I lost 6 years of bookmarks!!

I have owned my Mac Book Pro since 2014 and I inadvertently re-installed Firefox without knowing a new profile would be created. I am not able to load my old profile into the new one. I can see the "old Firefox data" folder and have tried everything Firefox has to fix this but nothing is working. I have lost 6 years of bookmarks!

Anything other tricks to fix this? Thanks!

Just to make sure, have you read this document?

Thank you for this information. I have tried everything mentioned and when I try to restore bookmarks using my old firefox data, "bookmarkbackups" file, they are still not there. Am I doing something incorrectly? Or are they stored somewhere else in Firefox?

Could you let us know what you get when you run the "Verify Integrity" function. That's here:

Open Firefox's Troubleshooting Information page using any of these methods:

  • "3-bar" menu button > "?" Help > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Return

Near the bottom, there is a section titled Places Database -- that's the file which stores history and bookmarks. Click the button labeled Verify Integrity. There may be a 10-15 second delay before results appear.

If all is well, the report that appears below the button should start with:

> Task: checkIntegrity
+ The places.sqlite database is sane
+ The favicons.sqlite database is sane

Does yours say that, or something else? You can select and copy the report, and then paste it into a reply for review and comment.

This is what I got after hitting "verify integrity".

Thanks, that all sounds good, so it's a mystery to me why the bookmark backup file won't restore.

Just to review what you're doing:

(A) Open the Library window (Command+Shift+b)

(B) On the Import and Backup menu (icon may be a star with circling arrows, or up and down arrows). click Restore

  • If an earlier date is available, pick it from the menu and see whether it gets restored.
  • If no earlier date is available, click Choose File and point Firefox to the Old Firefox Data folder, into your old profile folder, into the bookmarkbackups folder, and load one of the dated backups. The file name has the number of items (bookmarks + folders) coded into it. For example, 425 in this case:


After that, the old bookmarks don't show up?

Correct. No bookmarks show up after doing what you said above. Are they gone?

I have a tool that converts a .jsonlz4 backup file to an HTML-format "export" file. This allows you to see what is in the file, and then you also can use the bookmark "Import" feature to see whether that works better than the "Restore" feature.

Here's the page:

After dropping your .jsonlz4 file on the page, click Export HTML. You can save the file anywhere convenient.

This is a real shot in the dark.

Do you use Time Machine to create backups? If so, you could try restoring the Old Firefox Data folder from a backup prior to the date you reinstalled Firefox and then perform the recovery instructions again. I have no idea if this will work never having tried it.

Does this make sense, Jscher2000?

Hi OBW47, as a Windows user, I'm not sure what Time Machine stores.

Hmm, that sound like a conversion of a fresh new file. If you check your Old Firefox Data folder again, can you find one old enough to be from before the change, and how many items does it says it contains?
