Tobii Dynavox developed a new add-on for Firefox called Tobii Dynavox Mouseless Browsing. It is based on the old add-on simply named "Mouseless Browsing". There was an issue with TD Mouseless Browsing 1.0.3 which has since been resolved. To update the TD Mouseless Browsing add-on follow these steps:
- Open Firefox
- Select the Menu button (looks like three horizontal lines typically located in the top right corner).
- Choose Add-ons
- Select the settings menu (looks like a gear or cog located to the left of the Search all add-ons field).
- Select Check for Updates
The Add-on should now be updated. No changes in Sono Key or Communicator were made.
