Version 30 on Mac OS X Mavericks no longer creates >1 tab

After upgrading from v29 to 30, I find that pressing Command-T no longer creates another tab window. Nor does the FIle -> New Tab menu option. The only way to get multiple windows now is to press Command-N or use the File menu.

The hardware in use is an iMac, if that at all matters...

In case one of your extensions is involved, could you test the page in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using either:

  • "3-bar" menu button > "?" button > Restart with Add-ons Disabled
  • Help menu > Restart with Add-ons Disabled

Not all add-ons are disabled: Flash and other plugins still run

After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (not Reset).

Any difference?
