Body

Yesterday, it appears github.dev stopped working in Firefox for me. When I go to any repository, I get to this screen and no further:

Looking in the dev console, there's a few errors that occur:

Looking at the Network tab, I've got a little bit of a clue as to what might be happening:

For some reason, the {{PUBLIC_BASE_URL}} macro is not being replaced with some other value? This is leading the JavaScript files being referenced to return a HTML webpage instead of a JavaScript file, leading to the errors I saw above. So, I'd guess the culprit of this issue is behind whatever is not correctly replacing that macro.

Happens to me as well. In Chrome it works properly.

Seems to be fixed now (at least for Firefox), but no post on https://www.githubstatus.com/history yet
