cool popup
but...
- no option to just open an empty popup (or not working for me)
- a very cool feature : ability to choose the popup/window name (for js targeting)

I use this add-on (in pair with web-app) every day, but I don't understand why I can't maximize or minimize windows (on Ubuntu and Windows this options there aren't, but seems that on MacOs works as example picture shows) and why these popup windows remain constanlty over other ones no-popup.
I prefer that developer will integrate these features as soon as possible (or integrate infos in order to obtain the same effects on other platforms).

It would be nice to be able to pop up automatically by domain and URL.

The idea is very good and that remember the position of the window is great. The problem is incompatible with some websites of movies : Netu dot tv , waaw dot tv , powervideo dot net and maybe more ... and one last thing, the full-screen button does not work and this happend in all pages
