BREAKING CHANGES The add-on will now officially support only versions of Firefox that are equal or more recent that the current Extended Support Release (ESR). As of this release, that means versions 115.x and above are supported. Additionally, a lot of work has been done on the internals of the add-on to try and fix (or at least improve) some of the issues introduced with the 3.x branch of the add-on (and themselves related to the internal bookmarking changes that happened back then in Firefox). While this should provide a better user experience, it also means the internal logic to identify which bookmarks to process and how has changed significantly, and this is made explicit via the major version number.

update minimum Firefox version to current ESR branch (87b862e)
refactoring of the code to prevent processing bookmark that should not be (and re-organization of the add-on's structure) (725213f)
