The workaround is using Firefox's private window.
I removed my saved login and dumped my data, cookies, site data, and cache but that didn't help. That has been a pain restoring other sites I had saved, but that's another story.

</p><p>Some possible issues to consider:
</p><p>(A) If you are using a VPN when accessing these sites, try without the VPN.
</p><p>When you are using a VPN, your IP address is from a remote system used by many strangers. So if that IP address is temporarily banned due to someone else's activity, that also will affect you. If you need the VPN, try selecting a different server or exit node in your VPN software.
</p><p>(B) If you have customized any privacy preferences that affect browser requests -- for example, modifying your "user agent" or referring site header -- you may need to undo those changes
</p><p>Also, some add-ons may modify headers in a way that looks suspicious to these systems. We can't really tell how your browser identified itself to the problem site based on how it identified itself to <em>this</em> site, because add-ons are restricted in how they interact with this site. Can you think of any add-ons you use that might make privacy-related tweaks to your requests?
</p><p>(C) If you have Firefox set not to accept ANY cookies, that also could be a problem for some sites
</p><p>(D) Maybe your requests are modified by an intermediary (such as a proxy server, your security software, or an interloper)
</p><p>Although most people are not intentionally using a proxy server, Firefox may discover one set up in your system settings. Sometimes forcing Firefox to ignore those settings helps with weird connection issues. Here's how:
</p><p>Open the Settings page using either:
</p>
<ul><li> "3-bar" menu button &gt; Settings
</li><li> (menu bar) Tools &gt; Settings
</li><li> type or paste <strong>about:preferences</strong> into the address bar and press Enter/Return to load it
</li></ul>
<p>In the very tiny search box at the top of the page, type <em>proxy</em> and Firefox should filter to the "Network Settings" section of the page.
</p><p>Click the Settings button, change the top setting to "No Proxy" and then click the OK button at the bottom of the dialog to save your change.
</p><p>Any difference?
</p>Okay.

Many others just don't give me access to the site, no error message, just can't log in. When I then switch to Edge and do the same thing it works. To me that means it is the browser not the site. Basically I have switched to Edge because I can get access to everything I could prior to loading Norton. Looking at the Firefox blog there are thousands of others with the same issue but no solutions posted

After visiting a working part of the site and successfully searching for a flight, I tried your url again and the site redirects me to the oops page. Looks a site hiccup to me.
