Tabs in Safari keep going back to the previous tab when I press on a link or open something within a tab.

Randomly, my MacBook Pro undoes an action I do whenever I open an email or press on a link it sort of refreshes the screen and stays on the previous page. This happens somewhat frequently and its been bothering me as sometimes I need to press on the link again after it clearly shows that its opening the link I pressed on. This also isn't a network problem as I've tried this in different places with different WiFi connections. I appreciate any help and thank you for your time!

Did you try making changes to your Safari Preferences...?
