Hello,

Thank you for reaching out to us regarding the issue you are experiencing with Firefox. I understand that you are having trouble accessing certain websites that are marked as 'Not Secure' by Firefox.

Firefox has implemented enhanced security measures to protect users from potentially unsafe websites. When a website is marked as 'Not Secure' and uses HTTP instead of HTTPS, it means that the connection between your browser and the website is not encrypted, which can potentially expose your data to security risks.

While Firefox prioritizes user security, we also understand that there may be certain websites you trust and want to access despite the lack of HTTPS. To proceed to such websites, you can click on the 'Advanced' or 'Proceed' option (depending on the specific warning message) to bypass the security warning and access the site. However, please be cautious when doing this and ensure that you trust the website you are visiting.

It's worth noting that some websites may have legitimate reasons for not using HTTPS, but it's generally recommended to avoid entering sensitive information on such sites.

If you encounter any specific websites that you believe should be marked as secure, you can provide feedback to Mozilla through the 'Report Deceptive Site' feature in Firefox. This will help us continuously improve our security measures.

If you have any further questions or need assistance with any other Firefox-related issues, feel free to ask. We are here to help.

Best regards, Firefox Support Volunteer

I have several bookmarked sites that I know are secure, yet because the http address is odd? firefox won't load the pages, where as Internet exploder will access them.

Hi Steve, what's the exact error message? Sometimes you need to click an Advanced button to get the full story, and the ALL_CAPS error code. (Article on those codes: How to troubleshoot security error codes on secure websites).

Sometimes websites update their addresses and old bookmarks become a dead end. You could try updating the bookmarks once you find working pages on the site (either by starting from the home page or by visiting from a search engine result).

I'm seeing that it's most sites that I use to have no issues with. The Android version is a crap show on many levels. I'm moving to Edge only because "It Works".

If you would like to keep using Firefox, please participate in troubleshooting. The first step is to share the specific error message and error code. See the earlier replies in this thread.
