After bug 1680595, it should be more clear to (power) users what they can do to mitigate this.
Functionality here is, I think, working as intended now. Unfortunately the specified behavior causes certain websites (which arguably may have made poor choices) work worse for our users, whereas before things were maybe slower than they could have been, but otherwise functional. With that in mind, since we're now following failIfMajorPerformanceCaveat spec properly, it's causing breakage. This bug is tracking the user pain-point. In order to solve the user pain- point, we might ditch failIfMajorPerformanceCaveat as accidentally- user=hostile for the time being. Two choices: 1. Call these bad websites, and try outreach/education 2. Re-evaluate the failIfMajorPerformanceCaveat mechanism entirely -- 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: Confirmed Status in firefox package in Ubuntu: Fix Committed 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.
