For a while now the transition away from Manifest V2 (MV2) to MV3 has been on-going and it looks like it is entering its final phase of deprecation, at least, in the case of Google Chrome. A recent discussion thread in the w3c WebExtensions Community Group GitHub repo has highlighted how the latest and upcoming versions of the most popular browser are expected to be its final releases with support for MV2 extensions.
What this essentially means is that the tricks and bypasses that were used to keep MV2 extensions like uBlock Origin and others alive will not work any more on Chrome, or at least not for very long. For example the Windows Registry mod that could extend MV2 availability will cease to function after Chromium version 151.
Youtube is especially egregious. I’ve tried various hardware acceleration settings and h264ify but it really brings my pc to its knees.
Im on linux, and when I run my windows vm (qemu kvm) with either Visual Studio, SQL Server Management Studio, or Fusion 360 in it, firefox on my host machine runnimg youtube just barely pushes it over the edge.
I absolutely recognize how wild what I’m asking this little computer to do is, but I can just get away with it in chromium but not firefox (since the last time I checked)
The day I can do it all with firefox I will be a happy camper
Edit: also, I specifically said games but didn’t name one… FFXIV and Deadlock both crash if I’m running youtube in chrome (and Discord at the same time).
I play elden ring, nightreign, harry Potter Hogwarts legacy, doom 2016 and eternal and a whole bunch of other shit. No issues.
Also use YouTube. No issues.
Are you using open source video drivers perhaps?
