FAQ

• How does it work on thumbnail galleries?
  This addon downloads the image you directly interact with, i.e. the thumbnail. This is an unfortunately but deliberately omitted feature. Most browsers download link targets when alt-clicking on links, and most thumbnail galleries link each thumbnail to its full size source. Therefore, you do not actually need an addon to download most thumbnail galliers. For more complex galleries, addons dedicated to this purpose exist. You could also install Copy Selected Links and use a download manager.

The Options screen will automatically open after add-on updates if they force a change to any of your settings.

Please rate/review/donate! :)
A lot of time and work goes into creating my addons, and making changes or troubleshooting issues for users. This particular addon has cost hundreds of hours by now. Any donations are greatly appreciated.

Cross-browser
Please note that not all features work the same (or at all) as WebExtension support in browsers is not perfect yet.

Problem, bug, broken, question, request?
Please use the linked support site or email for all non-review communication. AMO policy protects both users and developers by demanding certain quality standards from addons as well as reviews. Severely disfunctional addons are not published. Reviews and ratings must consider the entire addon, set reasonable expectations, and be timeless: a bad rating focusing solely on a systemic bug or on a problem not suffered by other users will stay long after the issue is resolved. AMO also gives extremely limited communication abilities, so contacting me properly will get your issue resolved much better and faster.
