Fine work: thanks!
But can you add an indicator to remember i have your script working for these videos?
I test many userscript and extension and it became difficult remember what it is possible in a page without visual indicator :-)
The video popup (on Firefox) take time to open:
can you make faster ?
It should be great too to have some test links
