I just read through the 65LOC source, and it's because it swaps out an active or inactive extension icon based on your active tab.

You should have read a few more lines of that source - it also sends an "active" message to the tab, which is what adds and removes the copy/cut/paste event handlers.

Huh. That seems not super important to me. Presumably he could make a option/version where the icon didn't change?

Yeah, seems like a lame excuse to permissions grab crazy privilege.
