“found this page when googling “firefox jpeg” to find out why i cant view some jpegs that have a clear layer. all i determined was, “yep, i cant read this page”. wish it was more help.”

Firefox + ‘tagname2’ is not working currently due to memory limitations on our hardware and a limitation of our current algorithm for determining tag combinations. It’s not a trivial fix but we are working on it – thanks for reporting it.
