I have Firefox and I've been using it for several years. I like how it has the AdBlock Plus feature, which blocks virtually every ad, even annoying video ads. C:
I used IE, then heard about how much better Firefox was and downloaded it. Since IE wasn't that bad for me, I ended up not using Firefox. It's been crashing for the past weeks, though, so I'm giving Chrome a chance. Everyone seems to love it.
I have Google Chrome on my computer and it's fast and I really like it. The thing is it's too simple and I don't like that so I use Opera, which I love to death.
I think the most common browser these days is Chrome. Everyone has and everyone loves the simplicity and fastness of it.
Firefox as my main browser and Chrome as a back up. I just don't like Chrome's layout very much. I missed having my bottom bar for statuses and stuff, and the fact that it doesn't have "File, Edit, etc" at the top to begin with bothers e too. I do like, however, how it has coding similar to Firefox. I use it often when checking on my layouts and site compatibility.
