[Trisquel-users] Re : Why is Ubuntu Web Browser in the repository?

[lcerf]

The first time Abrowser is launched (after every update, I believe), the  
displayed page proposes, among privacy settings, to disable JavaScript or to  
enable LibreJS, whose icon informs the user whenever proprietary JavaScript  
is blocked and allows to "add/remove pages's domain to/from whitelist" (and  
"to complain to site owner" too!).  Neither option is enabled by default.   
The LibreJS one could.  It warns about proprietary JavaScript and gives  
control, as you want.
