I can not move to next page

[cmpvediger]

Dear Developers,

I have been using videospeed for almost 2 years.
Thank you for your effort.

I was using speed controller on an education website, which shows videos like book pages,
at the end of every video, I need to click "next" button to move next page (video).
Videospeed was working well until two weeks ago. I can't move to next page when I use videospeed.
If I deactivate the add on, then I can move to next page.

How can I solve the issue?

Regards
