On my machine (windows 7 x86 - AMD HD 6670) hardware acceleration for video seems to be disfunctional since Firefox 109. Im using Firefox Portable Version. with Firefox 108.0.2 GPU acceleration for Video was still working. after upgrading to 109 - with the same profile data, addons, settings, drivers etc. - it is not working anymore.

Example Video: https://www.dailymotion.com/video/x770v7x

With Firefox 108.0.2 and ESR 102.8 playback of the above video is accelerated by GPU on my machine. Since Firefox 109 and following versions it is not...

Because i did not changed any configuration before updating to 109 it is obvious that 109 and the following versions do not support video acceleration in my environment anymore. but why..?

I work on computers without admin rights, and i can't install add-ons,

how to make a true portable Firefox without using registry at all

I really don't understand that a free software allows such a blocking, even if chrome doesn't pose any problem with add-ons.

is there a way to lanuch firefox with a option to not use registry or to redirect registry in file or in a not locked custom registry like

hkey_local_machine/software/policies/Mozilla_portable/Firefox

or something like that ?
