you so much! I was having this problem after trying to uninstall Adblock, and I was getting very frustrated until I found your post. Your solution worked perfectly. Thanks again!

    Same problem with Adblock trying to get it to work with flash??? At any rate the fix was the same, safe mode.
