Created attachment 671047 [details] spell checker errors on Gmail.jpg User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0 Build ID: 20121010144125 Steps to reproduce: Typing email messages in Gmail Actual results: The latter few letters of numerous words are underlined indicating wrong spelling when the full words are spelled correctly. Expected results: The red squiggly line indicating a misspelling should not be showing up under partial parts of words. This only started happening after I installed the latest version of Firefox 16.0.1. Prior to this, I had never had this issue with Gmail.
