firefox v152.0.6 won't load pages with webgl2

Try the steps from support.mozilla.org/questions/1580964

It says it is there, but it says it is disabled or unavailable... I never disabled nor made it unavailable.

As the page says — browser can do it, your system perhaps not. If you open about:support you can check your Graphics section for webGL version/provider info etc.

Well, i checked the webgl2 and it says true... is there something else?

This is what I have for graphics..

Maybe you need to update your nvidia drivers?

This normally only happens in virtualization, see bugzilla.mozilla.org/1970486 — you can try force setting the pref like in support.mozilla.org/questions/1334668
