Pages loading with no style of difficulty Mozilla, can not download addons

Once again the problem: any Mozilla site, like Thunderbird, Firefox, Firefox Addons pages display as plain text with no style. And only the mozilla sites. All other pages load fine. It also has (probably?) disabled and uninstalled all my addons. In addition, sync does not work. But once again, all other sites load very well.

This problem only occurs on board the MS or chrome.

When I finally sift in any page addon for the download link, I get this error:

"An error occurred during a connection to addons.cdn.mozilla.net. The peer certificate has an invalid signature. (Error code: sec_error_bad_signature) »

-

Here's what I've done so far:

Restart Firefox

Settings and clear the cache

Restart the computer

Restart Firefox without addons

Uninstall/reinstall Firefox

After above, I uninstalled and deleted all traces of Firefox with regedit and then reinstalled Firefox.

I checked my firewall, antivirus, try using a VPN (all trying at this stage), updated all the other software like java

This happened after a recent update to version 40.0.3. With the help of Windows 10

Any ideas?

Hi, in case, you're an avast user, please try to disable https scanning in avast which is known to cause various problems:

  1. Open the Avast dashboard on an affected system.
  2. Select settings in the left side menu.
  3. Adopt a Protection Active.
  4. Click on customize next to the Web Shield.
  5. Uncheck the option "Enable HTTPS analysis", and then click ok.
