Hi Bill, sorry to hear about this problem. Did Firefox mention needing to create a new profile or perform a Refresh/Tune-up before this problem occurred? Any other major changes on your system? Is any other data missing?

As a starting point, could you check the steps in the following article: Recover lost or missing Bookmarks

I lost everything and I need the bookmarks to be resorted. My entire business is save in the bookmarks. This happened after the latest update with Windows 11

Is your Firefox like a blank slate, or does it seem to still have your other customizations?

One possible reason for Firefox to start up without some of all of your data is that a file was locked/inaccessible. Therefore, I always suggest starting with exiting/quitting Firefox and doing a normal system shutdown and restart to complete any pending updates and release any file locks.

Next, depending on the problem:

(A) Firefox doesn't have any of your data

Please try the steps in the first section of the following article: Recover lost or missing Bookmarks

(B) Firefox has some of your settings but bookmarks aren't working correctly

Let us know what you get when you run the "Verify Integrity" diagnosis and repair function. That's here:

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

• "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

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
> Task: invalidateCaches
+ The caches have been invalidated
> Task: checkCoherence
+ The database is coherent

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.

After that, the feature should report the number of bookmarks, which hopefully is well in excess of the 19-25 that come with a new install. You may need to scroll down to read the details for moz_bookmarks.

If the problem was after a major system update, do you see this folder:

C:\Windows.old

If you have that folder, let me know.
