So yeah it worked fine for like half an hour, then it hung again. Used task manager to kill it. Reopened, took only a few seconds and then hung again. Repeated, same thing. I have no such issues with other browser tabs or other software. Only whilst I'm actively browsing Gatefans this situation occurs. But when it does happen the entire browser is unresponsive. Has been happening for somewhere between one and two weeks. Maybe this has something to do with a Firefox update or a memory leak or perhaps there was a forum software update or something. I dunno.
