You may already have the new Firefox 3.5 browser, but now, courtesy of the folks at PortableApps, you can get the portable version of Firefox 3.5 as well. It's downloadable here, and, like the other portable versions of popular open source applications that PortableApps offers, it's perfect as a lightweight app that you can keep on a USB thumb drive or other portable device.  It comes bundled with a PortableApps launcher, so you can launch it directly from a USB thumb drive and have Firefox available with your customizations no matter where you are.

Now that Firefox 3.5 has been released, you may be interested in customizing your experience with it, and learning more about the many new features available in it. Here are over five good resources worth spending some time with if you want to get the most out of what I consider to be the best, most extensible browser.

Mozilla released Firefox 3.5 today, roughly one month since it was pushed out as a Release Candidate. The major update delivers several new features and performance improvements that make this new version one you won't want to miss.

Firefox 3.5 is designed with new Web standards in mind and contains support for new Web technologies that will make it more interactive and speedier. Indeed, our own Sam Dean took the beta version out for a spin and was "happy enough with the speed to use it as my primary browser and reach for an older Firefox version when I need extensions."
