Firefox 17 heads out of beta, officially drops support for OS X 10.5

We've just seen an update to Firefox for Android, but that's not the only revision that Mozilla has had in the works. Today also sees the release of version 17 of the desktop browser, which brings with it a number of changes and one noticeable omission. The latter is a lack of support for Mac OS X 10.5 (a.k.a. Leopard), which Mozilla first announced last month -- those on Leopard can of course continue to use Firefox 16, they just won't receive any updates. Otherwise, you can expect a new "Awesome Bar" with larger icons, more than 20 promised performance improvements and a new click-to-play functionality for dealing with outdated or potentially vulnerable plug-ins. Also receiving the bump to version 17 is the Extended Support Release (or ESR) version of the browser, which disables the automatic updating to cause less headaches for those dealing with mass deployments. You can find the full change log at the source link below.

Firefox browser add-on lets us try Firefox OS in an all-Mozilla universe

We've had the chance to experiment with early versions of Firefox OS for awhile -- just not in Firefox the browser, where you'd nearly expect it to have shown first. At least one person appreciates that seemingly natural fit. A new Firefox OS simulator add-on, r2d2b2g, lets us try Mozilla's upcoming mobile platform from within the company's own browser for everything that doesn't depend on native hardware, including the browser and Firefox Marketplace. The goal is ostensibly to let developers test truly optimized web apps, although the simulator is also a good excuse for the curious to try Firefox OS without the hassle of a dedicated client or a real smartphone. If you can get by the early state of the simulator and the Xzibit jokes that come with putting Firefox on your Firefox, the extension is already providing a glimpse of a web-focused mobile future to Linux, Mac and Windows users at the source below.
