I think its posible to use them. I already do on my windows and they work fine. No, as for me, the data isn’t shared or duplicated among the other installations unless you enable brave sync and pair it up.
Not sure. I guess, only thing would be that you aren’t installing to earn more BAT as that could be seen as farming. @Saoiray Do you have any clarifications ?
Not necessarily recommended. Just need the one version. Though you can run Nightly or Beta as well if you just want to get something of a sneak peek at some of the features to come.
Kind of. They are supposed to be but I did notice issues that I reported a while back where Shields settings were replicated across versions even though they shouldn’t have. It’s been a while since I tested, so not sure if they fixed that or if it’s still the case. Overall, each profile should be different from each other, including profiles in different versions of the browser.
I rarely use Nightly, so haven’t messed around enough to feel confident on an answer. Just would say they are supposed to be isolated and I think, for the most part, they are.
