Firefox Nightly keeps bugging me with "This Connection is Untrusted" on every single site I visit

Posted

So I am trying out the new FireFox Nightly, as it was suggested by a friend to me. Now I am liking it at first, but when I remove all my old FireFox stuff (completely uninstalled as there was alot of useless junk/plugins/data that I wanted gone) I am now getting this "This Connection is Untrusted" message on every single site I visit! It even says that the mozilla site is dangerous. So is there any way to disable these warnings?

Nightly is mainly for developers and testers. If you are a normal user, I suggest using Firefox.

Question owner

Normally I would, but FireFox's current stable release is not as good as chrome, so no real reason then. Nightly is faster and better than Chrome though, so I am playing around with it. I am just asking this question to see if it is possible to bypass the problem untill it is fixed, if not, I am a seasoned Alpha/Beta tester so I am used to hell breaking lose in things like this.

I would suggest clearing cache and cookies and resetting firefox.

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:


  1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
  2. Under "Time range to clear", select "Everything".
  3. Now, click the arrow next to Details to toggle the Details list active.
  4. From the details list, check Cache and Cookies and uncheck everything else.
  5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Hello Rykuu, also, check the time and date of your system, if the date and time on the computer are wrong then security certificates may not be valid.

which security software do you have (firewall or/and anti-virus)?


thank you

Question owner

I am using a firewall and a couple of antiviruses (windows 7 default, and Malewarebytes). I have told my time and date to auto adjust to the interent's time or something like that.

Disable firewall and antiviruses for a minute, and check it again, if the issue is not present then try to configure the firewall and antiviruses to allow firefox access.

thanks

Question owner

Ok, I did the firewall (didn't want to stop the routine scan of the anti-virus just yet) and it solved the problem. Any ideas on how to fix that without killing my firewall all the time?

When the question is, 'how do I stop the message?", thast means what it says. It is NOT the same as, what might cause the message? Or, how might be eliminate the cause of the message". The question is, how to control if, or if at all, when, these kinds of messages are thrown.

Check out why the site is untrusted (see the Technical details) and if this is caused by a missing intermediate certificate then see if you can install this intermediate certificate from another source.

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.

  • Click the link at the bottom of the error page: "I Understand the Risks"

Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".

  • Click the "View..." button and inspect the certificate and check who is the issuer.

You can see more Details like intermediate certificates that are used in the Details pane.
