For about a week now, every time I log in to Yahoo Mail from Chrome an overlay appears asking me to install an extension, in order to get the full Yahoo experience in Chrome. How do I get rid of it permanently? Without installing the extension, obviously.
How to permanently get rid of the Yahoo Extension overlay
yahoo mail;google chrome extensions
Kilrplatypus' solution is almost perfect. However, it has the sub-subdomain names in the rules (us-mg5) which is not constant.The more general filter rules are:mail.yahoo.com###uh-dmos-msgbox  mail.yahoo.com##.uh-dmos-msgbox  mail.yahoo.com###uh-dmos-overlay  mail.yahoo.com##.uh-dmos-overlay  mail.yahoo.com###uh-dmos-wrapperBTW, I just used it on a client's computer and took care of this annoying popup very nicely.
