I’m thinking about switching to a Firefox fork as a web browser. Apart from Tor, they’re all on AUR. I can’t use Tor all the time.
Do you consider that a security risk that’s worth worrying about? E.g. you could get a dodgy maintainer putting malware in it, as least theoretically.
You can also download and read through the PKGBUILD first if you are suspicious. (You just have to remember this with every update)
