Currently, Firefox doesn't have a visible Recycle Bin folder. The only way to restore a bookmark deleted earlier in your session is to use the "Undo" feature here: Library window > Organize menu > Undo You can open the Library window using either: * Ctrl+Shift+O as in Organizer * menu button > Bookmarks > Manage Bookmarks * (menu bar or Alt+B) Bookmarks > Manage Bookmarks ---- If this blind Undo feature isn't helpful, an alternative would be to convert one of your Firefox's automatic bookmark backups to a web page of clickable links that you could use to open tabs or right-click > Bookmark Link. I have a tool for that on my website here: https://www.jeffersonscher.com/ffu/bookbackreader.html To find your backup files: You can open your current Firefox settings (AKA Firefox profile) folder using either * "3-bar" menu button > Help > More Troubleshooting Information * (menu bar) Help > More Troubleshooting Information * type or paste '''about:support''' in the address bar and press Enter In the first table on the page, find the '''Profile Folder''' row and click the "Open Folder" button. This should launch Windows' File Explorer listing the contents of your current profile folder. Then double-click into the '''bookmarkbackups''' folder and check the file names. The pattern is: bookmarks-year-month-day_'''item-count'''_''gibberish''=.jsonlz4 If you see an older one that has a larger item count than your current file, that could be a good candidate for extraction. You may want to copy/paste it to your Desktop for easier access.
