When organizing the bookmarks in my Firefox browser I had a folder highlighted and hit
Delete by mistake. How can I recover the folder?
NOTE: It's too late to hit
Control + Z, and the bookmarked sites aren't in my history anymore.
From this discussion on the Firefox forums:
[...] you can restore the bookmarks from a JSON backup in the bookmarkbackups folder.
- Bookmarks > Show All Bookmarks > Import & Backup > Restore
This will replace all current bookmarks and you lose bookmarks that were added since that backup was created. See:
In that case, you need to export the current bookmarks to an HTML file before doing the restore and import that HTML file after you have restored the JSON backup.
