July 31, 2026. I just downloaded this extension (v1.5 for Firefox) and for me it's perfect. I have a bookmark folder that was originally set up as a place to store links to articles that were loosely related to a single topic. As time went by I ended up dumping in more and more articles connected to the original topic, but these sub-topics now are about 50% of the over 500 bookmarks. This extension makes it super easy to move bookmarks from one folder to another, just what the doctor ordered. I recommend this extension 10/10. Thanks
