[Help-librejs] LibreJS prevent me to use Mastodon and GNU Social

[Davide Lombardo]

I have installed LibreJS in my browser, but it prevent me from using 
Mastodon.org.uk and even the FSF GNU Social page. I suppose they should 
be Free Software friendly websites. Does Mastodon and GNU Social use 
proprietary JavaScript ? Or is it my LibreJS plugin wrong ?
