OK, so this is a short and quick post just to clear some confusion. I spent hours and hours trying to figure out what the hell was going on when I was running into this NS_ERROR_CORRUPTED_CONTENT for javascript files

For the life of me I couldn’t figure out what the cause was for this error. It turns out that, at least in some situations, the error is actually more confusing than it should be. When I opened the URL in my browser, it turns out that this was simply a 404 or 403 (I have two different situations where I encountered this). There is nothing corrupted about the response even though the error seems to imply that. Don’t get fooled by the weird error string, just inspect the response and check the status code and you’ll probably quickly figure out what the actual solution will be.
