</p><p>Initially it looked as if a large number of users may be getting this problem but at the moment we do not see many reports maybe the problem was an infrastructure problem, as some of the techies suspected, and someone has silently fixed it.

<p>Hi heraclitus,
</p><p>What we are trying to investigate is the cases where this error message is being generated by Firefox. Firefox generates the popup after five or more background updates fail because of a certificate problem
</p><p>What we are really after is the <strong>error console</strong> messages a relating to <strong>certificates</strong> both
</p>
<ul><li> immediately after the popup message has been seen
</li></ul>
<ul><li> <strong>OR</strong> any certificate related error message immediately after you have tried to manually update firefox - to check that <strong>please</strong> do as follows:
</li></ul>
<ul><li><ol><li> open the error console for instance using <strong>Ctrl + Shift + J</strong> or <br> Firefox button -&gt; Web Developer -&gt; Error Console
</li><li> clear the error messages using the clear icon
</li><li> make a note of you version of firefox then attempt to manually update firefox using <br> Firefox button -&gt; Help -&gt; About Firefox - Check for updates
</li><li> then reopen the error console and copy and paste any new error messages <br>(you should not have many if you just cleared them) <br> we are particularly interested in messages mentioning certificates
</li></ol>

At the time I received this error message, my computer was idle (and I was not trying to update Firefox, since I already have 4.0.1. installed.) The bottom of the error message had the Firefox Web address to go to in order to update. So, just to see what would happen, I clicked on download the update. And Firefox went through all the update and installation steps--just as if I didn't have 4.0.1. (yet I did have 4.0.1. installed). What do you make of that??
