I'd like to see how much memory Firefox is currently using in the status bar or the title bar.

I, too, would love this!

probably unpossible with greasemonkey. try this instead.

thanks, I checked out that extension, it actually shows total system memory. Not really a biggie anyhow -- I use task manager and shut it down regularly and restart. but a restart button or context menu item in firefox that doesn't wait until something gets installed or goes wrong would be useful!

Maybe I'm missing a point here, but if you want a restart menu item in firefox, try checking out this extension. If you wanted this option to appear on the context menu, I believe there are a number of extensions to customise menus.

This extension which was linked to is nice.
I would like it to also show firefox cpu usage and total cpu usage.
