I have been accessing a Facebook app right along without any issues, and now suddenly Firefox is saying that the certificate is invalid and will not let me connect. The problem is that I am not being given the option to bypass the warning, all I get is the Get me out of here option. I have tried clering all histories, caches, etc. I have even gone so far as to uninstall Firefox, remove all personal settings, and reinstall it, and it still hasn't solved the problem. I have tried all the suggestions posted here, and they have not helped/
Some sites like Facebook have a setting to force a secure connection and that may not always work.
You can look at this link on how to disable forcing a secure connection in Facebook.
Does this problem occur when you follow a link or a bookmark, or only when you enter the URL into the address bar? In the address bar scenario, the autofill feature may direct you to a secure page where the site is not prepared for a secure connection. Try deleting the "s" from the https and see whether you can navigate into the site. If the site wants you to make a secure connection, it should use https where appropriate.
I have always used the secure browsing option when on Facebook, and up until now, have never had a problem. I did, however, try turning it off before I even posted my problem here. It had no effect. Also, as I mentioned here, Firefox is not even giving me the the option to ignore the warning and continue. All I get is the Get me out of here option.
This is standard Facebook music app, and one which I have been using without any problem for ages. The link is on every song posted on my timeline and in the app list on my homepage. No matter how I try to access it, Firefox refuses to allow the connection. even though it has always allowed it in the past.
Some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
You can see more Details like intermediate certificates that are used in the Details pane.
As I have said, there is no I understand the risks link at the bottom of the page as there normally is. All i get is the "Get me out of here"option. Furthermore, as I have also said; I have been using Facebook and Profile Song right along with no issue. This literally happened overnight, without making any changes, additions, deletions, from Firefox or Facebook. It quite literally was working perfectly when I went to bed, not working when I got up and has not worked since. Firefox does not see any certificates to add to the exception list. Again, i tried all of these things before posting here. This was my option of last resort.
Is there a general link to try the music app? A volunteer could take a look and see whether she or he could replicate the problem.
Hi - this is not a Facebook-related problem; the same thing is happening to me with the Austrian composers' rights association website (similar to ASCAP). I receive these warnings on a regular basis since many certificates in this region appear to be unknown to Firefox - but this is the first time that there's no "bypass" option. I recommend trying another browser.
Hi pyaeger, generally speaking, untrusted certificates should be rare. Firefox trusts certain root certificates and web servers are supposed to send a chain of certificates up to one of the trusted roots. If there is a certificate issuer in Europe that is not recognized by Firefox, can you indicate which one it is? Or could you provide a link to a couple of pages that generate(d) the errors?
