Try looking for the bookmarks file itself.

I use linux, so I can't tell you its location in Windows (though I'm sure you can query online for this info).

In Linux you can find it in /home/[user]/.mozilla/firefox/mnbyxovr.default-release/ (At least on my machine)

The file name is places.sqlite

If you can't find it, check your trash bin. Maybe you can recover it.

HTH!

Hi coolmitch54, were there any other noticeable changes, such as different theme, different toolbar layout, different history, missing add-ons, etc.? That would yield different suggestions than only bookmarks being affected.

Access to Bookmarks

In case the problem is a toolbar or button missing:

• You can re-enable the horizontal bookmarks toolbar (normally appears below the main toolbar) using the "Toolbars" button in the Customize panel
• You can add the optional bookmarks menu button () by dragging it to the main toolbar in the Customize panel

Recovering from data loss

Firefox keeps approximately daily bookmark backups, so restoring one of those could help. That and other suggestions are collected in this article:

Recover lost or missing Bookmarks

However, if you can't add new bookmarks, either, there could be file damage. This article discusses that situation:

Fix "The bookmarks and history system will not be functional" error message

Are there backups available in the bookmarkbackups folder?

• Bookmarks -> Show All Bookmarks -> Import & Backup -> Restore

I didn't notice any changes after the update. I tried the Restore suggestion and it gave me a window that said unable to process backup file. Now what?? All of the bookmarks are still on my other computer. Is there a way to copy them onto my laptop, although they are much different. My laptop is my primary computer.

Hmm, not a good error message. 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 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

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 the result of the verify integrity function

That looks good.

It says there are 757 bookmark records (includes both bookmarks and folders in the count). Can you find them in an unexpected location if you try the "Library" window (Ctrl+Shift+b). Use the navigation pane on the left side to check each category:

• Bookmarks Toolbar
• Bookmarks Menu
• Other Bookmaks

OK, they show up under Bookmarks Menu. How do I get them back to the browser?

Never mind. They're back there. I'm not sure what I did but thank you for your help!! I was panicking there for a while!!

I guess I SHOULD say I don't know what YOU did but thanks!

Hi coolmitch54, the "Verify Integrity" function performs a bit of database maintenance, so that may have cleaned up some stray debris and sorted it out for you. It's great that nothing more dramatic was required.
