<p>You can check for problems with the <b>places.sqlite</b> and <b>favicons.sqlite</b> files in the Firefox profile folder.
</p>
<ul><li>use "Verify Integrity" button on the "Help -&gt; Troubleshooting Information" (about:support) page
</li></ul>
<p>In case errors are reported with "Verify Integrity" close and restart Firefox and retry.
</p><p>If "Verify Integrity" cannot repair places.sqlite then remove all <b>places.sqlite</b> and <b>favicons.sqlite</b> files in the Firefox profile folder.
Firefox will rebuild places.sqlite and restore the bookmarks from a recent JSON backup in the bookmarkbackups folder.

<ul><li>keep a backup copy of places.sqlite in case a new places.sqlite database has to be created

<p>Maybe an Extension feature? What are your Extensions?
</p><p>What if you do this?: <strong>Menu &gt; Help &gt; Restart With Add-ons Disabled</strong>.
