User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312 Build Identifier: It should be possible to spell-check any form field, in HTML and XUL applications. Although one can expect the OS to provide these services, I believe that there is a higher chance to get it implemented for the Mozilla framework. (Now I need to copy this text to Word and spell-check it...) Reproducible: Always Steps to Reproduce:

Every web application needs a spellchecker. Every web developer had to deal with this problem. Companies have already spent hundreds of millions on custom spellcheckers for web applications. If the Mozilla framework supported this feature, I believe that it will help people to choose it as their web application platform (again copy to word and check…)
