Awesome add-on / Firefox 20 issue Noté 5 sur 5 étoiles
This is a must have for me, and after going to Firefox 20 the save image gesture wasn't working, saying "Starting point of gesture is not on an image". I disabled all add-ons and started enabling one by one to find the root cause.
In my case I got it working again by removing Add-on Compatibility Reporter, and Evernote Web Clipper. It seems like even if I just leave them disabled the problem continues, so I removed them for good.
