I’m on Linux with Firefox and have never had that issue before (particularly nexusmods which I use regularly). Something else is probably wrong with your setup.

There are migration tools, but not a good bulk one that I could find. It worked for my repos except for my unreal engine fork.

I’d love to help community host stuff, but I’m terrified of someone posting cp to a server I have or getting breached.

Both of mine died lately and I want to get them working again, but qmk is a nightmare I don’t want to have to touch again.
