Firefox Redirect Issue domain.com/wp-signup.php?new=domain.com

I have a redirect issue with my multisite. I thought it was resolved and it is in every browser except firefox. My site is my web design site with template sites built in. Initially i got the domain.com/wp-signup.php?new=domain.com when visiting my site with out the www. I was able to find the below code and put it in my htaccess

# Redirect non-www urls to www
RewriteEngine on
RewriteCond %{HTTP_HOST} ^domain\.com [NC]
RewriteRule (.*) https://www.domain.com/$1 [R=301,L]

That seems to have solved the issue in every browser(Chrome, IE, Android) However in firefox i still have the issue. I cleared out the cache and the history and even reinstalled firefox but it still happens and has “Registration has been disabled.” instead of parts of my site.
My domain is bdbwebdesign.com none of these issues happen when you use https://www.bdbwebdesign.com only the non www. version. I tried adding define( ‘NOBLOGREDIRECT’, ‘https://yourdomain.com/’ ); to my wp-config but that just caused a redirect error. I tried both with and without the aformentioned code in my htaccess.
