Internet Explorer - bad reputation
Firefox - it's cool, but it freezes sometimes
Opera - sometimes it crashes
Google Chrome - when I am using any other app, pages load so fucking slow (f.ex. playing LOL and trying to check build online = failure. then I open Firefox and.. omg, insta page open)
Maxthon - never used
Safari - never used
K-Melon - never used
So, I am using Chrome at first place. When I am playing or when Chrome fails with page loading, I use Firefox.
