Firefox quick search extension idea. Is it possible?[see details]

I use search sites very often.

And in 99%开发者_高级运维 of cases search results that i need contained in first 3 links,that search engine returns.

Is it possible from programming point to write extension for Firefox,that satisfies next use case:

1. user clicks icon

2. modal window appeared

3. select search engine(e.g. Google,Yahoo or Yandex...any other)

4. write search criterion

5. click OK

6. 3 new tabs opened in browser with corresponding sites

It seems, that most complex part is to open 3 fist sites in new tabs - someth. like with using Selenium and XPATH.

Thanks for advise.

Yes, in fact, this is possible with just a Greasemonkey script. If you're using just a greasemonkey script, I'd advise making it run on google.com, then you can add a listener to the submit button, then GM_openInTab all the necessary pages.
