Firefox 5 was released yesterday with comparatively little fanfare. Firefox 4 only came out 3 months ago. And realistically, this is more deserving of a version number like 4.1, not 5.0. It’s a marketing decision more than a technical one. But it contains 8 critical bug fixes, a few stability fixes, and a few rendering fixes, so it’s worth grabbing, and treating like a point release, not necessarily with the usual trepidation that accompanies a major release.If your browser hasn’t already grabbed it and prompted you for installation, I recommend you go get it.
And a new version, most likely to be called 6.0, is expected in another three months.
