Over the past 2 months, there are a few websites I can not log onto with my Firefox browser (current version 106xx); I don't have this problem with other browsers. I recently tried to download and install an older version of Firefox. But after losing all my passwords and other data when I uninstalled the current version, the older reinstalled version auto-updated BEFORE I could use it. I tried logging with my other computer that had an older version of Firefox (which worked fine on this website the last time I used it ---ver102xx), but it again auto-updated before I was able to log on. I was told by the site's IT team that it could be your new "cross tracking prevention"; I disabled it and emptied the cache for this site, but still get the attached message when I try to log on. HELP please. David S
