Thank you Jake and others. I'm trying Brave right now, working out bugs. I'll probably try Opera too then decide which I'll keep. But Firefox will be gone!
BTW, I also use Thunderbird, is there an alternative to that?
If you are on Windows I can't help you. If you are on Linux this email client is much simpler than Thunderbird, but does the job well enough.
https://wiki.gnome.org/Apps/EvolutionThunderbird is a monster piece of software and unnecessarily so IMO.
