On Windows 10 worked flawlessly. After migrating to Kubuntu there are so many bugs - sometimes it enters a mode when window never opens (just Firefox flashes in task bar) other times it works for some smaller images, but breaks for larger - it shows them on wrong screen (TV actually which is quite far away so unusable for me).
This review is for a previous version of the add-on (4.0).Sorry, it works pretty well on Red Hat Linux, the one I test on. But there are many flavors of Linux with different window managers, some of which don't behave similarly enough to Windows and Mac for the add-on to work properly.
