All was fine with Tor Browser 7.0.2, I can see comments via Facebook on https://fr.sputniknews.com under all news. But it seems there's a bug now. Do you have a solution ? If not, is it risky to still run Tor Browser 7.0.2 ? Please avoid "Do not read Sputniknews anymore" comment ;-)
It seems to be a NoScript bug. When I disable 'Sanitize cross-site suspicious requests' in
NoScript Options\Advanced\XSS then Facebook comments come back. So, it is the first solution to disable 'Sanitize...', but we are vulnerable to XSS attack if permanently disabled.
Second solution: tweak the NoScript
Options|Advanced|XSS|Anti-XSS Protection Exceptions rules but I can not write such rule... not geek enough ;-). And last solution : post a bug report at NoScript forum. What I am going to do.
