I'd like to be able to define my own keyboard shortcuts for websites that doesn't provide them. I was wondering if there's any firefox add-on/userscript to enable generic keyboard shortcuts.
Here is a simple use case: I use google translate daily translating between Hebrew & English, and often need to switch between English->Hebrew and vice versa using my mouse. Ideally, I could inspect the DOM, pick the button I need and define a keyboard shortcut to use on this page.
Anything similar to that might exist?
EDIT: that concrete google translate example is now obsolete as google solved it with auto language detection, but the use case remains the same.
