If I go to someone's user profile page and click on 'accounts' to see their associated accounts, and click on a profile link to another SOFU site, this opens a new browser page/tab. It would be much more polite if this was not done -- please let me decide if I wish to open a link in a new tab or not, thanks.

This is coming from the `target="_blank"` attribute in the anchor tag, in the <https://stackoverflow.com/users/flair/<userid>.html> iframe.
