It's difficult to create new window sizes. Sometimes it creates two instead of one, and other times it just deletes them. Plus, even after removing the default ones, they keep reappearing automatically.

Doesn't work. The instructions say "simply open toolbar popup UI and click on desired layout"... er, what toolbar popup? I don't see any new icon or any UI for this extension. Maybe it worked in the past, but it doesn't work now.

blocked me?

perhaps reading the reviews might have helped, i was thinking this would allow me to set the size of a page, something i was looking to use for twitch and youtube to scale the videos so they'd look good at low resolutions on my giant monitor, without making the browser also small.

this browser does what it says tho, it resizes the window and not the page. unfortunately not what i wanted and i didn't understand what it was saying until i tried it.

It doesn't work okay in my FF 70.0.1 64-bit. Deleted.

The vertical size is limited to 1200px. Just why? I have a 4K display and 1200px is not enough for me for utilizing the entire vertical span.

Constantly loses settings. Pointless.
