Hi I am running Firefox 103 on my lenovo thinkpad T570 running windows 10. Streaming any video (e.g. BBC iPlayer or GCN+ or any source I have tried) Video very choppy, freezes for several seconds while audio continues as normal. this is essentially unusable. Task manager shows firefox running at 70% or more I have tried all the power management settings and that makes no difference. The Nvidia Gforce940 appears not to be used at all. All my drivers are up to date I have tried firefox troubleshoot mode, which makes no difference full screen mode or not makes no difference (its a 4k screen so I wondered if it was doing some kind of upscaling) makes no difference whether I run on external monitor or internal. Also makes no difference whether the laptop is connected to my thunderbolt dock or not. I can run the same content side by side in Chrome. Chrome displays the video smoothly with no glitches at all and consumes around 16% CPU (still no Nvidia GPU utilisation)

This problem does not happen on my other PC, a 5 year old Intel NUC, with i5 cpu, also running win 10 connected to my TV.

If i can't fix this I will have to very reluctantly revert to Chrome for video streaming I havent worked uot how to obtain the troubleshooting info to share but happy to do this if necessary

many thanks John

Hi jcpw, You've tried Troubleshoot Mode and your drivers are up-to-date so, troubleshooting info probably isn't helpful right now. It's a good idea to include the info whenever you post in the future.

You could try a new "test" Profile - In Firefox Enter about:profiles in the address bar and press Enter You will see at least one Profile named default-release (or default) and This is the Profile in use and it cannot be deleted. Near the top left, select the button Create a New Profile Go through the Profile Wizard and a new Profile will be created.

Under the Profile In Use be sure to select Set As Default Profile again. This will ensure that your Default User Profile will launch the next time.

Under the New Profile select Launch Profile In A New Browser.
