Select and Search od Burak Unver

This Browser extension enhances web browsing by adding an instant search feature.
When you select any text on a webpage, a small "Search on Google" button appears just above the selection.
Clicking the button opens a new tab and searches the selected text using Google.
It’s a simple yet powerful tool to quickly look up information without copying and pasting text manually.

Note: You can also change default search engine.
