Chrome. Firefox used to be great but it's bloated nowadays, and IE is, well, it's IE.

Firefox since college days (early 2000s). Before that I used Netscape. I stay away from IE at all costs.

Opera 12.

But I like Safari and Chrome too... Firefox and IE are the worst.

I use FF most of the time, especially on my laptop. Opera is my preferred browser on my phone. I use safari now and then on my laptop, too. Chrome, almost never.

Did you know the Chrome version doesn't really block the ads? It still loads them, but it just keeps them hidden from view.

OT: Firefox. Gave it a try way back in '05 and never looked back. Well I shouldn't say never; around FF3 is when it became ridiculously bloated and buggy, and I was within an inch of ditching it for Chrome or Opera, but it has become tremendously more usable since the rapid release cycle.

For everyone saying Firefox is still bloated and slow, when is the last time you actually used it? Yes, Chrome is still faster, but the difference is pretty much negligible. Unless you're The Donald and every second of your time is worth millions, or unless you're Jack Bauer and you need to boot up your browser within milliseconds to stop a bomb, I doubt you're really saving time. Not hating on Chrome, but I'll take FF's customization and quantity/quality of add-ons over a trivial speed difference any day.

Took a look at Chrome and I don't know why people are saying it has a good UI.  To me it looks like shit.  I like the presentation of Firefox way more than Chrome.  Sure I perhaps didn't fiddle around with Chrome as much as I should have but it gave me no reason to.  To me Firefox is still the best and all other browsers are following it.

People like Chrome for it's simplicity, or at least I do. All I need is the URL bar and the tabs, and maybe the bookmarks bar. Everything else seems unnecesary. Whenever, I go on Firefox or Internet, all that extra content at the top makes it visually unappealing (though I haven't used Firefox in a while. Has that changed?). I'm not sure how Google's UI looks like shit when it only accounts for like 5% of screen space. The rest goes to the webpage.

Opera, used to be Firefox but I switched like 2 years ago.

Chrome since the week it first released.

Synchronized bookmarks just rule !

When the screen is maximised, the Firefox button is on the same line as the tabs. It is much like Chrome, but it keeps the separate search/address bar. Firefox is much, much better than it was during the 3.x releases.
