Firefox – do to preserve tabs when restarting Firefox

firefoxreboot

In the Add-ons window, if I enable/disable an Extension, a yellow bar with a "Restart Firefox" button appears. This tells me "Firefox will try to restore your tabs and Windows when it restarts."

I want it to pick up some new plugins, and not enable/disable any existing ones. How do I restart Firefox manually, without losing my tabs/Windows?

Go to Edit > Preferences > Main > When FireFox starts and select Show my windows and tabs from last time. Once. After that, you can close FireFox, and it'll be remember everything you have open to show you next time you start it

[edit] For Firefox 5 on Windows, the option is located at: Tools > Options > General > When Firefox starts: Select "Show my windows and tabs from last time"
