It depends which version of Firefox you are talking about, but based upon 4.08Pre which I am currently running -
Load times are fast and javascript speed is very similar, if not better than Chrome [1]
Currently, only the mobile version of Firefox will have tab separation in the form of the electrolysis project for the upcoming version. Plugins do currently run independently of the browser process.
Extensions in Firefox are a lot more powerful; they can slow things down and cause memory leaks.
In the latest prerelease, pages and their plugins do not reload when detached.

edit: Disabling the javascript features of firebug allows Firefox to use its jit tracing leading to faster javascript speeds.
