How do I remove the 20-30 browsing history tabs constantly showing up on the top of the screen?

@leocg I'm not interested in removing the menu tab up in the upper left corner. I just have no use for my browsing history showing up across the top of the page. I never use it but I can see where others could find it useful. If there was a easy way to remove that, I'd do it but it is no big deal. I've tried many other browsers but Opera is still my main go to path. Thank you for your reply.

Could someone please guide me to the place where I can remove the tabs of browsing history from coming across the top of the page to the right of the Menu tab?
