Оно работает, вот только зачем оно не понятно.

Has a bug that causes the scrollbar to appear in fullscreen mode when skipping.

Really handy addon, shame there's a need for it (I get it though).

My biggest gripe with it is that with every seek in a video, it pops the settings window open. This makes it impossible to seek with the keyboard without getting harassed by the settings popups.

It would be nice if it gave the focus back to the seek bar (or the main player element) after tweaking, and if it didn't make unnecessary adjustments every 10 second seek.

Great extension, really helpful, but...
There's an issue when using the "Copy video URL at current time" option. After opening the link with a time parameter the whole youtube page is reloaded after a second or two and the video starts from the beginning.

great add on! but in recent weeks, the setting option has been popping up on its own? the one that let us select the resolution of the video. Can you fix it? i saw other reviews left by others someone got that problem too! thanks
