I had trouble with a kodak disc that came with a camera. It sounded to me like you were talking about the discs with photos on them from a photo lab. Am I mistaken?
They're very similar. Why not just get a USB card reader and edit with Irfanview? Works better for me with my Nikon. You could also use Bibble, it's great.
If you do the Firefox thing install some add ins. I use UserAgentSwitcher, Adblock+, FilterSetGUpdater, CustomizeGoogle, NoScript, Unplug, Scrapbook, Flashblock, Fasterfox, Safecache, and Safehistory.
