OEM Win11 Pro, Firefox 99.0.1, BD Total Security. Edge and Explorer "can use", Firefox (and Chrome) "isn't installed on your device".
BD was the second app installed, after Firefox from MS Store.

There is no option TO install the anti-tracker extension.
Here is screenshot...
As much as I hated to on a new system, I did uninstall, reinstall Firefox. Instead of the MS Store, I downloaded direct from Mozilla, (using Edge) and problem solved. I was able to install the anti-tracker from the privacy window in BD.
Thanks for reading.
