I keep getting '500 error' when trying to login to my Evergy account. The Evergy support was helpful so I could use Google Chrome however I would like to use my Firefox browser. They had me clear browser history, cookies and other site data and cached images and files. Then restart the Google Chrome browser. How can I get the same data cleared in Firefox?

I have used the privacy and security settings in Firefox and cleared cache and history and cookies, but still can't log into my account.

This has been an issue since 12/01/2024

Recently when I try to access any of my accounts on my Mobile Phone through Firefox I get an error that says This Website Requires A Secure Connection. I don't get this message from any other browser on my Mobile Phone and I don't get this message on my Desktop. It tells me to try again or go to the Advance Tab and it still does not go to a site.

The bookmarks and everything works except to take me to a website.

I did see the question here: https://support.mozilla.org/en-US/questions/1448269

And the answer is not useful, mainly because apt-get does not use a browser to update its cache.

Err:16 https://packages.mozilla.org/apt mozilla/main all Packages

 400  Bad Request [IP: 34.160.78.70]

E: Failed to fetch https://packages.mozilla.org/apt/dists/mozilla/main/binary-all/Packages 400 Bad Request [IP: 34.160.78.70 443] E: Some index files failed to download. They have been ignored, or old ones used instead.

Using curl/wget/httpie works as intended, just apt-get update fails.

Any help would be appreciated.
