The "share" function in the tab is a security risk. It exposes email. I don't know who any of these people are. Do they have my email too? Why do I have theirs? Yet again, FF incorporated a "feature" that's unwanted.
It looks like a blatant cash-grab and advertising for other platforms such as Twitter, LinkdIn, etc. I don't want this. The only purpose a browser has is to display a web page.
A function to remove "Share" from tabs is required.
