Unofficial extension of JustDeleteMe for Firefox-based browsers.
This extension is new, there may be some minor quirks or bugs. If you find any, create an issue on this GitHub repository.
Since this uses manifest v2, it is currently not compatible with Chromium-based browsers, but there is already an extension for that by Mike Rogers.
