Strange that I like it so much more than FF. And it seems faster, too. I made a portable at first with VMWare. But extensions didn't work, so I did a full install. Very nice work. It would be nice to have more cross-platform tools like this.
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.
Works good in ReactOS 0.4 RC1.
