videoresumer av hans

This extension automatically resumes the video you were watching when you last closed the tab.

I made this extension because https://addons.mozilla.org/en-US/firefox/addon/video-resumer does not work on Android (it is marked as Android-compatible, but it does not actually resume videos on youtube.com on Android. This extension /does/ work on YouTube and Android.)
