I don't use it because of mobile adblock only. There are multiple private chromium browsers which have mobile adblock, and also one supporting extensions : kiwi browser.
I use Firefox because it's a competing engine to chromium, and it looks good.
I also have all the synced bookmarks from my PC Firefox, which I use for the same reason, and because I got used to it.
It's way too big for this little amount of people, and somehow I stumbled on a porn drawing...
