FIREFOX even in safe mode failing to allow login to Spectrum.net. EDGE and OPERA do allow, problem began approximately 3-14-2021. The login process ends up with a message "We're sorry, something has gone wrong. Please try again." LASTPASS is NOT the cause. Thanks Fred, but none of the suggestions helped, and most of them did not apply. The site does load, but the verification process acts differently now than it previously did (and still does with the other browsers). There are now several "redirecting to" messages displayed that did not happen prior to this. Also, in FIREFOX I used the username/password reset option, after/during which the login succeeded. NOTE that the problem is a LOGIN problem and not a connection problem. Nothing else in my computer has changed; same security software running as it was before Firefox started this failure. I don't think any updates to any of those happened at the time of failure. There was a major WIN-10 update, and I did experience some problems as a result, and I do not recall if Firefox started to fail at that time. I don't think the update was connected, but not sure. Everything else still works normal (and well) in Firefox.
