Why won't it let me close a tab?
I currently have 4 tabs up. I've tried keyboard controls, clicking the x on right had corner of the one I want to close, and right clicking the tab and choosing the close tab option. The only way I can close tabs is to exit firefox which is counterproductive if there's one tab I need to keep open. I've gone through the tools & options as well as your trouble shooting info, but no answer.

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

Set the browser.tabs.closeWindowWithLastTab pref to false on the about:config page to prevent closing the last tab from closing that window and make a close button appear if only one tab is open.
