As far as I recall you simply install it from your online account, or add the feature via SecurityCenter > Navigation > Features if available there.
It then adds for all compaible browsers.
Perhaps Technical Support can help, it's free: Technical Support/Customer Service

Please try the following:
- Open another browser than Firefox
- Download https://downloads.truekey.com/firefox... to your desktop
- Open Firefox and visit about:addons
- Drag the xpi file inside Firefox and say yes to the installation prompts
Let me know if it works after that.
Thank you! It worked!
