I always use F11 to expand the screen for full coverage and it don't work on Firefox. What am I missing or how can I get it to open for full frame on the monitor?

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.
