Huh! Never heard of it. Have avoided Microbloat since... forever?
Been a Firefox user -- I don't remember any issues over the years.
Just updated three computers with the latest/greatest.
The whole "Chrome"/Google connection is worrisome, though -- security-wise.
And then, my memory tells me "Just shut down Chrome and _______ will run fine." was an actual cure to some software ills in the last few years. Is that still a thing? Does it matter to Brave??
Unfortunately, I've been around too long to think that my long-standing, well-founded appreciation of certain software (Firefox browser, for example) is a *mutual* relationship, and that things might change in a flash. So, I'm reading of Brave with interest.
