Here's a two of my selection of some lesser known (and some well known) firefox extensions that make using the internet a little more interesting. I'll post a couple more depending on what the interest is like. EXIF data / http://ted.mielczarek.org/code/mozilla/fxif/ Allows you to quickly check whether a photo contains EXIF data, so that you can determine whether it may contain an EXIF thumbnail. EXIF thumbnails often go unchecked, and usually contain the original and unedited/cropped version of the photo (which can then be extracted via various windows applications or jhead on linux/unix systems, do a google search). For an example of how this can churn up interesting data, read about what happened to Catherine Schwartz of techtv a couple of years ago: "Schwartz was the subject of a stir in the Internet community when it was discovered that at least two cropped photographs of herself she had posted on her personal blog contained hidden EXIF thumbnail images of herself clearly showing her bared breasts" - http://en.wikipedia.org/wiki/Catherine_Schwartz Tamper Data / https://addons.mozilla.org/firefox/966/ This is an extremely useful extension for performing security audits on your own web application, and pulling pranks on webmaster friends. I've used this on more than one occasion to "goatse" a comrade (note: i do not endorse such action). It allows you to modify and POST/GET data before it is posted to the target page.
Thanks for these The first one could be interesting, just need to restart firefox and give it a go Cheers, David
http://www.xs4all.nl/~jlpoutre/BoT/Javascript/ExifThumbs/ is a handy greasemonkey script that'll extract the EXIF thumbnails for images in a page or directory. I've not had much luck getting it to extract from viewing an image on its own though.
