Several days ago, a user sent me an email saying that his JoyBidder eBay Auction Sniper won't load or display watch list. He mentioned that he was using Firefox 3.0.11 (portable), which I knew nothing about. After a quick googling, it turns out to be a customized Firefox that can be ran on a USB drive.
I immediately thought the problem could be related to this portable version. I downloaded the portable version and installed it on a 2GB Kingston DataTraveler. To my disappointment, JoyBidder worked perfectly fine. Well, I should be happy since I don't need to fix anything to get JoyBidder to work on Firefox portable, but on the other hand, I still don't know how to fix user's problem. Without much information at hand, I replied and asking for more specific information and also told him to read the FAQ about "3rd party cookie", (which has, by far, contributed to most of supporting emails). I also instructed him on how to use Firefox Error Console to send me error logs if he sees any. I hope he is doing fine, although I haven't got his reply yet. Sometimes I really wish all users just live nearby, so that I can just drop by and fix the problem on site.
Aside from the frustration of not being helpful, the finding of Firefox portable is really useful. Now I can load all auctions in a USB Flash drive, carry it to my office and, well, you know.:)
For fellow snipers seriously thinking of doing this, I recommend using fast USB Flash drive or better yet external hard disk. My Kingston DataTraveler works but performance is slow, surfing web is fine, sniping is not.
