This really helped me with consolidating all of my data from Edge and Chrome to Firefox :)

had several all-but-one functions, ugly, but worked. just what i needed, without all the faff.

perhaps dated code, did not delete empty directories, however. found them, but then something couldn't get through perhaps windows protections,.. not sure. sat there at 0% complete, no errors, no pop-ups, no consent-on-the-desktop, etc. Might need a few code updates, but the CORE NEED, of being able to combine future searches for a individual bookmark regardless of where AMONGST your mess of directories, after you've removed duplicates,.. for a minimal-effort combination of the two,.. i could do. Good enough. Thanks!

Чудове розширення для чищення дублікатів закладок, що виникають після усіляких синхронізацій в нашому недолугому Firefox. Підтримка української.

Take it Down

Very helpful

worked well. thanks dev
Firefox should have this as feature.

Does not find duplicates if they are restored from a backup (via a regular browser tool). Or a problem with the browser version. 114.0.1.

Does the exact thing it says it does, provides easy macros to select all but one of each duplicated bookmark then erases them all. It does all this on its own page preventing the "popup goes away with all your work" problem. Little more could I ask for from an extension of this type.

This extension has been a lifesaver after a particular synchronization app duplicated my bookmarks in exponential numbers. There do, however seem to be a couple of glitches. I'll forward more detail to the developer...
