Reproduced the issue on Firefox 83.0 under Ubuntu 20.04 and Windows 7 by verifying google maps and low performance from the link found in Comment 23.
The 3D map works, and the performance is good for the link found in Comment 23 on Nightly 87.0a1 (2021-02-03) and Firefox 86.0b5 under Ubuntu 20.04 and Windows 7. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1905054 Title: Firefox 83 Breaks WebGL To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1905054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
