Using Opera Browser

10-15 years ago i was using only Opera because it had support for WML so i could browse mobile web sites (in that time only few mobile phones supported HTML). Then i switched to Firefox 3.6 and then in the time of Firefox 18 or 20 it become slow so i switched to Chrome where i still am.
Beside Chrome i am using Opera, Opera Neon, Vivaldi, Firefox and believe it or not i have to use IE 11 because of some old plugins.
