Shutterfly.com plug-in crashes Portable Firefox, but not Firefox itself?

I signed up for Shutterfly's photo service - I have friends that rave about the service, and it all seems good so far. The problem is that Shutterfly's plug-in for mass uploading of pictures crashes my Firefox Portable. They specifically work with Firefox and have had no similar problems there.

My question:

With all the users of Firefox Portable, is anyone else successfully using Shutterfly? [ie: is it a problem specific to my computer?]

Is there a way I get someone else to try Shutterfly and see if they can duplicate this error?

If it is a real problem and not just me, does anyone have advice I can pass on to Shutterly's tech people so they can modify their plug in to also work with Firefox Portable?

This is part of the message I got back from their tech support:

I must say that this is the first time I've heard of Portable Firefox, but now that I've done some research into it, I think I can say pretty much for sure that it is specifically this version that doesn't work with our plugin. Our plugin not only installs as a plugin within the Firefox folders, but also installs a file into the Operating System as well, and it requires that file be there in order for the plugin to work. One thing that might work is if you kept a copy of the executable installer for the plugin on the flash drive, and simply installed it on each computer you were using at the time.

I have filed a bug on this issue for our Engineering and IOPS teams to take a look at, but I would expect it to take a while before I can get any sort of testing or development done. Your best bet, however, is to just stick with a standard installation of Firefox and a standard installation of our plugin for best results. If I find anything else out about this, I will let you know, and if you find out something or figure something out, let us know, I'm sure the Engineers would love to hear it. :0)~
