No luck reproducing this locally, but fullscreen-only issues tend to be graphics related, so I'm moving this to that component.

Are you still experiencing this video playback freezing issue?

If so, what version of Firefox are you using? (please copy & paste the user agent info)

The current version of Firefox appears to be 138 - https://en.wikipedia.org/wiki/Firefox

Also, what operating system/Linux distro are you currently using? https://distrowatch.com/

Hi Brad,

Thanks for the follow up (5 years later). I am using Firefox 139.01 on Arch Linux and this is no longer an issue.

Maybe you should share this defect with your team with the following feedback:

• When Jon Bauman was not able to re-produce, maybe he should have shared what his setup was. There was no attempt to meaningfully engage with the person reporting the issue.
• Mozilla might want to look at how it has a back log bug over 5 years old. Knowing the rapid development of Firefox versions every 1.5 months, these kinds of backlogs should be ping every 3 times and closed if no response. In this case the Mozilla Engineer did not manage the bug, and this should have been brought to a triage team to determine next steps.

This is not the first bug I have seen Mozilla drop the ball on when it comes to Linux. It has really left the end user community with really low expectations where might as well install another web (Chromium) browser as a backup. And that is what is sad. Because most people will just use one browser. That means promising products like Firefox are being left behind. And managing defect\issues is the best way to insure customer loyalty by showing you are dependable and care about the quality of the product.

So feel free to close this bug, not as not re-producible ... but we Mozilla did not try. Perhaps we will do better next time. Thank you.
