I have been using Firefox for basically as long as I can remember and I love it. However, there’s one website that I go to Chromium for: GeoGuessr/Google Street View. For some reason it’s unbelievably slow and sluggish in Firefox whereas it works normally in Chromium. Why could this be? To be clear, it’s only the Street View part (and moving/panning/zooming) that’s slow on GeoGuessr.
I use Arch (btw) on my daily driver too, but I recently switched to Mint on my server. Too much of a hassle to constantly update on Arch. Though I do miss the AUR.
