</p><p>To change what appears in the tab (after removing any problem extensions), you can use Firefox's about:config preferences editor.
</p><p>(1) In a new tab, type or paste <strong>about:config</strong> in the address bar and press Enter. Click the button promising to be careful.
</p><p>(2) In the filter box, type or paste <strong>newtab</strong> and pause while the list is filtered
</p><p>(3) Double-click the <strong>browser.newtab.url</strong> preference and enter the desired value:
</p><p><em>(i) Page thumbnails (default)</em>
</p><pre>browser.newtab.url = about:newtab
</pre>
<p><em>(ii) Blank tab</em>
</p><pre>browser.newtab.url = about:blank
</pre>
<p><em>(iii) Built-in Firefox home page</em>
</p><pre>browser.newtab.url = about:home
</pre>
<p><em>(iv) Any other page</em>
</p><pre>browser.newtab.url = full URL to the page
</pre>
<p>Press Ctrl+t to open a new tab and verify that it worked. Fixed?
