Okay, it's something like that that can actually make me occasionally (only occasionally

) want to use Firefox rather than Opera - or at least both.
I just tried installing PicLens (I do have FF installed for site testing), and it is indeed pretty damn cool. Too bad it only actually supports one site I use on a regular basis, DeviantArt - so until they add support for all my favourite porn paysites

, it's probably not likely to make me want to load up FF on a regular basis, no matter how neat the PicLens features are.
Edit: Okay, this thing goes so well together with DeviantArt (particularly since I actually feel they have a somewhat cumbersome site design in certain areas) that I may actually end up using Firefox when I visit that site

.
