Really excellent add-on!!!!

This is the one. This is it! After loosing helpful addons like URL flipper and Flashgot, somebody went out and brought the functionality back. Despite image hosting sites frequently thwarting this addon and the addon being unable to build galleries or at least search in a direction for pages that return something other than 404 or some other error, this little tool can get you to other image galleries if you're willing to flip far enough out in a direction. Thank you for making this. It's pretty nice to have again.

Long time user and like the addon a lot. What just changed from 0.0 to 0.1 besides going from "@license LGPL-3.0" to a custom-proprietary one? What exactly is going on with this project?

What, no 6th star I can give this add-on? It performs exactly as described. Its author was super helpful when I ran into an installation issue (See GitHub issue #3 for our correspondence about this). The issue is not one you are likely to encounter, and, after solving it with Roy, I now have access to all features of this very flexible add-on (plus its companion add-ons to optionally add "+" and "-" buttons in your toolbar). I can enable it (or not) to work in Private Windows, and it's default keystroke shortcuts Ctrl-Shift-Up Arrow and Down Arrow do not interfere with my other add-ons (Zoom Scheduler, Duck Duck Go Privacy, Duck Duck Go Search). I've been looking for a replacement for the ancient and perfect "URL Flipper" after updates to Firefox rendered it unusable. This one, URL-Incrementer, is the real deal and the way to go.

I've been using the "URL Flipper" extension a lot for many years, and was missing it ever since the change to WebExtensions. This is a great replacement! The only thing I find missing is separate increase/decrease buttons to add to the toolbar, but I understand that this may be due to restrictions imposed by Firefox and simply not possible anymore after the old extension APIs have been removed. The keyboard shortcuts, which are thankfully fully configurable, are a good replacement for now, though. Thank you to the developer!

Doesn't work with Firefox 71...

Works great! Thanks for creating it.
