gmail app takes over browser based yahoo email composition?

[AC Question]

I have been using the yahoo, browser based (not chrome), mobile mail (not the yahoo mail android app), for sending and receiving emails on my android phone for quite a while without any problems. All of the sudden when i go to the yahoo mail web page and begin to compose an email, I open my yahoo contact list and choose one of them to insert into the email, but instead of inserting into the yahoo email I am trying to compose, the gmail app on my phone opens and the contact i wanted to insert into the yahoo email inserts into a gmail email that is ready for composition. I would like to straighten this out but don't know what to do about it.
Anybody got any help on this?

Welcome to Android Central! Try going to Settings>Apps>All (or, if you have a Samsung device, the App Manager), select Gmail, and tap Clear Defaults. Now try again.
