I've been getting security warnings from my security software "Bitdefender" for firefox. Bitdefender is giving me warnings about "suspicious connection blocked" for "gitcdn.link" within Firefox as an "Online threat prevention". Word for word is as follows "Suspicious connection blocked. Feature: Online Threat Prevention. firefox.exe attempted to establish a connection relying on an unmatching security certificate to gitcdn.link. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one." First: I did not access "github" which "gitcdn.link" appears to be linked to in accordance to a general google search. Second: This warning appears every time that I begin using firefox as well as periodically while I am using firefox. Third: in my process of trying to report this problem mozilla.com directed to a "support" website that would not take my mozilla firefox log in while it had a box stating to "sign in with github". I'd like to know if mozilla uses the "gitcdn.link" in it's firefox browser in some way? And if so, I would like firefox to corroborate with bitdefender to resolve the security issue. If not, then I would like a way to get/have a clean firefox browser that doesn't continuously get seecurity warnings relating to firefox and it's operation. Please help

I forgot to add that this has been occurring and happens multiple times a day ever since I updated firefox by going to the Mozilla website and downloading and installing the 64 bit firefox broser from mozilla.com on March 14th, 2021.
