Nope, tried that, and still SABnzbd opened up in Firefox until I ran sudo dnf remove firefox. No clue why.
As for the randomized mac, OHHHHH thanks! That's probably why when I put that config file there it was confused! I was unaware of this change, thanks again!
And thanks, I'll definitely check out your debloat guide, but I'm still going to have to do some learning and decide for myself because we'll be different. For instance I'm probably keeping kGpg unless I replace it with Kleopatra (ironically also a K haha). I'll definitely use it as a start point though!
