For those who use Firefox 3.5 but also want to use Gmail with no network connection, Google has an answer: a new version of its Gears plug-in.
Gears endows browsers with some new abilities, including accessing some Web applications even while a computer is offline and juggling multiple simultaneous tasks more effectively. And using Gears, Google last week began letting people see their location on Google Maps by clicking the small circle below the navigation controller and above the zoom controller.
Major updates to Mozilla's open-source browser often break add-on compatibility, and the earlier version of Gears wouldn't work with the. The new Gears 0.5.29.0 fixes that.
