Firefox 3.7 is said to start up 25% faster on Windows and will incorporate Jetpack which is an improved interface for plug-ins that makes them easier to write, install, and upgrade.

Firefox 3.7 is also expected to incorporate the first phase of work on Electrolysis. Electrolysis is designed to improve the stability of the browser by isolating processes into separate components. Plug-ins will also be moved to a process separate from the main browser. By separating components in this way, a problem with a process or plug-in won’t crash the entire browser.

Another key improvement with Firefox 3.7 is called Weave. This plug-in will synchronize bookmarks, passwords, plug-ins, and open tabs across different Firefox windows.?
