Rated 3 out of 5 stars

I've used this plugin and find out that it is useful when I try to open lot's of windows in different screen. However, it can't detect any windows except major screen. It is strange that it can detect all off screens when I install it at first time, while it lost this function when I restart my Fx. Can you help to fix this bug, or just something I misunderstand of usage?

This review is for a previous version of the add-on (7.1). 

Does the new version 7.2 still have this start-up issue?
