I just realized that the about:support output above is actually for Firefox 82, which is odd, because it does work even though the output suggests it shouldn't.
Here's a lot for Firefox 83. The relevant section is different once again: Decision Log HW_COMPOSITING: available by default blocked by env: Acceleration blocked by platform OPENGL_COMPOSITING: unavailable by default: Hardware compositing is disabled WEBRENDER: available by default disabled by env: Not qualified WEBRENDER_QUALIFIED: available by default denied by env: Not on allowlist WEBRENDER_COMPOSITOR: disabled by default: Disabled by default (...) ** Attachment added: "f83.txt" https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1905054/+attachment/5437543/+files/f83.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1905054 Title: Firefox 83 Breaks WebGL Status in Mozilla Firefox: Unknown Status in firefox package in Ubuntu: Confirmed Bug description: Upon upgrading from Firefox 82 to to Firefox 83, WebGL stops working. Ubuntu 20.10 with Wayland. When I try to launch a webGL game: Failed to create WebGL context: failIfMajorPerformanceCaveat: Compositor is not hardware-accelerated. Specifically Pixi says: Error: WebGL unsupported in this browser, use "pixi.js-legacy" for fallback canvas2d support. Downgrading to Firefox 82 works. Not sure if this is an Ubuntu build issue or Firefox, so I also filed upstream as well: https://bugzilla.mozilla.org/show_bug.cgi?id=1678652 I need this functionality for work, and pinning to version 82 will be problematic in the long-term.
