<p>Sorry, I missed that before. The other file you might rename is the icons file, <strong>favicons.sqlite</strong> (this article mentions deleting them, but I generally prefer to rename just in case one needs to roll back the change): <a href="/en-US/kb/fix-bookmarks-and-history-will-not-be-functional" rel="nofollow">Fix "The bookmarks and history system will not be functional" error message</a>.

</p><p>1. I still get the following when I first load Firefox: “The bookmarks and history system will not be functional because one of Firefox’s files is in use by another application. Some security software can cause this problem.”
I should note that I use McAfee and have been using DuckDuckGo as my search program.
</p><p>2. When I try to add a bookmark using the star in the URL box I get no response.
</p><p>3. I still cannot get the backup file to work. When I try to restore from a backup file (I’ve tried various ones with different dates) I always get this message: “Unable to process the backup file.”
</p><p>4. After it took the various steps you recommended (including renaming the places.sqlite file) I reran the Verify Integrity for the Places database and still got this:

- Unable to invalidate caches

</p>It might be necessary to remove the Places database, but as a starting point, perhaps it would help 2020-07-06T00:15:08-07:00jscher2000https://support.mozilla.org/en-US/questions/1293808#answer-1330424<p>It might be necessary to remove the Places database, but as a starting point, perhaps it would help to remove two temporary files. Here's how:
</p><p>Open your current Firefox settings (AKA Firefox profile) folder using either
</p>
<ul><li> "3-bar" menu button &gt; "?" Help &gt; Troubleshooting Information
</li><li> (menu bar) Help &gt; Troubleshooting Information
</li><li> type or paste <strong>about:support</strong> in the address bar and press Enter
</li></ul>
<p>In the first table on the page, on the Profile Folder row, click the "Open Folder" button. This should launch a new window listing various files and folders in Windows Explorer.
</p><p>Leaving that window open, switch back to Firefox and Exit, either:
</p>
<ul><li> "3-bar" menu button &gt; Exit
</li><li> (menu bar) File &gt; Exit
</li></ul>
<p>Pause while Firefox finishes its cleanup, then if you find these two files, delete them and start Firefox again to see whether it helps:
</p>
<ul><li> places.sqlite-shm
</li><li> places.sqlite-wal
</li></ul>
<p>If you run Verify Integrity after that, does it get further in the process?
</p><p><em>If those files do not exist or removing them does not help:</em>
</p><p>You can rename the Places database and see whether that resolves the issue (again, while Firefox is not running):
</p><p>Right-click <strong>places.sqlite</strong>, click Rename, then add OLD so the name is <strong>placesOLD.sqlite</strong>
</p><p>Firefox should start up with no browsing/download history, but should rebuild bookmarks from one of the automatic backup files. Did that work?
</p>Thank you for your reply.
I did restart the computer and the problem was not solved.

</p>Have you already tried a normal shutdown and restart of Windows to try to free up file locks?
After 2020-07-05T09:49:41-07:00jscher2000https://support.mozilla.org/en-US/questions/1293808#answer-1330300<p>Have you already tried a normal shutdown and restart of Windows to try to free up file locks?
</p><p>After that, if problems continue, could you let us know what you get when you run the "Verify Integrity" function. That's here:
</p><p>Open Firefox's Troubleshooting Information page using any of these methods:
</p>
<ul><li> "3-bar" menu button &gt; "?" Help &gt; Troubleshooting Information
</li><li> (menu bar) Help &gt; Troubleshooting Information
</li><li> type or paste <strong>about:support</strong> in the address bar and press Enter
</li></ul>
<p>Near the bottom, there is a section titled <strong>Places Database</strong> -- that's the file which stores history and bookmarks. Click the button labeled <strong>Verify Integrity</strong>. There may be a 10-15 second delay before results appear.
</p><p>If all is well, the report that appears below the button should start with:
</p><pre>&gt; Task: checkIntegrity
+ The places.sqlite database is sane
+ The favicons.sqlite database is sane
</pre>
<p>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.
