Isn’t it going through some controversy of its own at the moment? I understand they want to “source available” rather than keep open source features they’ve developed, because others are forking their work.
The irony being not only are they a fork, their initial feature set was from existing add-ons that they were just downloading/installing by default.
I genuinely don't understand the appeal of a closed Firefox fork. At that point why not just use Vivaldi?
Anyway, after googling the issue, the running of that browser is a bit too amateur hour for me to rely on for something as sensitive as a web browser, even if they have reversed course on the decision.
