Describe the issue

uBlock was automatically updated to 1.13.10, and since then it stopped working whatsoever (can't even get access to the options screen), and the icon disappeared (from next to the address bar).

uBlock is still listed as enabled on Extensions and I can see [More] page, beyond that nothing works.

One or more specific URLs where the issue occurs

All, not working at all I get ads in every website.

Steps for anyone to reproduce the issue
