restart firefox, boom, you have the menu back on the window.
If you don't know about about:config, google about:config or maybe "firefox about:config" or just put it in your firefox address bar: about:config as a website. Like anything useful, about:config is dangerous. That potential to do great harm also means it has the potential to great good. Odd thing about useful stuff.
A quick search in synaptic turned up the following package: xul-ext-websites-integration. So, presumably removing that will get rid of the entry.
Personally, though, if I wanted rid of it I'd much prefer to just disable it in the Extensions menu than uninstall it entirely (Firefox->Tools->Add-Ons->Extensions->Disable next to the unwanted extension); the websites-integration package has a couple of dependants (I believe that they are just to do with web apps, but it's still better to disable than uninstall, I'd say). Having a disabled entry in the extensions list shouldn't be that much of a worry.
