How do I resolve "ffupdate.engine.conduit-services.com Invalid Security Certificate" Error when checking for updates?

That wouldn't affect all add-ons, like those hosted at and updated from the official Addons.Mozilla.com website, only the add-ons getting updates from Conduit.

Looks like they aren't following the rules for "certificates".

ffupdate.engine.conduit-services.com uses an invalid security certificate.

The certificate is only valid for the following names:

 *.conduit-services.com , conduit-services.com  

(Error code: ssl_error_bad_cert_domain)

Thank you for your prompt reply. Unfortunately I am still at somewhat of a loss as to how to proceed.

Please be aware that I am using the blanket "check for updates" method. I also have a lot of extensions.

1. My impression was that the add-ons (extensions) are updated sequentially until the first one that depends on conduit services is encountered, at which point the aforementioned modal error dialog is raised, which aborts the entire process regardless of the manner in which the dialog is dismissed (e.g. Cancel, OK...) . Is this correct?

2. How do I determine which add-ons are using conduit-services so I can, if necessary, disable or uninstall the (hopefully few) that depend on conduit-services?

3. Can I uninstall the problematic ones and re-install them from Addons.Mozilla.com?

1. I can't say if it is sequential or not, I have never seen a message like that myself when doing add-on update checks - but I have seen other messages, like the update server not using a secure HTTPS address after that became a requirement for updates.

Plus, I have never used anything from Conduit - the founder of that company has a shady past with different internet companies puling all dorts of "stuff", IMO.  And all Conduit add-ons were removed and banned from the official add-ons website a few years ago because of their "antics" and major user uproar at the time - just recently have we seen a few return.

2. Right-click individual addons and use Visit Homepage' to see if that feature is being used as intended and where it takes you. Or use Find Update and see if that triggers that message, to discover which extensions are fro Conduit.

3. IMO, you are better off updating each extension one at a time with Find Update, as I mentioned above.

My third question was: "Can I uninstall the problematic ones and re-install them from Addons.Mozilla.com?"

You answered: "IMO, you are better off updating each extension one at a time with Find Update, as I mentioned above."

But I wasn't asking whether I should perform the updates individually or collectively. Hint: If every Firefox extension can be downloaded from Addons.Mozilla.com, then the answer is "Yes" with a probability of 1; otherwise, it is "Possibly" with a probability equal to: 1 - s , where s is your subjective estimate of the percentage, expressed as a decimal, of Firefox 5.0.1 compatible extensions that may only be downloaded from unofficial sites, i.e., sites other than Addons.Mozilla.com.

Yes, uninstalling and reinstalling those extensions that can "only" be obtained from AMO will work.

Hint: This is why I rarely answer postings from Mac users, they always find something to complain about or nit-pick the answer they are given, and seem to be unable to do it without making it sound like they are insulting the person providing support with crap like Hint. I was offering what I thought was a quicker method of achieving the same objective - getting an updated version of the extensions available from AMO using a built-in that you may have been aware of, unless you don't even have a 2-button mouse. I doubt that you thought through my answer to #3 thoroughly or you would have done that instead of criticizing my answer and talking down to me like I am stupid - pure arrogance. Makes me reconsider the amount of time I volunteer here to help rude people.

Correction: It now occurs to me that the general solution I outlined is trumped by your specific knowledge regarding conduit-services.com; so s becomes: your subjective estimate of the percentage, expressed as a decimal, of Firefox 5.0.1 compatible extensions that may only be downloaded from http://ffupdate.engine.conduit-services.com. I also forgot to multiply the probabilities, so 1-s becomes 1-s^n, where the number of extensions I have installed that currently attempt to update themselves from http://ffupdate.engine.conduit-services.com. Of course, since neither of us knows n at this point, you need only produce s.

To recap, the point of all this is so I can decide whether it is worthwhile to search Addons.Mozilla.com for the problematic extensions . Your remark, "just recently have we seen a few return" is relevant but too vague to be of use. Would you care to elaborate?

I was simply trying to clear up your misinterpretation of my third question, so that I could benefit from your answer. If I thought you were stupid, I would have simply abandoned the thread. I have better things to do than joining internet forums in order to upset remote strangers under the pretense of a request for technical assistance!
