This wastes bandwidth and makes it impossible to download images from certain sites, such as Rapidshare, that use download tickets and such. Reproducible: Always Steps to Reproduce: 1) Go to any page with an image on it. The following is on Rapidshare and is good for demonstrating this bug due to its download ticket system. http://rapidshare.de/files/35351148/Sonic_Adventure_2_-_B.jpg.html 2) Load up the image completely, right-click, and hit "Save Image As" (or go into the File menu and click "Save Page As", this has the same effect). 3) Observe that Firefox attempts to redownload the image and instead downloads the "Invalid/Expired Download Ticket" page instead, a much smaller file. Expected Results: Firefox should have just used the already-downloaded image that was being displayed in the tab.

What thumbnail? That site isn't a thumbnail-type gallery. Did you accidentally post in the wrong bug report?
