There is a Firefox Extention but I don’t know how many of the features you mentioned it has as I have exclusively used Karakeep on my phone and the app has all those features.

I have been using Karakeep for the past couple of months it works great.

Brian Cranston, Leo DiCaprio, Tom Holland, Zandaya, Florence Pugh just to name a few.

I’ve been using Fennec and it works 99% of the times and on the rare occasion I need Chromium based browser I use Brave. I don’t have any issues with either.
