This project is essentially a de-branded version of Mozilla Firefox, spun off from IceWeasel for Debian Linux distros.
Absolutely not in the spirit of the original project. Comes with propietary software plugins and installs unwanted toolbars and search engines across your other browsers, as of may 2014. Used to ship a trojan apparantly, see other rewiew, this is not present anymore, but there is an impression that some builds in changing types of undesirable code foreign to iceweasel. Uninstalled immediately and had to clean my chrome browser, too.
It runs great but I uninstalled because of one unresolved problem. TrendMicro Anti-Virus (8-30-2010) said the IceWeasel for Windows Installer has Troj_Gen.CZ0057 (which is their code name). It is a low level Trojan threat they said. It was in the installer download and my Firefox profile after running the exe. Possibly other locations. I will update my review to thumbs up if this is a false positive. Otherwise I have gotten only good downloads here on Sourceforge. Wanted to warn people.
