Ever since the latest update, when I hit 'file' and try to 'add tab' it does not work. I have to open another window. I am not a techie, but familiar with IT to some extent. Is the the problem you have been talking about regarding the add-on :tab mix plus'? Please help. thanks.

Try the Firefox SafeMode to see how it works there.
A troubleshooting mode, which disables most Add-ons.
Troubleshoot Firefox issues using Firefox SafeMode

When in Safe Mode...

  • The status of plug-ins is not affected.
  • Custom preferences are not affected.
  • All extensions are disabled.
  • The default theme is used, without a persona.
  • userChrome.css and userContent.css are ignored.
  • The default toolbar layout is used.
  • The JIT Javascript compiler is disabled.
  • Hardware acceleration is disabled.


  • You can open the Firefox 15.0+ SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
  • Or use the Help menu item, click on Restart with Add-ons Disabled... while Firefox is running.


To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.


If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.

Question owner

I am so excited---it worked! I went in and there was a dictionary.com extension dated today 12/10/12. I didn't do anything today with dictionary.com, so I deleted the extension, re-started Mozilla, and VOILA! Thank you so much! I feel so good that I got this figured out, and I do so appreciate your help. I am very grateful and happy!!!
