Firefox Aurora is the equivalent of Chrome’s cutting-edge Dev, which means it’s definitely not for the average user. Firefox Aurora is now v7.0a2. The latest Firefox 7 brings a number of fixes to the memory footprint, particularly for users who like to keep multiple tabs open and iconify rather than close their web browser. Other changes include dropping http:// from the awesome bar and painting the sub-domain element of a URL in lighter grey.
[advt]It’s effectively an alpha build of the next version of Firefox more stable than the nightly builds produced for developers. Make sure your computer is backed up before installing this, but once done; you can install it and get an early glimpse into the future of the Firefox browser.
It’s worth noting that Aurora can be installed alongside the stable release of Firefox and run separately, so you can test drive in conjunction with a final release of Firefox rather than in place of it (as is the case with Chrome). However, there will be an add-ons compatibility check each time you switch versions, so bear this in mind.
Aurora will be synchronized with the Nightly Build server every 5-6 weeks, which means it’s significantly less stable at the start of this period than at the end when its changes migrate into the Beta channel.
