The names should provide more information on what they do. Suggestions: 'Prevent accidental closure' 'Lock tab to url' I'm sure there are nuances where these descriptions don't apply (e.g. 'Lock Tab' actually allows url modification via the history api — which is is what I want in the context of an app), but unless these are not the intended behavior of this functionality, I think a rename along these lines is an improvement!
I believe the names "Protect Tab" and "Lock Tab" are deliberate. These are basically integrating features already found in many tab management addons into Firefox itself. However, if you believe you have better names, please feel free to suggest them in the firefox-dev mailing list where they can be discussed.
Wait, never mind. You *are* using an addon. This isn't a core feature of Firefox.
