I ran the windows 11 system file checker (sfc/scannow) to fix a font problem I was having. It did say that problems were found and fixed and I do not seem to have that problem any more. After that, i could not access the Settings in Firefox. I uninstalled and reinstalled Firefox and still could not access Settings. I also cannot access any Web sites either by typing them into the address bar or using bookmarks. Both Chrome and MS Edge work.

I queried Copilot and it suggested starting FF in safe mode which worked in bring up a usable FF. I then change the proxy setting to no proxy and that fixed my problem.

Did you try reinstalling FF?

I have uninstalled and reinstalled FF twice. When I select any menu item that would show up in a web page, nothing happens. When I enter a Web address, the address bar is cleared and the screen shows just a blank page. The uninstall process leaves remnants of the previous install so they are not truly new installs. Is there a way to do a complete uninstall so that the install file sees a machine that never had FF installed. Before I do that how do I back up my bookmarks so that I can restore them after the install?
