Firefox 3.5: upgrade now
Firefox 3.5, the latest version of the best desktop browser was released yesterday. Upgrade now, and you'll get cool new features like browser geolocation and native HTML5 video support, not to mention much faster javascript.
With both Firefox 3.5 and iPhone OS 3.0 out, a significant number of browsers suddenly have geolocation support. It will be interesting to see how quickly web services start to follow up, providing more meaningful content through the location context.
There is even a patch to make Firefox use GeoClue for its location needs.
