[Trisquel-users] GNU LibreJs on Tor Browser

[forna]

Hi all,

I would like to add LibreJs to Tor Browser. I tried to install the .xpi file  
from http://www.gnu.org/s/librejs/distribution/librejs-6.0.1.xpi but it  
appears that it's not compatible with the browser.
So my questions are:
- Is there a way to install LibreJs on Tor Browser?
- If yes, is it safe to do so?
Greetings
