After a long time, finally Firefox works very well on Android. Download it from the Google Playstore. Make sure you also get the following add-ons:
1. Adblock Plus (blocks ads while surfing)
2. Ghostery (Blocks cookies, trackers)
3. Clean Quit (Quits after deleting cookies etc)
If you do attend any online education courses or webinars, works like a charm. Even has private browsing option.
