I'm sorry to hear that you lost all your bookmarks! It can be frustrating when that happens unexpectedly. Here's what you can try to get them back: First, check if your bookmarks are stored in a backup. Go to "Library" in the Firefox menu, then click on "Restore." If there's a recent backup, you can restore your bookmarks from there. If not, try checking your bookmarks in "Show All Bookmarks" under the "Bookmarks" menu to see if they were accidentally moved to a different folder. If you still can't find them, you can try using a data recovery tool or a third-party bookmark manager extension to see if your bookmarks are recoverable. Remember to regularly back up your bookmarks to prevent future losses. I hope this helps, and let me know if you need any further assistance!

do you have any recommendations for any third party book managers that I can use?

Bookmarks are stored in your profile folder so reinstalling would make no difference. You should backup your bookmarks and your profile folder or the Mozilla folder containing it. Have you lost any other data such as settings and extensions?

You could try searching the add-ons site for alternative bookmark managers.

If you use Sync, best is to disconnect Sync temporarily during troubleshooting.

This could be a problem with the places.sqlite and favicons.sqlite files in the Firefox profile folder.

• use the "Places Database" -> "Verify Integrity" button on the "Help -> More Troubleshooting Information" (about:support) page

If errors are reported with "Verify Integrity", close and restart Firefox or reboot and retry.

If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder with Firefox closed. Firefox will rebuild places.sqlite and restore the bookmarks from the most recent JSON backup in the bookmarkbackups folder.

• keep a backup copy of places.sqlite in case a new places.sqlite database has to be created
• you lose the history when a new places.sqlite is created

You may have to restore an older bookmarks backup in the bookmarkbackups folder via the Bookmarks Manager (Library).
