Hello!

I would be very grateful if you could help me figure it out, the browser suddenly stopped working, does not open any tabs, just a blank screen, does not open settings, some buttons simply do not respond at all. I cleaned the SScleaner yesterday, but I did not select anything special there, it was a basic regular cleaning that the program offers.

How do I fix this? reinstalling does not help, the browser still does not work

Does that also happen with a clean [new profile](https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles)? If not, you could switch back to your broken profile and [refresh](https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings) FF there. That will save you some time restoring things.
