The Firefox start page comes up fine but when I try to go to another website I get a massage that the site is not secure. This applies to all sites. I have Google available and I can go there to view all these sites but Firefox has all my bookmarks, etc and is much handier-- if it works. I've re-booted the computer as well as the 4G hotspot so this isn't the problem.

Firefox updates overnight and I can't access any of the normal websites (Facebook, google, Yahoo, youtube, etc.). I get the "security error" message but don't get the "exception" option to bypass and enable access to the mentioned websites. I am able to access some non usual forums (where I get the exception option). What can I do to solve this?

Looked through other support articles about this issue, tried the solutions: clearing the web cache and cookies, and disable Avast web scanning. I have no other antivirus software. I am having to use Chrome to ask this question because this support site is not loading properly in Firefox.

Just switched to Firefox from Chrome, I'm about to switch back.

Firefox just did an automatic update to version 65.0 (Firefox Quantum, 32 bit) and ALL of my websites are blocked with the message, "Your connection is not secure".

This is what I get back when I try to access Google: "The owner of www.google.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website."

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.


Even your own website is stopped with this message: "The owner of qsurvey.mozilla.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website."

...and Firefox will NOT allow me to bypass this warning, making the browser useless. I'm using Chrome to send you this message.

Since ver 65.0 auto downloaded, Firefox shows "Connection Not Secure" to patently obvious safe webpages eg: .org.uk; bbc.co.uk; Mozilla ! Most will not download at all. Some show text like files all aligned left. All these webpages connected normally prior to the update. How do I revert to version 64? PS I clicked the troubleshooting Info "Auto Add" button below on my previous attempt but the entire details completely wiped. I now see in my Inbox a "notifications@support.mozilla.org" message to complete joining but clicking that just brings up a webpage of left aligned text. So please respond by email

Yesterday I upgraded to the newest version of Firefox (66.0, 64-bit). I use Avast Antivirus for virus protection, and I noticed after I upgraded to the new version of Firefox and went to go online, the Avast Online Security Browser Extension showed that the automatic blocking of trackers was disabled, so I clicked More Settings and re-checked the things that were previously unchecked (the do not track boxes), afterwhich I clicked Save, and everything was A-OK.

After I was finished, I closed the page I was on.

When I went back in awhile later, the same thing occurred, and I had to do the same thing all over again.

I'm not sure what to do so I don't have to keep repeating the same process over & over again. Any help would be greatly appreciated, as I'm unsure whether this is Firefox-related or Avast-related. I did post over at Avast's forums, too.

Thanks in advance.
