First came all the praise about Firefox 1.0 being more secure than Internet Explorer (IE). Then came headlines about mega-downloads chipping away at Microsoft's market share. Then came months of uncovered flaws and security updates that now has Firefox up to version 1.0.7.

Now comes Firefox 1.5 in beta, an upgrade Mozilla Engineering Director Mike Schroepfer said will be more secure than ever, with an automatic update service that downloads patches as needed. Indeed, blogs and Web sites are buzzing about the beta release, including MozillaZine, WebmasterWorld.com and PC World's blog.
