I've been using Firefox for years. It was the best browser in my opinion. Recently there have been slow buffering problems. Web pages disappear, if you trying to research anything using cut/copy & paste the web page buffers, reloads with everything disappearing. It's crashing, just vanishes with no trace. Very disappointed that these bugs exist. Until it runs like the Firefox I knew for years...I'm moving to Opera.

This is technically a web brouser, but its got a lot of problems on mobile. It hides a lot of options in sub menus such as the Forward, Back, and Bookmarks buttons. You cannot set your Home page, resize the interface for ease of access, or move things around to suit your needs. It skips around when editing a search, won't alow me to reorder my tabs, and is generally difficult to work with. But it does brouse the internet, so it is technically a web browser. Use it if you have it on pc only.

Actually, firefox current version is worst. They are working on it.

blockquote message is taken from Google Play's Firefox review. Some articles also say that Firefox isn't working well in current version..

Your ram is still missing in question but since your API level is 29 so your Ram will be atleast 3 or more than 3 GB. That's why I am not going to show excuse about RAM.

So basically it can't be used. Well, yikes. I'm hesitant to use products by Google for anything sensitive like bank access. I did use Opera on PC back in the days, it was super fast and super buggy. Stopped using it because I could't trust it not to explode during money transactions etc. Admittedly this was 15 years back or so, maybe they've sorted things out.

I suggest to use DuckDuckGo browser in Android. That's best for safety. I personally like that. If you to be safe very strictly than you can use Brave browser or Tor browser. I was using Tor for few moments as a Hacker (When I was doing ethical hacking (not professional)). I am currently using Google Chrome cause other doesn't fit well in my system. But I am going to try Midori now.
