I use Adobe lightroom to export images to Facebook - I am now getting error message related to this process address not understood- how to correct?

Question

I am using Win & Home edition / Mozilla Firefox on my HP laptop. On Oct 8 I used Lightroom to export images to Facebook. Now when I try to repeat this, authentication fails as The address wasn't understood
Firefox doesn't know how to open this address, because one of the following protocols (lightroom) isn't associated with any program or is not allowed in this context.
The export process was working, but isn't now. I have ben having problems with Firefox - I wasn't able to retain the settings for opening with my own Homepage (kept going back to Firefox default. So I have done a reset. Seems that this has somehow disrupted the authentication process. Can you help please.

I just dropped into the forums to see if other people were getting the DVD burning verification error (Error code 0x80020063). I've been holding off on the Tiger to Leopard upgrade until very recently. All of my must-have apps were anecdotally stable and I was under the impression that 10.5 was too. Apparently reliable DVD burning is Tiger only, at least on my systems.
We've been burning Taiyo Yuden DVD's almost daily with Tiger with incredibly low failure rates. After what seemed to be a smooth upgrade of a Mac Pro tower & 2 MacBook Pro laptops (one is a Core Duo and the other is a Core 2 Duo) I've spent the entire afternoon troubleshooting until I ended up here. Some searching on the board leads me to conclude that this will be a bigger headache than I imagined.
I've done all the obvious stuff (varied the burn speed, moved the files to a different drive, reset PRAM & SMC, used a different account, deleted finder.plist, tried repairing the system with DU on the Leopard install disc and then I tried burning on different computers with different media). What I'm finding is that over 50% of my DVD's are throwing the error code during verification across 3 different models all running Leopard 10.5.2. CD burning seems to work as before (but we don't use this as much so ?). I saw that some people had posted that closing the finder window helped, but that didn't improve my overall failure rate. The DVD's appear (indentical byte size and item numbers) to be burned correctly and usable, but I need to be sure so I can't trust them.
We need reliable DVD burning for our business and this is a real problem. I was going to trudge over to the Apple store, but it doesn't sound like there's a real fix yet.
