Buy it and run it separately I do not see any options for a Extension.. https://www.trackoff.com/en

Is there a reason running version 49 as it is a security risk. You could be running 52.4.1 ESR that gets updates. https://www.mozilla.org/en-US/firefox/organizations/all/

Please let us know if this solved your issue or if need further assistance.

Hello from TrackOFF!

We've updated our Firefox extension in our newer releases. If you are seeing your Firefox extension label "Legacy", download our latest installer here: https://trackoff.com/downloads/blue/TrackOFF.exe

Remove your current Firefox extension and it will be replaced when enable Firefox in the "Browsers" tab in TrackOFF.
