Most ads are now Javascript-based, and altering the code is against their policy... so I doubt I can do much about it without violating contracts. I prefer external links openinig in new windows as well...
Some browsers can set in on the client side I suppose... But generally it is a server side html link tag setting:
<a href=.....> vs. <a target="_blank" href=.....>
Disclaimer: Please use caution when opening messages, my grasp on reality may have shaken loose during transmission (going on rusty memory circuits), even though my tin foil hat is regularly audited for potential supply chain tampering. I also eat whatever crayons are put in front of me.
