I use Firefox 150.0. Flightradar24.com reports that my browser doesn't support WEbGL2. However it reports that Firefox supports WebGL2 since version 51.

You can check if there are WebGL errors reported in the Graphics section on the about:support (Help -> More Troubleshooting Information) page. See also:

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click "Refresh Firefox" in the Troubleshoot Mode start window
