I already had Manifest v2 extensions, specifically uBlock removed from Chrome. There are solutions to extend this to mid-year, and I can report that they work (search for ExtensionManifestV2Availability)
Stuff can change. Who knows. I might switch platforms until then so my choice might become invalid. I might die. No reason to do it now, when there is plenty of time.
I'm a happy Firefox user on mobile though (yeah, I know, I know the recent changes in their legal stuff)
Look into about:support, what does `HARDWARE_VIDEO_DECODING` and sibling features say? If it's off, you could try force-enabling video acceleration by setting `gfx.webrender.all` to `true` in about:config. I've had it force-enabled for years with no issues.
HARDWARE_VIDEO_DECODING does not exist but there's a bunch of rendering options. They are all set to default and available except for a few things like DIRECT2D is disabled and WEBGPU / REMOTE_CANVAS is blocked.
gfx.webrender.all was set to false. I will give true a try. Thanks.
