This started a couple of months ago and pops up for just about every site, including Google, Macy's, DSW, Outlook.com, etc. These are all regularly visited sites so there should be no problem. There is no problem if I use Chrome or Internet Explorer.
Searching for resolution has indicated the problem can be fixed by correcting the date/time or that it is due to issues with BitDefender.
Neither is my problem. My clock & date are connected to our network and are correctly displayed. There is no BitDefender installed on my machine.
Disabling the certificate validation is also recommended as a solution however, the problem still continued after following the steps to disable. I have also removed the program entirely from my computer and reinstalled it. Still running into the same issue.
Does anyone have a way to truly fix this ?
Thanks

I had this same problem and it started yesterday (6/22/2013) when my computer did an auto-update: "Mozilla FireFox 30.0 (x86 en-US)". I think that the update didn't download properly, or it was a corrupt file or something. I tried a bunch of things but most of the stuff I was finding on-line didn't work.
Uninstalling FireFox and re-installing the most recent version fixed the problem.
Go to your Control Panel; uninstall FireFox, then go to the FireFox website in another browser and re-install. That worked for me!
So here's the issue how do you determine whether it's just your system, something in your network, something upstream? Application specific seeminly...
Is this problem limited to this program for you only or to everyone in the network? You could just try clearing/deleting your profile whether it's just profile corruption?
If it's network wide it's quite often linked to a network/server web proxy which isn't quite working properly (as indicated in another answer. Contact the vendor your local admin for help in dealing with it. At times, it's just something you have to accept. At others they may be willing to create exceptions for you on the proxy itself or via proxy settings configuration files which can be updated en-masse.
Did it happen after you updated your version of Firefox? I remember it has a history of paranoia compared with other browsers but after one particular update it went crazy with regards to these certificate problems.
If they aren't related to these issues the obvious question is whether or not there has been a security breach in which case you should be running diagnostic scans (it doesn't seem to be the case it's limited to one program though).
What fixed it for me was going to:
Internet Options >> Connections >> LAN settings >> Unchecking the third option "Use a proxy server for your LAN" (here's a screenshot to help:
I've just had my laptop back from having motherboard replaced & wouldn't trust websites. Computer date & time were out, so got the system to update time/date from the internet. Everything back to normal.
Hope this helps
