You could do this with a browser extension, such as [https://addons.mozilla.org/firefox/addon/add-custom-search-engine/ Add Custom Search Engine]. Just use <code>https://www.google<!---->.com.ua/search?q=%s</code> as the search URL and <code>https://www.google<!---->.com.ua/favicon.ico</code> as the favicon URL. Hope this helps. <blockquote>'''NOTE:''' In most cases (like with Add Custom Search Engine), once you have created the search engine and added it to Firefox, you can uninstall the browser extension.</blockquote>

Thanks!
