Mozilla won't let me log-in to my own account. Can't notify every website that they are out of date. I see this as a Mozilla problem.

Just downloaded Windows ten and it seemed OK with Firefox and Thunderbird until this problem. Mozilla--call me NOW +++ +++ ++++

If You don't call I drop Firefox and go with Explorer...


edit: removed phone# from public and spambots. Sorry but nobody here or from Mozilla does one on one phone support.

Hi greyfox73plus, the error page typically shows a code in parentheses (separated_with_underscore_characters). Sometimes you need to expand a Technical Details section to find the code. Could you post the one you're getting?

Here's one, for example:

The most common reason for getting (sec_error_bad_signature) on numerous sites seems to be the Avast Web Shield. Web Shield intercepts your browsing and filters it, but to filter secure sites, it presents "fake" certificates to Firefox.

To test this theory, try turning off scanning of encrypted sites. I saw these steps in another post:

  1. Open the Avast dashboard on the affected system.
  2. Select Settings from the left sidebar menu.
  3. Switch to Active Protection.
  4. Click on Customize next to Web Shield.
  5. Uncheck the "Enable HTTPS Scanning" option and click ok

If that resolves the issue, but you prefer to filter encrypted communications, you may need to import the Avast! signing certficate into Firefox's Certificate Manager, Authorities tab.

You can check the date and time and time zone in the clock on your computer: (double) click the clock icon on the Windows Taskbar.

If you can't inspect the certificate via "I Understand the Risks" then try this:

Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:

  • chrome://pippki/content/exceptionDialog.xul

In the location field of this window type or paste the URL of the website.

  • retrieve the certificate via the "Get certificate" button
  • click the "View..." button to inspect the certificate in the Certificate Viewer

You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then you can attach a screenshot that shows the certificate viewer.

After installing Windows Ten the browser slowly began to cripple my use of Firefox. Eventually, every time I try to navigate through a website to purchase, the Secure Connection Failed message appears. This is obviously an inadvertent or deliberate oversight by one or both vendors. Microsoft and Firefox need to resolve this fast.

In order to continue to be productive I have been forced to use Internet Explorer as a browser. This is most likely what Microsoft has hoped would happen.

This might be an issue with Microsoft Family Safety.

Ta Da! I think the uncheck box did the trick. Can't be sure all at once but so far no refusals to load a page. The speed of transfer/loading has also gone up.

How about how to have my Desktop display at start instead of the tiles of the windows ten? I know I can find most desktop items under another icon at the bottom left of the start tile set, but I also have frequently used word docs shortcuts there also.

Thanks to the responders for helping on this one!!

It's good to hear Firefox is working again. As for starting Windows 10 up directly to the desktop, I think that would be something you might find in a web search... for example: windows 10 boot to desktop - Google Search
