I spent hours trying to set up the GUI and couldn’t get it to work. Tried the AUR, Flatpack etc and no luck. In the end I just set up the command line version of open VPN with an Alias.

I was apout to suggest this, I get leg cramps semi often and this tip is a life saver.

I just use Vanilla Firefox, I use chrome for work but all my personal stuff on Firefox, left chrome after there was talk of stopping ad blockers.
