Tabs won't close.


For the past few days I have been unable to close tabs. Clicking the "X" in the right corner of the tab does nothing. I can open new tabs though. It's really annoying. And yes I've restarted it and all that crap.

This happened

A few times a week

This started when...

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.


If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

  • Use "Disable all add-ons" on the Troubleshoot Firefox issues using Safe Mode start window to disable all extensions.
  • Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

I had this. Found the problem for me was the AddOn "ImageTweak" version 0.22 - I'm running Firefox 3.6.18

I tried all of this and it didn't work. Someone else posted a solution that worked for me. check your Home page dialog box- I had multiple URLs listed in there, so each time I started Firefox, it would load all of them. It also explained why each time I clicked the Home button, it would reload all of the tabs again. I just cleared the field in the dialog box, put in one address and voila!
