Cannot open new tabs

Or the shortcut I have always used (command-tab) or even by clicking on '+' on the title bar worked, for the past few weeks. The only way I can get a new tab to open is by clicking on the links. I checked and updated, I know how to create new keyboard shortcuts... I just can't understand why normal methods don't work anymore. I have no problem with other browsers. Any ideas?

We have seen reports on an extension of community toolbar causing this problem of not being able to open a new tab.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

  • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
  • Do NOT click on the reset button on the startup window Mode safe
