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.

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.

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.

You need to detect and stop sound. You swap out active memory.

What does any of that have to do with making sure input fields are pasteable?
