Anyone else using the Brave browser? I have been playing with it on my 2008 Solus Plasma machine and page refreshes seem a lot faster than Chrome and Firefox. Thinking of switching to it on my 2019 machine but its just loading the tabs up again to how I like it.

Yeah, i switched to it on a regular basis. For work (web dev) and private purposes, too.

I used it for over a year on all my devices, but switched to Vivaldi a few weeks ago

Never used it and never will be. I am still using Firefox and Vivladi.

I often recommend Brave to other users as a good replacement for Chrome as I like the privacy settings which don't seem to break too many websites.
For my own use I still find myself returning to Firefox, partly because there is familiarity and no new learning curve but also because Mozilla extensions feel a bit less restricted than the Google ones.
Been testing out Zen Browser tonight which is based on Firefox. Not sure if that will be my new go-to yet but certainly gave me food for thought.
