A nice extension very handy for comic strip sites (or even forums where people don’t know how to properly rotate and image before they post it). Once installed, simply right-click the image and select Rotate Image (CW) or Rotate Image (CCW) from the context menu.
Rotate Image is 37 KB works with Firefox 1.5-4 and does require you to accept an EULA.
Great Extension!!!! Wish I’d had it years ago!
