every time i close out Firefox, my temp is dumped, not to mention, the above screenshot is the first time ever i've been through that user's gallery, so, no, caching is not the issue. and i manually dump the cache like every other day just to be certain.

also, as i said, it is not only happening in an individuals' gallery, but randomly within my own 'Favourite Images' page. i've had this occur with other user's galleries as well, and not just the above mentioned user. for example, Syyd's gallery has done this before, as has others. if i could suss out any kind of pattern, believe me, i would've posted my thoughts/findings/etc. along with the screenshot since being thorough whenst reporting an issue is paramount, but as far as i can tell, there is no pattern, or as stated, consistency...
