Hi
Thank you for helping to test the Nightly build of Firefox.
Please appreciate that the Nightly build is still very much "under construction" and may have unresolved issues. Does the problem occur in the main Release build of Firefox?
Are you able to provide an English translation of the two error messages?
Do you have a link to the video that you are trying to view?
