IE- lol, I have 2 things in the history, Firefox.com and Google.com/chrome/download. but right now i use chrome.
Firefox- it looks good
Chrome- fast, functional, nothing to get in your way. one downside though, if you want to remove ONE thing from your browsing history COMPLETELY you have to reset everything.
i use chrome most of the time, it starts up faster than ff for me.. only thing i don't like is the inability to open files when downloading and instead having to save everything, sucks alot when watching replays.
no, like completely. it still shows up when you type. like when you type into the top bar sites that you've removed still show up.
