create a setting to either enable or disable opening links in new window or tab
links in messages used to open in a new tab or window. now they are suddenly opening in the same tab or window. Some might like this, others, like me, not. So give us an option. Also consider this for settings in Calendar, settings, news, and other yahoo features.
In New Mail, links in emails still open in new tabs/windows. If you still find that the issue is happening, please see this help page for troubleshooting:

Yes. This is extremely frustrating and silly of yahoo mail. Why not open in new tab like they used to when a link in an email is clicked. Do you want us to also move out of Yahoo Mail?
