Android Browser -Can it be set to NOT open new tabs?

I have an elderly friend that has an app - the app has a button that opens a website. When this person taps that button multiple times during the day a new browser tab opens every time. I can't teach this person how to close tabs, they just don't get it and at the end of a week that have 30 tabs open. Naturally the tablet slows to a crawl.... Is there a setting that prevents new tabs from being opened? Instead just using only one tab for everything? Thanks for the help....
