Kiwi Browser has offered an Android build of Chromium that will install and attempt to run any extension available for desktop Chrome. Most of them work.
Firefox also recently regained reasonable extension support on Android, which was a slow and frustrating process for those of us who had used it before.
Is there something about chromium that makes people stick to it? I'm sure the kiwi browser is good, but why not just use firefox or Mull Browser from the creators of divestOS.
Extension developer information from Firefox explains why it was necessary to make some technical changes. What they've never explained to my satisfaction is why they took a cautious, curated approach to it reminiscent of Apple.
The typical approach of a large open source project is to put a "here there be dragons" sign on unstable features and let anyone who wishes to use them anyway do so at their own risk, and that's the approach I prefer.
Firefox used to allow a lot more extensions though, until they switched to Fenix UI and restricted them to a selected few. And then they expanded the support again.
