HI, that is too bad when that happens, it is more than possible they are lost.

• https://support.mozilla.org/en-US/kb/recover-lost-or-missing-bookmarks

Bookmarks are in below in the Profile :

• bookmarks and history: places.sqlite
• bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder

Fyi for the future :

• https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Thank for the information. If I have the back up files from before the update but they are corrupted is there a way to restore them?

Hi, no not unless you can get something out of the places they are stored. If are in HTML drag it into a browser tab and see what is salvageable. If is in compressed java then your out of luck unless : If a jsonlz4 backup can't be imported restored because it has the same structural problem as the database, a user can try to fix it using the Check/Repair JSON button on this page:

Saving/backing up in both ways is good but as HTML you can at least do the above or shove it into a HTML Editor.

That going back and forth messed with them.

Hi almills425, if you haven't already, could you quickly make a safe backup of all your bookmark backup files? If Firefox comes across such old files in its regular folder, it might delete them.

HI jscher2000, how would I make a safe file of the bookmarks if they are all corrupted?

I meant your older .json or .jsonlz4 backup files. If they are in your active profile in the bookmarkbackups folder, Firefox will cycle them out.

Thank you all so much! I found a back up which I can place in the website above (https://www.jeffersonscher.com/res/bookbackreader.html) ad I can click links off of that to re-do all my bookmarks. I will strive to back up my bookmarks more often and save them in HTML files. Thank You All.
