In an interesting piece of news, NetApplications released the results of their latest web browser market share report, finding that:

...the proportion of Web surfers using [Firefox] dipped by around 0.7 percent to just over 8 percent, with Internet Explorer's share growing by the same amount.

My take is that no matter how slick Firefox looks and despite all the publicity it gets, Internet users are finally realizing that Microsoft isn't the only software company to struggle with bugs, security problems, and compatibility issues. Firefox 1.5 will reportedly include an easier patching system, presumably to facilitate the continuous and necessary stream of fixes that Mozilla has been releasing of late.
