Same person. But I can on my iphone using Firefox. And I can login using Safari on desktop.

Did you try with Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

Try putting the login information into a notepad like app and then copy and paste into the site. Make sure there are no spaces before and after the username and password. What version of Firefox?

Thanks, but we've tried on two different computers, with 2 different users on 2 different accounts. I'll Safari or Opera for at least this one bank account. I use Lastpass as my PW manager to log in and I have typed it in manually in case some screwy with Firefox. I'll try troubleshoot mode. Never thought about that.

Thanks for the help though. Steve

Thanks. I was able to fixed the problem with your suggestion. I enable and disabled add ons. The culprit, ClearURLs Version 1.27.3

I'll contact Kevin. This add on will not let me log into the BECU.org bank site.

Thanks again

Using my PC with Firefox as my browser, I am unable to log into my online banking account. If I use Chrome or Edge (or my cell phone), I log into my bank account without any issues. It's been a problem for the past month.
