So, I was sending a comment as a reply to a recieved gift, and I got an error message. But it's weirdly formatted, making it almost impossible to actually see...

Text in error:

Let me also note, I HAD filled in the comment box before trying to send it. I checked the users profile, though, and it doesn't look like the comment went through.

My info: I'm using Firefox 56.0 (64-bit) on a Mac with OS X El Capitan Version 10.11.2

Edit: Tried again the same way, and got the same error.

Edit: Tried again with a different gift from a different user, and had the same issue... I get the feeling I'm going to have to have two tabs open to thank everyone who sent me a birthday gift... :/

Edit: Cleared my history/cache/cookies, still have the same error, every time I try to comment through the gift center.

Edit: Forced the application to quit, and the problem is still there.... So yeah...
