I like Firefox too and I use it. But OP talks about adblocking and disabled pocket by default, so this is why I commented this.
(Actually I don't even use Librewolf, I have just heard of it) EDIT: I saw that OP says that configuration files are an issue, so your comment is okay.
Just use Librewolf. It's a fork of Firefox, with Pocket disabled, Ublock Origin preinstalled, and privacy settings enabled by default.
Oh thank you for your detailed response. I will try some of those YouTube frontends as soon as I can!
I received the same two messages but with an alt account that was actually mine and haven't used in like 2 years. Strange...
Brave is based on Chromium, so the candy doesn't have so nice taste.
