Firefox forced me to learn how SVG works to do clipping and masking, which turned out to be pretty awesome, so I owe that to them.<p>This article was completely without any substance beyond a graph of browser share stats. That's not necessarily evidence of Firefox "dying", rather than of the market simply expanding outside of its target demographic. In any case, as a web developer, Firefox will remain a critical browser to support for the foreseeable future, and as a user, I still haven't found a better overall option to use in Windows or Linux (I've stuck with Safari in OS X mainly due to the increased performance, stability and vastly superior font rendering).
