I cannot open a new window even when i have the option "Open new window in tab" checked.

Firefox will NOT open a new window under any circumstances. Also, when I quit Firefox, the system thinks that multiple instances of FF is running but they are invisible to me.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.
