</p><p>Usually Firefox only covers the Taskbar in full screen modes, so if a regular "maximized" window covers the Taskbar, Firefox may have stored corrupted data for the screen height. Here's what we usually suggest in that case: rename the file and have Firefox rebuild it. 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 File 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 right-click <strong>xulstore.json</strong> and click Rename, then edit the name to something like <strong>xulstoreOLD.json</strong> and press Enter or click away to complete the edit.
</p><p>Start Firefox back up again. Do windows display normally again?
</p><p><em>That mini-reset may hide the menu bar and bookmarks toolbar.</em> You can use one of these methods to show the toolbar list and select the desired bars there:
</p>
<ul><li> right-click (on Mac Ctrl+click) a blank spot on the tab bar (or the "+" button)
</li><li> (menu bar) View &gt; Toolbars<br><em>On Windows, tap the Alt key to activate the menu bar temporarily.</em>
</li><li> in Customize mode &gt; Toolbars button (see: <a href="/en-US/kb/customize-firefox-controls-buttons-and-toolbars" rel="nofollow">Customize Firefox controls, buttons and toolbars</a>)
</li></ul>
<p>To turn on the Bookmarks Toolbar or Menu Bar, click it on the list.
