After using Chrome for a decade and switching back to Firefox, one feature I missed was the ability to right-click and Go to [url] directly, for any selected text that vaguely resembles a URL.
I made Goto foo to approximately replicate Chrome's behavior in Firefox, but it would be nice if no extension were necessary.
I just did exactly that, with both the link in the sidebar and the substring “lemmy.ml” from the full “firefox@lemmy.ml” string in your comment. It works different on Firefox, I suppose as a by product of being implemented differently, but it's not less powerful. Your plugin is cool and all, but it's use is extremely niche to save fractions of a second.
