The grey bar at the top of Firefox is too thick. How do I reduce this to give me more room to see the web page?

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).


Do you see unknown toolbar in View > Toolbars that may accommodate for that gray space?


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