Club member access in Firefox browser

I apologize for not making my prior request topic clear.  I am a club member in several clubs using FreeToastHost for the club website. I agreed to my information being stored and used in the club's website. My Firefox browser isn't letting me login as a member.  My name doesn't display in the Club Member Login popup box when using Firefox browser.  My names does display when using Edge browser.  Do you know how this issue with Firefox be fixed?  or What I have to do to fix this issue. I spoke with one of my club's site administrator regarding this issue.  They didn't know how to fix it.  Just an FYI, I am a site administrator for one of my clubs using FreeToastHost.  On Firefox, I can login as site adminstrator.  

Is your name the same on all sites?  Have you tried using your email address instead of your name?  

Which club are you referring to?
