Went on the internet on Friday but a box appeared saying firefox could not verify web page and somebody could be trying to impersinate the web page this was my home page it gave me two options the first was get me out of here or that I understood the risks and to continue I clicked the latter and my home page came up this box continued to appear on each occasion I tried to acess any web pages but when I tried to acess Facebook the box only gave me the option of get me out of here it also did this when I tried to acess Mozilla Firefox to see whether there was a problem with the browser I tried to reinstall the browser but the problem persisted I finally got round the problem by reinstalling my computer to an earlier time before I did this I also have the option for Google chrome on my computer and this browser worked fine Facebook etc I prefere Firefox but although the warning box hasn't materialised since I reset my computer Firefox has become unstable where it has frozen on a web page and the only way I can get out is to start the task manager and end the programme even though the task manager is saying that the page is still working correctly but after I have ended the running of the programme it will not reload the firefox browser but again google chrome is fine I have to restart the computer to fix this problem any ideas thanks.

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
  • Make sure that you do not exceed the maximum size of 1 MB

Check the date and time and time zone 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.
