Hi,
I just installed waterfox right now to have IAT, but after installing it and restarting waterfox, I can set preferences, but I don't have any button, nor editor after right click on a textarea -> use default extension (or anything else).
On stackoverflow, I have this in the source, but on some other sites, I don't have the string itsalltext in the sources.
<img src="chrome://itsalltext/locale/gumdrop.png" title="It's All Text!" style="cursor: pointer !important; display: none !important; position: absolute !important; padding: 0px !important; margin: 0px !important; border: medium none !important; width: 28px !important; height: 14px !important; opacity: 0.0152174 !important; left: 632px !important; top: 255px !important;">
