Is this a Good/Strong Security Moz-FF Add-on?

I'm not exactly sure whether to (Option 1) "Save" in this program, or "Add to Whitelist" (Option 2) in the GREEN HIGHLIGHT - attached in screenshot, below.

I've been alternating between both choices, mostly just building a Whitelist), and I realize that http"S" pages may not have all the functionality of standard http, but is there much difference between deciding on either option 1 or option 2, please?

Thanks in advance,
glenn...

 

Not sure what ye are asking, except that https is a secure connection to the page in question. Though, I always check the sites certificates to make sure they are up to date.

 

Thanks...I suppose the simplest way to ask it is that I was hoping to get a breakdwn (explanation) between the two options I've been choosing from upon the prompt from this add-on ("HTTPS EVERYWHERE"), please.

I understand what a "Whitelist" is, so I'm wondering if I "Save" instead, am I potentially setting myself for any sort of problems by doing that ("Saving the rule..." as they put it), rather than just building the whitelist, please?

I'm trying to better (more fully) understand this add-on ("HTTPS Everywhere").
