Hovering the cursor (still?) over a tab in tab center shows a preview of that tab.
Perhaps floats at cursor at 25%.
I listen to Netflix while in other tabs - the small ‘favicon’ updates every second or so which isn’t quick enough to enjoy the video, would be nice to ‘see what’s happening’ in any particular tab without switching to it.
I’ve actually just achieved something not entirely unlike this with another firefox addon.
Unfortunately the image doesn’t update. Perhaps I’ll contribute myself to a fork of their code instead!
Sorry for wasting anyones time
Please can you tell about this add-on? I’ve shifted from Opera for a while and am sorely missing that feature.
