Trisquel Mini (Trisquel 11) Installing Tor Browser

I've noticed that the installer (Add/Remove Applications) doesn't allow you to select the tor browser option when clicking on it. It will look like it is trying to complete the process but just never selects it. I've seen comments that Tor Browser might not be 100% free software (but mostly OSS) and that might be why that option isn't working. Also I think that if I want to install it via command line I'd have to add the right repository like regular Ubuntu. Anyway the torbrowser did work well enough by just manually downloading the package/archive, extracting it and executing it.
