@gemlog Major downside of FF screenshooter is that it copies image data to clipboard in PNG — those are huge if what you are capturing has images, there is no way to configure this — but you can download/save it as a file, then I open it in imv and there I have a shortcut Ctrl+Shift+J that converts it to jpeg with ffmpeg and copies the resulting file's path to clipboard — so I can paste it to other software — a hassle, but nothing big.
