NOTE !!!!!!
1. This add-on only maximize video, it can't remove web advertisements for you.
If you need remove web advertisements, you can install other add-on to do that.

2. No promise to support EVERY video site. If it can't work on specific web site, report to me:
https://github.com/ettoolong/MaximizeVideo/issues
I will try to fix it ( if I can).

Usage:
1. Click on toolbar button
2. Select video that you want to maximize (you can click toolbar button again to cancel)
