I normally use Firefox 3.6.15 (under Win 7) but notice that not long after starting a BRS tab and looking at a few forum postings the whole of Firefox grinds to a snail like pace making it largely useless. I tried the BRS site under Chrome and it runs OK except for an error mentioning that a "Shockwave Flash" plug-in crashed (happens on every BRS page I've tried including the one I'm typing this into). Perhaps it's a similar thing with the BRS site code under Firefox but Firefox does not report it (it just slows down). Hope that helps. I prefer Firefox as I like to keep all the tabs ready to reopen when I start the PC up again (so I can have the BRS site up straight away). I don't really want to have to use another browser just for the BRS.
