When browsing new window open instead of reusing the one thats open

Help needed.

When browsing on Ebay i have noticed lately that when i click on an item i want to look at it opens a new browser window which gets quite annoying when im only used to seeing 1 window that opens new item on the same page. How can i turn it off to stop loading more pages every time.

Not very sure why that happens, but you can right click and “open a new tab” or press on the scroll part on the mouse to do the same thing.
