Does anyone else here use Firefox 79 as their main browser, and if so, do they experience any problems when trying to use Open Street Map? On my machine the tiles of large areas of the map simply don't render, making it useless. It's not the classic Firefox lack of memory (I've got 16GB RAM and it was nowhere near all in use.) And it's not an Open Street Map problem because it works perfectly for me on Internet Explorer and MS Edge on the machine on which it doesn't work on Firefox, and it also works perfectly for me on my iPad. I can't find anyone else reporting a similar problem in support forums, blogs, etc, but then this latest Firefox upgrade is only a couple of weeks old, I think.
