I don't think this is something we plan to support in an add-ons API.

Add-ons that want to mess with tab resizing behavior will have to override the functions _lockTabSizing and _unlockTabSizing.

I don't think some add-on will want to mess with tab resizing behavior, but tab.style.maxWidth could be used to dimension tabs from the default 100-250px.
