I believe windows 7 tab previews and ctrl-tab tab previews already create/update and store thumbnails on each xul:tab item as __thumbnail. Tabcandy probably shouldn't duplicate the effort.. especially if it's doing it like bug 580954. I believe there was a concern that the existing thumbnails were too low resolution?

Don't the existing thumbnails update themselves re: their resolution over time? That is, if you make the thumbnail bigger it should after a little bit become higher resolution.

I think in the above comments, Mardak is using the term "existing thumbnails" to refer to the Windows 7 tab previews, and Aza is using the same term to refer to the Tab Candy generated thumbnails. At any rate, if there are thumbnails of a suitable size that update frequently enough, available on all platforms, we certainly should use them. How would we find out about such a thing? I believe there was talk at some point about creating a general thumbnail service in the browser... don't know if anything's happened with that.

Note that there are some suggestions for places to grab thumbnails in the comment thread for bug 580954.

Recent conversation in IRC: dietrich: iangilman, seandunn: https://bugzilla.mozilla.org/show_bug.cgi?id=497543 firebot: Bug 497543 nor, --, ---, nobody, NEW, Provide a thumbnail service dietrich: the first patch is a super basic thumbnail caching js module, that uses the cache service for storage dietrich: the second patch is an xpcom component that provides a url scheme for loading images from that cache dietrich: i'm not sure if the second patch is the right approach. there's probably a way to do it directly from the cache dietrich: maybe dietrich: but it makes it so you can just do moz-thumb://yoururlhere, and put that in a src attr, or whatever dietrich: or you could use some identifier, if you have unique ids for the tabs dietrich: panorama-thumb://tabId dietrich: i like the general purpose thumbnail service, since all add-ons could use it, etc dietrich: but not really necessary just to solve this problem iangilman: yeah, I don't know that we're ready to take on the whole show

bugspam: returning Sean's bugs to the pool

Bug 604699 has landed. Thumbnails are stored in the browser's image cache rather than in sessionstore. Shall we make this as fixed?

Yup, I suppose that would even make it a dupe.
