I was using some browser in the past ( Dolphin, Samsung stock, Chrome, Naked Browser, Opera) but now im remaining at AdBlock Browser & Yandex paired with AdGuard.
I like Firefox for Android, but there are too many bugs, especially with how Google and associated websites bugger up the content served to Android Firefox. Due to the problems faced therein, I have switched to Yandex Browser for now on Android. A meeting is scheduled between Google and mozilla in June to discuss these issues with rendering of Google pages on Android Firefox. If progress is made, I'll switch back in a heartbeat.
I really like Via for Android. I can almost hear people saying 'Via - what's that?'. It has a very minimalist UI for a browser but don't be deceived by that. This has all the usual tools that we expect from a browser. And, it has no add-ons. JPC
"Other" Yandex, I started using it because of it's ability to utilize AdGuard, and after a while I realized what a awesome browser it was for mobile. It and AdGuard together equals fast and safe, a duo I appreciate.
