The app hasn't been updated in six months according to F-Droid when I used the official Bromite repo. I mean no disrespect to the Dev I'm just concerned about security vulnerabilities in the browser. Bromite was considered one of the best in the privacy space and I'd hate to see it go. If anybody could shed some light on this that would be great.
Github shows the same: Last commit 5 months ago. Funnily enough, the main dev's last comment was "Nobody quit anything" right after never showing up again.
I had the same issue recently, since sometimes you need a chromium-based browser. After some research, I decided to opt for Mulch. It is available on F-Droid through DivestOS repo just as Mull (my main browser).
I am pretty sure the app got abandoned. If you want a nice Chromium based browser I would highly recommend you check out Vivaldi. Their recent interview with Techlore also made me feel much better about them. While I know that Brave is an option, I personally can't bring myself to trust an ad driven for profit company to run my browser. But if you can trust Brave then that is also another great option.
