Works really well and can be paired with the WebAppMode (WAM) addon; together they can auto-enable the PopupWindow for specific web pages.

the height/width setting is not working and the popped window cannot maximize

Works well with some issues:

- Maximize button on pop-up window is disabled/greyed out--pop-up windows cannot be maximized with the maximize button
- would be nice if the pop-up windows was the same size as the window it was "popping up" from, rather than a pre-determined size

That's useful for borderless need. I open several webpage to look borderless documentation. It's Very good!!

Great add-on !

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)

Nice extension. Is it possible to implement alt + click, left + right click or something similar for activation?

It just works

Great extension...must have!

The extension used to hide the mac title bar on the standalone windows, but this has recently stopped working. Any ideas why?
