My user.js
file is entirely platform independent. I use it on Linux, Windows and even used it on my work provided Macbook. FYI: user.js
only contains the settings you want to change, it’s not the whole prefs.js
file. It’s just 63 lines.
I agree that chrome feels cleaner and needs a lot less fiddling to get right, but chrome is effectively dead for me. I switched to firefox for much more important reasons than a few UI annoyances.
I think 10GbE is more intended for local applications than for internet. Say, you have a NAS with a RAID array of nvme drives for video editing purposes that you want to access from a few workstations.
Even the other day I was quite happy to have 2.5GbE when I installed my new gaming PC, and steam was able to pull all my games directly from my old computer rather than downloading them over the internet again.
Anyway, LAN speeds have always been an order of magnitude higher than common internet speeds, so I don’t see the issue.
