AlphaElwedritsch Sadly, no - probably. There are some possible workarounds (editing some files), but none of them seem to work reliably in all cases. Anyway, I have downloaded Firefox 130.0.1 from mozilla.org into my home directory and it works. I suspect it's a weird side effect from some compile flag that's the culprit.
BTW: According to the estimation on https://fossies.org/linux/www/firefox-130.0.1.source.tar.xz/cloc_cs.html Firefox has over 33 million lines of code. That's more than the Linux kernel with less than 28 million. Even the open-source AMD GPU Linux Kernel graphics driver now has almost 5.8 million lines of code. Nobody has a clue anymore why things even work in software. We've made a mess of things.
