For some reason my school's proxy server and web security has blocked everything that has "exofire" in it due to downloads. I don't know exactly why they do this but at one point in time I had a website and it was on the exofire extension and I couldn't access it at school. This isn't a problem now as I use the x10.mx extension. But I just thought I would let someone know that any site that uses exofire in the name gets blocked in some places.
