Firefox pop-out confirmation window not displayed

[greweln]

Describe the bug

Firefox pop-out confirmation window to not appear on the screen when downloading and overwriting an existing image. I have to run the fullscreen keybind to have it displayed on screen.

To Reproduce

Steps to reproduce the behavior:

1. Saving an image from Firefox will pop-out the save location window: WM_NAME(STRING) = "Save Image"'
2. Overwriting an existing image, will pop-out a confirmation window in background(?), with xpropr as: WM_NAME(STRING) = " "
3. Workaround: use fullscreen keybind which will display the confirmation window as full screen.

This should now be fixed as of ca9ea78

@greweln would you be able to confirm that Firefox dialogues now work for you when running from the latest develop commit?

@sminez
Yes, it looks good. If I may suggest... to have the pop window spawned in the middle of the screen instead of the middle of the focused window?
Thanks a lot for this!

Great! Spawning in the middle of the screen is what I originally had :female_facepalm: I'll put it back to that now and then get this closed off

Gets things centred on the screen rather than inside the parent 36de5d4 👍
