Template mod generator: Stuck at "loading" in firefox #129
Description
When opening the template mod generator in firefox, the mod selection shows "loading..." without showing any of the fields. I've waited for about 10 minutes without it loading anything.
I'd help debug this issue a little, but I'm not that good at web, so I'll leave it at that.
However, when opening the same page in Chromium, it loads just fine. The screenshot below shows side-by-side view of firefox (left) and chromium (right) viewing the same page.
