It works well for eliminating the idiotic decision Ebay made to open a new tab for Every. Single. Click. on search results.

I'd like it better if it also prevented new tabs on things other than search results. For example, clicking on anything under "People who viewed this item also viewed" list, or just browsing in the categories instead of searching still opens new tabs.

It appears eBay made a change that makes all your clicks open in a new tab. This fixes it. Thanks!
