Firefox is the newest browser from Netscape's Mozilla project; get yours here. I am posting from this new browser today because all of my links and bookmarks imported fine from IE. In fact, I barely notice the difference in the way this new free browser renders my MT interface.
Mozilla is an Open Source project, so support of it at AdvisorBits should come as not suprise. Another thing I like is that Firefox claims to be more secure because it doesn't run ActiveX controls. Instinctively this appeals to me as a user, although I am also a fan of some applications where I think I will need ActiveX controls.
If Firefox is the default broswer it forces the user to choose to use IE in those instances where the ActiveX controls are trusted, and so it makes the user think about security.
Users who are conscious of security are good things in my book.
