Internet Explorer 9 is big improvement over Internet Explorer 8 but it is still the only modern browser that does not include spell check as a native feature. With this release Microsoft focused more on the browser engine adding HTML 5 support and hardware acceleration. Web standards and performance are very important but the lack of a basic feature such as spell check can prevent users from making Internet Explorer 9 their default browser.

Thankfully, there are a number of free spell check add-ons available for Internet Explorer 9 that will help you modernize your browser:

    - The first option has been the unofficial Internet Explorer spell check add-on for years known as IE Spell. This free add-on allows you to check the spelling of any text box by right clicking and selecting Check Spelling.

    - My new favorite spell check add-on for Internet Explorer 9 is called Speckie. This free add-on adds the familiar red squiggly line under misspelled words similar to other browsers or Microsoft Word.
