I do not understand a question "Were you intending to visit the site ?" Which site are you talking about ? And how does that relate to my problem ??
Did you actually make the connection to the site, or did it happen without your intention ?
The site that you get notified about in the Alerts.
Finding why the alerts are occurring could lead to the solution. And the reason for the questions and actions to try and pinpoint why it is happening.
David, I will follow your advice. And no, I have not added or updated any add-ons for couple years now...
Add-ons could well be updating without your knowledge.
If you have more than one browser, is this happening on that also ?
