URL Flipper is a Firefox extension that allows you to easily increment or decrement a portion of a URL without having to manually edit the text in the Location Bar.

Yes, similar extensions do exist. First, there is Magpie, which was the extension that I was using before I wrote URL Flipper. URL Flipper was inspired by Magpie in the sense that it was modeled after Magpie and that it was written mostly to address a number of the bugs and shortcomings in Magpie's digit flipper tool. URL Flipper is also more fully-featured than Magpie. Finally, URL Flipper does not contain any of Magpie's media download tools, so it is designed for people who want a URL increment utility without the extra unrelated features.

Another tool that is similar in function is the Location Navigator extension. I had considered using this extension instead of writing my own, but I had wanted more functionality (such as the ability to handle non-decimal input or mixed alphanumeric input) and I wanted that functionality to be presented in a simpler, less complicated way. In some respects, Location Navigator is more fully-featured, with toolbar buttons and options dialogs, and in some respects, URL Flipper has more fully-featured, with more robust data type handling. URL Flipper was consciously designed to be more spartan in its presentation: there are no toolbar buttons (it is designed to be invoked by keyboard shortcuts) and there are no options dialogs. URL Flipper is small in size and has a lightweight code base. This may appeal to some people but not to others.
