When tapping the three vertical dots in Android Chrome, you get the screenshot which has been attached. Under share, it shows the gmail icon. At the bottom, it shows the Google icon with a following check mark.

1. How do I turn-off "share"?
2. How can "follow" be disabled?

I did not see any obvious solution under Chrome's settings. Just to see what would happen, I deleted all history and cache, but that didn't work.

The attached screen image, also depends on the active tab. So if I am website "A", it shows I'm following "A". When I go to website "B", it shows that I am following "B".

When I go to my Google account, I don't see an option that would turn-off "share" or to disable "follow".

Since posting, I ran across this webpage: How to Use the Share Menu

these are just functions of chrome if you dont want to use them dont

Understood, but the question is: if the function was somehow "actvated"; how do you turn it off?

share just sends a email text or whatever with the current page address, its not permanant so cant be 'activated'.
dont know about following probably in the settings somewhere.

Well, as usual, the menu layout/options did not match. I did some more internet surfing, but could not find anything new.
I decided to go ahead and "nuke" the chrome and gmail settings. This has removed the gmail icon next to the share option, so the issue can be considered solved.
