Hi! Go to Edit-->Preferences-->Tab And check "Open in a new tab insthead"

If you can see the MenuBar for "Edit", right click on Menu area and select "Menu toolbar" .

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 or otherwise make changes.

The edit menu is different for every OS:

  • Windows: Tools -> Options...
  • Linux: Edit -> Preferences
  • MacOS: Firefox -> Preferences...
