Screenshot of the reported behavior

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:11.0) Gecko/20100101 Firefox/11.0
Build ID: 20120310193349

Steps to reproduce:

Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:17.0) Gecko/17.0 Firefox/17.0

Hi,

I'm using Firefox 17.0 on an up-to-date Ubuntu 12.04.1 LTS, and my
settings are to clear history/cache when Firefox closes. In these
conditions, about:newtab is supposed to display thumbnails of the most
visited websites of the current session (according to fixed bugs 744388
and 736724).

The behavior I observe is that about:newtab only displays the thumbnail
of the first visited website of the current session, in top-left
position. The eight other thumbnails remain blank (no text, no image).
Yet thumbnails are correctly generated and saved in the "thumbnails"
directory in my profile directory.

In the attached picture, I've opened www.omgubuntu.co.uk,
www.nytimes.com, boards.4chan.org/b, www.perdu.com, about:newtab in five
different tabs, in that order, in a new session, with all
addons/plugins/language packs deactivated. I've waited for each webpage
to load completely before opening the next one. None of these websites
uses HTTPS or Cache-Control: no-store/no-cache.


Actual results:

Only the first visited website gets a thumbnail in about:newtab, despite
thumbnails for all websites appearing in the "thumbnails" directory. The
same behavior occurs when starting Firefox in Safe Mode.


Expected results:

Unless I am mistaken, about:newtab should display thumbnails for the
four visited websites, not just the first one.

What can I do to help troubleshoot this behavior? I reported this bug on
Launchpad against Ubuntu's firefox package
(https://bugs.launchpad.net/bugs/1081123), but it doesn't get much
attention there.

Wrong computer. I'm talking about another computer, with:

> Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:17.0) Gecko/17.0
Firefox/17.0

I knew I should have used the unsimplified bug report form. Also,
changing component to Tabbed Browser.
