Firefox not loading Mozilla's websites, including addon page, tried entirely reinstalling, dns flushing, absolutely everything; still same. Works on chromium.
Just as the title says. I tried it all, completely removing it, including the profiles, tried disabling everything that has to do with internet traffic (ESET, ZA and MB), tried restarting and flushing DNS cache. It started today by loading pages extremely slowly, now I can even get the extensions I need, primarily NoScript, since I can't even load these sites properly, only the HTML seems to load.
For instance: https://marketplace.firefox.com/ shows only ×, https://addons.mozilla.org/en-US/firefox/ only loads the HTML, no CSS, nothing. All other websites work fine, with the exception of slowness and painful webm errors which were occurring since yesterday.

There is security software like Avast and Kaspersky and BitDefender and ESET that intercept secure connections and send their own certificate.
Are you using anything like these?
You may have corrupt cert8.db file. cert8.db stores all your security certificate settings.
Type about:support in the address bar and press enter.
Under the page logo on the left side you will see Application Basics. Under this find Profile Folder. To it’s right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.
Locate the cert8.dbfile. Then rename or delete it. Restart Firefox.

hi, do you get a particular error message when you try loading https://addons.cdn.mozilla.net/static/img/app-icons/med/firefox.png ?
Seems like the firefox doesn't recognize the certificate; addons.cdn.mozilla.net uses an invalid security certificate.
does it make a difference if you try disabling https scanning in eset like described at http://support.eset.com/kb3126/ ...

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.
philipp and FredMcD: The issue seemed to be with ESET's scanner, what's weird is that disabling ESET did not do anything, however disabling this particular function did. Now I am not entirely sure about the issue, I did what Fred said, despite the fact that I did uninstall firefox entirely 3 times, including the profiles and whatnot and it did not work - now it did. I then enabled the SSL scanning once again and everything works, so no idea what the actual problem was, apparently the cert8, but the multiple clean uninstalls would disapprove that, right?
Firefox comes in two or more folders on all computers. They are;
Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And one folder in the profile of each user on the computer.
If you remove the Firefox folder, the user folders would not be affected. The security certificate file is in your profile folder.
