Hi Joan, have you seen any "untrusted connection" errors lately? Sometimes a site's style sheets do not load, and therefore the layout is unstyled, if the servers supplying those style sheets are untrusted.

If you are getting untrusted connection errors, we should help you figure out why so that problem can be solved. Could you check the error page for a code in parentheses (separated_by_underscore_characters). It might be in a Technical Details section of the page. Please paste that back here.

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.


A unique issue affecting many Windows 10 upgraders is that they inadvertently enabled parental control on their own browsing, which causes seemingly random blockages.
