On this website (https://www.alltrails.com), I’m getting a MapboxGL error:
It appears that your browser does not support MapboxGL, a library that is required to render maps on AllTrails.com. Please upgrade or change browsers before reloading the page. See Browser support | Help | Mapbox for more details. Contact customer support with details about your device and browser if issue persists.
The Flatpak Firefox (same version) works as well as Google Chrome. I tried the fix shown on https://onxmapssupport.zendesk.com/hc/en-us/articles/4414111261581-Web-Browser-does-not-support-MapBoxGL, but it didn’t work:
Fixing the MapBoxGL error in Mozilla Firefox
- Go to about:config in your address bar.
- Search for webgl.force-enabled and make sure this preference is set to true. If it is currently set to false, click the toggle icon on the far right to change the value to true.
- Search for webgl.disabled and make sure this preference is set to false. If it is currently set to true, click the toggle icon on the far right to change the value to false.
- Restart Firefox.
Note: This is on KDE and Gnome X11. KDE and Gnome Wayland are OK.
