On Firefox 142 (nightly):

Cropout: After being stuck at 0% for a long while and 1200 network requests, it loads to a menu with a black background and will start a game but only UI elements show up. Seems to have a lot of errors parsing shaders, as well as a few other miscellaneous errors.

Car configurator: Several errors while at 0% (never loads), the first among them being `[223402304]: MessageBox type 0 Caption Message Text Game files required to initialize the global shader and cooked content are most likely missing. Refer to Engine log for details.`

I would concur with others that you should at least test this in Firefox before advertising it here.
