I tried everything, and apparently that old extension doesn't work either!! https://freeshell.de//~kaosmos/index-en.html#searchkeys I don't know which idiot made this a short cut key, but it's annoying as hell, especially when you're using forum software with editors. Every time you write words like "what's" and "it's and etc.. the editor freezes up, and quick find or whatever shows up at bottom of browser! And can't finish writing in editor with words like "what's" and "it's" and etc.
