Debian 7.0 "Wheezy" released
It's interesting to see Iceweasel 10 on this list with a renewed perspective.  I was doing some web development last week and spent some hours chasing after an audio latency problem when using HTML5 audio on Iceweasel/Firefox 10.  It turns out that according to my web server logs, nobody uses versions that old, and when I tried using a newer version I discovered that the bugs simply don't manifest.So I recommend to Debian users who use Iceweasel: install a newer version.  You can get it directly from Debian Iceweasel maintainers, and instructions are available at: http://mozilla.debian.net
