Dumb question but do you have any FF extensions that might be causing issues and can you disable them for the site?

Switched to Manjaro after running vanilla Arch for several years and haven’t looked back. I appreciate the slightly less bleeding edge updates and extra added stability around it.

Easy installs are probably less of a big deal nowadays after Arch overhauled their installation process.
