Google appears to have its own agenda with respect to which browsers it makes add-ons for... Have you checked out any other speech-to-text add-ons? this one came up in a search: [https://addons.mozilla.org/en-US/firefox/addon/text-to-voice/ Text to Voice :: Add-ons for Firefox] (I haven't tried it myself). ---- I think you probably can go back to Firefox 3.6.28 if you like. However, it will only get security updates for another month or so. Please make a backup of your settings first in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.) You can get the latest Firefox 3.6 installer here: http://www.mozilla.com/firefox/all-older

Text to voice is just as it says, not voice to text.

Oh sorry, I read that wrong, didn't I. ---- Have you tried the speech-to-text built in to Windows Vista? Probably not as convenient as having it right in the browser.
