Need to turn off "This Connection is Untrusted" blocking.
I don't know what happened, but lately, Firefox has become unusable. I can't even get Google maps to work, and it's all because of the following warning:
=
This Connection is Untrusted
You have asked Firefox to connect securely to maps.google.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
If you understand what's going on, you can tell Firefox to start trusting this site's identification. Even if you trust the site, this error could mean that someone is tampering with your connection.
Don't add an exception unless you know there's a good reason why this site doesn't use trusted identification.

Untrusted?? REALLY?? maps.google.com is untrusted!?! Oh, and support.mozilla.org is ALSO untrusted? I'm using Chrome to post this because in the case of support.mozilla.org, there IS no option that allows me onto the site.
Pretty much every site I go to has this problem and Firefox is now all but unusable to me. And I'm on a corporate machine, so it's not like I have a lot of options here. And it's not our corporate network, because only a few of us have this problem.
How do I Firefox to work again, and disable this 'feature'?
Thanks

unfortunately the fiddler2 issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.

afterwards, run a full scan of your system with different security tools like the free version of malwarebytes & adwcleaner.

hello, first please make sure that the date & time is set correctly on your system.
if this doesn't solve the issue (or it is already set properly), could you tell us which error code is shown under technical details on the error message and when you inspect the certificate which issuer information it does contain (see screenshot)?
"This Connection is Untrusted" error message appears - What to do
Same here, I need this block stopped. I sent a "ask a question" request but have so far been ignored. My error code for trying to get to services.addons.mozilla.org and various other sites is (Error code: sec_error_unknown_issuer). Please instruct me on how to eliminate this problem. I cannot give you a screenshot as it will not let me add add-ons.

which issuer information do you get when you attempt to create an exception and view the certificate (as it's shown in the screenshot)?
Alright, this one is for maps.google.com. Issued to common name= maps.google.com organization= DO-NOT-TRUST organization unit= created by http://www.fiddler2.com issued by common name= DO_NOT_TRUST_fiddlerRoot organization= DO_NOT_TRUST organization unit= created by http://www.fiddler2.com
