Did Comcast hijack my email?

Try in webmail 

Click on the gear, then on Email Settings

In the left pane highlight Mail

In the right pane under Behavior, is "Ask for mailto link registration" checked?

If so, try unchecking it.

Are you using your gmail account at gmail.com or are you using a third party email client?  If you're going to gmail.com what browser are you using?

I am using Gmail and Chrome. But I've tested this situation with Mozilla, Edge, and Chrome. They all do it. But only on the PC. My tablet doesn't do it. Seems like the cause should be intuitively obvious, but it's not.

From the responses so far, I'm the only one experiencing this anomally?

And up to now, Xfinity is clueless as to the cause. They can't fix it because they can't define it. I have an open ticket but because it's a "repair" none of the other support agents can even see it. (?!?) So for now, it's just an annoyance. But it's also symptomatic of the "service" I've been getting from Xfinity lately. Ever since they "increased" my 1GB performance and it degraded by 500MB/S. They can't fix that either.

Hello @user_3753ba, thank you for reaching out to us on our community forums. Just to clarify, were you able to see if this article https://comca.st/3f5mr4m was able to resolve this issue?
Our team would love to take a further look at this internet speed issue you are having too. Could you please send us a private message with your full name and full address?

Bingo! Thank you. That was the solution. Finally. Will I ever know how that setting attached itself in the first place?

Things like this are endless wonders to me:

1. That even after removing and reinstalling Chrome, Firefox, Edge, and a couple of other browsers that this obscure setting can persist.

2. That after jumping through all the other hoops and over the barrels as directed by the other "support" technicians, you come out of hiding and single-handedly point to this solution. (Again, thank you!)

3. That after joining IBM in 1980 (Before there was an InterWeb or even such a thing as a PC) working various odd jobs in the technology field, ultimately retiring from LANL, I can still be shown that technology can still be shrouded in magic and mystery.

4. That after all these years, someone will come along and suggest wiping the hard drive as a solution.
