I migrated my bookmarks from Chrome when switching over to Firefox. But none of the favicons of the bookmarks were getting loaded, unless I load the bookmark manually. I had too many bookmarks to do this manually. Thankfully, I came across this add on. It fully automated the process for me and now I have favicons on all my bookmarks. The other features are useful too, but they were not my main focus. I deducted a start because in the duplicate finder, it showed the location of only one. I wanted to see all locations to decide which ones to keep and which ones to delete.
