Again the problem: any site from Mozilla, including Thunderbird, Firefox, Firefox Addons pages show as plain text with no styling. And only mozilla sites. Every other page loads just fine. This also has (probably??) disabled and uninstalled all my addons. In addition, sync isn't working. But again, every other site loads fine.

This problem isn't happening in MS edge or chrome.

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

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


-

Here's what I have done so far:

Restart Firefox

Clear cache and settings

Restart Computer

Restart Firefox without addons

Uninstall/Reinstall Firefox

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

I checked my firewall, antivirus, tried using a VPN (trying everything at this point), updated all other software like java

This happened after a recent update to version 40.0.3. Using Windows 10

Any ideas?

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

  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.

No, this is not a good solution. It's not the problem in Avast or another security tool, it's the problem in Firefox. You can't ask Firefox users to disable security options so Firefox can work. It's not the solution. Fix Firefox! SSL scanning works in Opera browser, in IE browser, in every other browser but doesn't work in Firefox so => The problem is in Firefox!!!
