Is Gorhill still around? I wonder if he has ever heard about such a weird corruption of uBlock? I still wonder how to fix it, I copied the profile folder of another Vivaldi installation and I somehow did manage to get a working uBlock extension. The problem is, all other extensions were erased and thus somehow not copied. And bookmark and browser settings were also erased, and I realy don't feel like having to reinstall Vivaldi from scratch. In other words, I need to know which folder I need to copy or doesn't it work like this? Isn't uBlock installed in a specific folder?
