Spelling Suggestion in Firefox Search Toolbar

You must have seen spelling suggestions when you type anything wrong and searched in Google. (Did you mean: ***). I found something similar here while searching for any term in Google directly from Mozilla Firefox search toolbar. If you type any misspelled word, in auto suggest, it will show the corrected terms. e.g. when I started typing "plagiria", it suggested me "plagiarism" and related searches. This helps us to save our time as compared to searching the misspelled term and then getting suggestion on the result page.
