Firefox is reporting ssl certificates having the wrong site name. Clicking on advanced shows that it's looking at the certificate for a different site.

Posted

After Firefox has been running for a day or so, I get SSL certificate errors saying the the certificate has the wrong site name. Clicking on Advanced show that FF has retrieved the wrong certificate. Instead of xyz.com, it'll gotten abc.com.

As an example, I was on notalwaysright.com, and it happened when I went to another page on the same site! The site it showed in the "valid names" bit, was a totally different site, but one that is accessed by a lot of sites.

Restarting Firefox usually fixes they problem, but it's been going on for a year or so.

It looks like Firefox is losing track of a pointer or an index or some such.

Then that would be a site certificate problem all browser uses a registered certificate to verify that the site matches and if doesn't then it doesn't load. So you will have to contact the site and tell them about the problem.

You can check the connection settings.

  • Options/Preferences -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":


Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

This is not a reproducible at will error. It's one that happens when firefox has been running for days.

It is *not* an error with the site's certificate. Otherwise, restarting Firefox wouldn't make the error go away.

Again, When I click on the "advanced" button, what firefox shows is a quite valid certificate, but not for the site I'm connecting to.

Instead, it's for a site that may be associated with the page (tracking cookies, etc). One frequent "wrong site is "aikhamai.net" (spelling almost certainly wrong)

I'll try to get some screen shots next time it happens.

But trust me, this *is* a firefox error, not a site error. Remember, in my initial message I noted that it occured when going to a different page on the same site. And that restarting firefox made the error go away.

Also note that rebooting the system is *not* an option because that will cause me to have to take several *days* to get certain things back to where they were before the reboot.

... "One frequent 'wrong site' is 'aikhamai.net' (spelling almost certainly wrong)"

... perhaps akamai.net? That would be very plausible, since they host a lot of third-party sites' inner-workings.

I remember having a similar problem that was driving me to reboot every night. (Sadly, I don't remember the 'silver bullet' that resolved it, but I think it was indeed third-party code with bugs, and it took a lot of detective work.)

Ok, this time I got lucky(?). I'd just rebooted from the monthly win 7 updates, and firefox had only been running a few minutes.

I hit refresh to update the page (my reading page on dreamwidth) and I got the error.

attached is a screenshot.

It says that kengr.dreamwidth.org is using a bad certificate.But it's displaying info for a certificate for pantheon.

As soon as I got the screenshot, I closed firefox and restarted. And this time hitting refresh on the page worked. Thus proving that's not at all likely to be the *site* serving a bad certificate, but rather firefox getting confused.

Note this has been happening for a year or so. Practically since FF started checking this. :-(

Does it make any difference if you reload the page bypassing the cache, either:

  • Ctrl+Shift+r
  • Shift+click the reload button on the toolbar
  • Ctrl+F5

Nope. Finally got a chance to try and it didn't help.

I did confirm that the problem is firefox losing track of things. This time, I'd clicked on a link in a pinned tab that was going to open a new tab for a story on NPR.

Then I switched to another pinned tab to refresh my dreamwidth reading page. I got the insecure site error and when I clicked for more info, it showed that the certificate was only valid for a bunch of .npr.org domains.

So I'd say that proves that the problem is firefox getting confused about which certificates go with which tab wouldn't you?
