I tried to reproduce your problem but I was not able to. Are you sure that this Addon is causing your problem? It does not do anything on the main Netflix page. It should only be active on the list page and the page where the video is played.

Does it happen on a specific page or after doing specific things?

We can further discuss your problem on the follwing page (further replies are only possible with edits here but without notifications): https://gitlab.com/konstantin-mueller/better-netflix/-/issues
