Firefox did not open Facebook, Twitter
Firefox did not open Facebook, Twitter. If go to You Tube using google apps it did not open You Tube but it open if type the url in address bar. It opens other websites. (3 weeks before It was working fine) - I login as standard user.
Error
This Connection is Untrusted You have asked Firefox to connect securely to twitter.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.
twitter.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)
If i login as admin then Firefox opens all websites. I uninstall and restart the PC (windows 8.1) then installed the Firefox but no use. I tried some methods specified in forum but that did not help me. Chrome is working fine. But i want to use FireFox for all activities.
I have McAfee, I ran it but it did not detect any viruses.

Hello,
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:
- Click the menu button
and click History button, and then Clear Recent History... .
- Under "Time range to clear", select "Everything".
- Now, click the arrow next to Details to toggle the Details list active.
- From the details list, check Cache and Cookies and uncheck everything else.
- Now click the Clear now button.
Further information can be found in the Clear your cache, history and other personal information in Firefox article.
Did this fix your problems? Please report back to us!
Thank you.
DB, I clear all cookies and cache. But still Facebook, twitter are not working. Getting the same error.
Thanks
Check the date and time in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
Check out why the site is untrusted and click "Technical Details to expand this section.
If the certificate is not trusted because no issuer chain was provided (sec_error_unknown_issuer) then see if you can install this intermediate certificate from another source.
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 of the certificate.
You can see more Details like intermediate certificates that are used in the Details pane.
If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
- Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
- Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.
Cor-el, I get (Error code: sec_error_unknown_issuer) I don't get "I Understand the Risks". so right click but i don't get This Frame: Open Frame in New Tab". Or am i missing something?
