You can change the shortcut through about:addons → gear icon (top right, above all the add-ons — the small one that opens a menu when you click it) → Manage Extension Shortcuts (last one).


Alt by itself opens the top menu, so I disabled that. Alt+S still opened the menu even after that, so I disabled that too. Then Alt+S started focusing the search box on any website that has one, so I disabled that behavior in the browser as well. And then I find out that the fucking websites themselves have Alt+S bound to their search panels.

I’m about to fucking explode. You literally couldn’t have picked a worse key combination unless it was Alt+F4. Bravo!
