From the stats: “computer without mouth” and “firefox without mouth.” You don’t need your mouth to use a computer or a browser unless you use the following:
A bite or sip/puff switch or other breath control
A Jouse, Lipsync, QuadJoy or similar device
If you want to use the computer without a mouse, you can do that too. For instance:
Mouse Keys
Mouse Grid
Various switches and switch interfaces, such as Stealth or PI Engineering
Accessibility.typeaheadfind and typeaheadfind.linksonly, or the apostrophe
Hand to Mouth: Assistive Technology 
Is there a users forum for Dragon Naturally? It used to be at KnowBrainer, but am unable to log into it there anymore.
Thanks,

Sorry for the late reply. I tried logging in myself, and the page just kept spinning. It’s apparently down temporarily. I’ve had better luck with Speech Computing, anyway.
