Firefox integration?

[cemeyer]

Would it be easy to adapt this to work in Firefox? I use webmail clients (Gmail, Outlook Web Access) that receive emails from Outlook with these smilies in it. An example from 'view source':

<font face="Wingdings" color="#1F497D" size="2"><span style="font-size:11pt;">J</span></font>

Gmail is a no-go - keeping up with the changes to the DOM is impossible as Google obfuscates it deliberately to prevent this sort of plug-in. I guess Outlook's the same, though there is a chance it might be more stable and therefore doable.

Maybe try out the alternate solution here? https://superuser.com/a/1029797
