Firefox will not open a new tab

Posted

Firefox has stopped letting me open a new tab. If I click on the plus sign, hit Ctrl-T, or go to File>New Tab, nothing happens. The only way a new tab will open is if I click on a link in an email, then it opens the link as a new tab. I use tabs frequently and it's very annoying to have to go find an email with a link just so I can open a tab. It doesn't matter if I have only one or several tabs open. I haven't installed anything other than Firefox and Windows (I have Windows 7) updates. I am running Firefox 24.0 but the problem started with the earlier version.

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

  • 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.
