Surf the Web, block pop-ups, and keep spyware at bay with this lean and fast open-source browser

Mozilla Firefox is a fast, full-featured Web browser. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.

Firefox 3.5 is based on the Gecko 1.9.1 rendering platform, which has been under development for the past year. Firefox 3.5 offers many changes over the previous version, supporting new web technologies, improving performance and ease of use, and adding new features for users: It is now available in more than 70 languages, includes a Private Browsing mode, better performance and stability with the new TraceMonkey JavaScript engine, the ability to provide Location Aware Browsing using web standards for geolocation, support for native JSON, and web worker threads, support for new web technologies such as: HTML5 < video > and < audio > elements, downloadable fonts and other new CSS properties, JavaScript query selectors, HTML5 offline data storage for applications, and SVG transforms.

Because I use OS X, Windows and Linux Firefox is perfect for me. Using the same tool regardless of platform is a real nice touch. I actually found it faster than Safari too. Win.

For me, Firefox add-ons don't outweigh the fact that it doesn't use the OS X context menu. I have several dozen commands set up in OnMyCommand that I regularly use while browsing in Safari (and which I can use in just about any native mac app.). I could probably find Firefox add-ons that duplicate most of that functionality, but I can't be bothered. Until they integrate it properly into OS X, I'll stick with Safari.

I really like Firefox 3.

That said, I think it lacks some of the the neat integration that most OS X apps have. Makes a good backup browser for sure.

For those looking for an extension that allows to drag a file into the attachment/upload box itself (eg: in gmail), there's dragdropupload.

Also works for multiple files, and: in Gmail only, you can also drag files onto the "Attach a file" link itself,
and they will be entered into the attachment boxes.

I LOVE Firefox 3!! I was nervous about upgrading (why mess up something that's already perfect?) but it's definitely better than 2.0. It makes me want to surf the internet more! A couple particular things I love: that it asks if you want to save a password in a way that allows you to choose to save it only after you have seen that it WORKED. The fact that it has smart bookmark folders. The new address bar that shows me what address I might be typing with so much more than just the URL. Oh, and I seem to be one of the very few, but I LOVE the way it looks, no theme needed! (Except Styles to add favicons to the bookmark toolbar). LOVE IT!

Firefox 3 is an entirely different beast from Firefox 2 on OS X. By that, I mean its actually a usable browser. Not only is it usable, but it works great. I use it more than I do Safari.

Great for web development and gimmicks, but for day-to-day browsing Safari is faster and integrates with the Apple Keychain.

+1 on that grapple theme, works with the new release candidate also!

Only thing keeping me away from using this as my main browser, is the ages it takes to start the app.
