Where has this wonderful addon been all this time! Glad I found it :3 Simple and easy to use and you can set .png as default for example, and that's about it. Just works!
Though I wonder if it could also override ctrl+s etc. actions.
As for Ctrl+S, Firefox doesn’t let extensions override default shortcuts like that, it’ll always try to save the whole page. But I might be wrong, I’ll look into it.
