Please explain the issue you are experiencing.

I have compiled a list of mostly Websites using mostly OpenStreetMap based maps which require WebGL to run, but have not WebGL exeption set inside of IronFox (and LibreWolf). Some of them also ask for HTML5-Canvas permission.

Also while the OpenStreetMap main website seems to be whitelisted or to not require WebGL by default the new vector map styles (layers=SN and layers=VN) do not work without WebGL permission.

Please provide detailed steps to reproduce the issue.

1. Install IronFox (or LibreWolf) freshly,
2. have it set to block WebGL by default,
3. visit one of the listed websites
4. observe that the map does not load (and HTML5-Canvas neither)
5. disable Firefox tracking-protection(or allow WebGL access in LibreWolf)
6. observe how the maps now are loading
