Reviews of ublock origin:

It stopped working for a while and i uninstalled it. I tried other apps because it broke a website that I watch soap operas from regularly . I just randomly decided to install it again and it worked flawlessly! No need for even adding filters like I used to .

Its been very stable and helpful up till recently, where it just randomly starts disabling itself. Is there a fix for this?
