Why won't Firefox open a second tab after upgrading to version 30?

Posted

I run Windows 7 Pro. Up until the latest auto update I could clcik the plus sign on the tab and open new tabs. Won't work now. Please advise.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.
