Asa of the Mozilla Foundation has compiled an impressive list of weblog praise for Firefox. This is impressive, but of more importance is mainstream coverage like this ZDNet article (granted ZDNet is mainstream in the technology industry only). If you are reading a weblog, it is probably quite likely that you have heard of Firefox or one of the past names.
Of course, the point of Asa's list is to point out how many people who know about Firefox and have given it a chance are praising it. The tricky part for Firefox is figuring out how to get general IE users to know about the browser. Average users have shown they are willing to download third party software such as Kazaa, even if it's laced with spyware, if it gives them some benefit.
