PERFECT! Exactly what I needed. Now I can watch my favorite videos in huge resolution, with the reassurance that the close window button is always visible in the top-right corner for a quick exit if needed.

The extension works really well. I want to thank the developer. It’s a unique extension with no equal. The only missing feature is the lack of an option to automatically detect videos and maximize them.

I tried two different window maximizers before this one. Neither one of them did anything. I checked the settings but they were of no help. So imagine my surprise when I tried this one and it actually worked immediately! Not only did it work for the web game I was playing, but it actually added a nice looking border around the game that is not there otherwise. I'm not sure how that works, but it sure was a nice surprise!

Exactly like it says. Pop up multiple videos and fit them perfectly in the size of window you want. its amazing for multitasking! Love it, can't go without.

As a privacy-conscious user I like that it doesn't require any particular permissions namely "Access your data for all websites" as is done by similar extensions.
