I have several "how to" documents at work that I've created to help make remembering the details of certain tasks easier. For several of these, I've got a mailto: link to some contact person which also has a subject line pre-filled with our account number so that I (or whoever uses the document) doesn't have to copy/paste all that stuff. So the link is in a WORD DOC not in a web page. I keep two browsers open at work: Chrome, which is logged into my personal Gmail account, and Firefox, which is logged into my work email (which uses Gmail). It is critical that when I sent a work email (say, by clicking the mailto: link in the Word doc file) that it opens in FIREFOX so that it's coming from my work account. What currently happens is that I right click the link and click "Open Hyperlink" and it launches a CHROME window, loads Gmail, and prefills the to: and subject: fields. *sigh* I've set Firefox as my default browser through its settings. I also shut down Firefox entirely and followed the directions [http://kb.mozillazine.org/Setting_Your_Default_Browser#Force_Firefox_to_make_itself_the_default here] which say: ''If Firefox already thinks that it is default, exit Firefox completely, go to "Start Menu -> Run" and enter this into the text box: '''firefox.exe -silent -setDefaultBrowser''''' I've done both of those things, and it still opens the mailto: link in Chrome. Could someone please help me?
