[Feature] Custom Postion & Size Based on URL Pattern

[HenryTheVacuum]

Custom Postion & Size Based on URL Pattern.

Or an option to save current window size/position based on URL pattern.

Example:
I like tweetdeck to automatically go fullscreen
and Google Keep Notes to be a small window on the right

Without having to do it manually every time firefox restarts etc.

Feels like a natural addition to your awesome addon!

As long as the PopUp extension does not have a site specific setup (it does have the setup for "default") this extension would have to handle that.

@ettoolong Would you consider adding that here? Is there a way to "communicate" this between the extensions?
