I'm able to open sites from my toolbar but the "+" at teh top of the Mozilla homepage doesn't work. I cannot open another window to go to another site by using the "+" at the top of the page. If I try to open another site frm my toolbar, it replaces the current page.

We have recently seen reports about a Community Toolbar extension causing this issue with not being able to open a new tab.

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
