Make links open in the same tab for specific webpages.
Nowadays search engines are greedy and want to keep you on their search results page for as long as possible. That's why they make each search result open in a new tab.
With this extension, simply click the toolbar icon when you are on a search results page, and the extension will remember the domain of the page and the next time you are on that page, the extension will force links to open in the same page.
To remove the domain from the extension, simply visit the same page and click the toolbar icon again.
