This is because history sync destroys the frequent site selector. The most common sites I visit on my mobile device are very different from my primary computer.<br>
<br>
As an example, here's my most popular list on my phone:<br>
<br>
<a href="http://npr.org" rel="noreferrer" target="_blank">npr.org</a><br>
Johnstown <a href="http://weather.gov" rel="noreferrer" target="_blank">weather.gov</a><br>
failblog<br>
<br>
And the newtab tiles on desktop:<br>
<a href="http://mail.google.com" rel="noreferrer" target="_blank">mail.google.com</a><br>
<a href="http://twitter.com" rel="noreferrer" target="_blank">twitter.com</a><br>
<a href="http://washingtonpost.com" rel="noreferrer" target="_blank">washingtonpost.com</a><br>

<a href="http://bugzilla.mozilla.org" rel="noreferrer" target="_blank">bugzilla.mozilla.org</a><br>
<br>
I suggest that we explore ways to fix this. Either don't sync history by default on mobile devices, or have a better frecency algorithm which weights based on "this device" visits rather than all visits (or at least weights them more heavily).<br>
