Very useful for multiple email windows. It would be nice if there were a customizable key combination to pause all slideshow windows, and a feature to pause the slideshow whenever the window was selected.

Could you please add a shortkey to toggle addon, e.g. by adding to manifest.json

"commands": {
"_execute_browser_action": {
"suggested_key": {
"default": "Ctrl+Shift+B"
}
}
},

It works for me on Linux Firefox 66.0

Thanks.

Parfait, ultra simple, et fonctionne !

can you please add the option to start it in slideshow?
so when you start firefox it starts with the slideshow, so you dont have to press play

that would be awesome

I was missing this feature since tabmix plus!! great work!
