Feature: thumbnails cache

[eleius]

When network connection is not yet available when I start firefox, most thumbnails are either white or missin (transparent.) Could you please add caching so that the speed dial "remembers" all thumbnails even if there is no network connection?

currently thumbnails > 96px are stored locally, while smaller icons are fetched from the network. i agree it makes sense to cache them all, will patch that into a future update. cheers

Please don't forget about this issue, I'm using locally uploaded thumbnails for now
