Most of the time when I have a programming problem, I would like to search only on Stack Overflow, or Stack Exchange sites. So, I need to bookmark Stack Exchange sites, go there and type in my search query. 

I would like to skip all these steps and enter my search terms directly in my browser's search bar. Is this possible (maybe with a plugin)? If not, could this feature be added?

Answer: 
We already insert OpenSearch metadata in every page. Since your screenshot looks like Firefox, and Firefox supports OpenSearch by default, all you have to do is go to <http://stackoverflow.com>, and then open the very popup that's in your screenshot – it will display the option *Add "Stack Overflow"*.
The query string for **Stack Overflow** is <https://stackoverflow.com/search?q=%s>

**How to set it:**

1. Open Google Chrome
2. Go to chrome://settings/searchEngines
3. On "Site search" section click "Add" button
4. Fill the form like on the picture with URL=https://stackoverflow.com/search?q=%s and click "Add"
5. Use "so something" in Address bar to search for "something" on Stack Overflow
