Description (last modified by arma)

When I go to certain sites in the Tor Browser 8.0, I get a new window popping up, which is the same size as my current browser window, which looks like it comes from noscript. It says "NoScript XSS Warning" at the top, and the window title is moz-extension://4536b558-.... NoScript XSS Warning", and there's a bit of text towards the top that says

NoScript detected a potential Cross-Site Scripting attack

from to

Suspicious data:

(URL);src=8397396;type=espng0;cat=espna0;u1=;u2=[s.products];u3=[c.promocode];u4=[payment method];u5=[c.SWID];u6=[c.UNID];u7=[c.NavMethod];u8=[Trial/Monthly/Annual];dc_lat=;dc_rdid=;tag_for_child_directed_treatment=;tfua=;npa=;ord=9016327828417.457?

and towards the bottom I have the options to block, always block, allow, always allow, and then an ok button.

The example url in this case was

(I've noticed the behavior happens pretty consistently with espn urls.)

I'm not sure quite what behavior I would expect instead, but "making a new huge window that's mostly whitespace and that prevents me from doing anything on any tab until I've made the window go away" was not it. :)

I agree, as is, it's pretty inconvenient. Also I had one of those existential thoughts "Will these settings persists?" after I kept getting that warning and had to chose to the "Always block from ..." option, not good!

This just happened to me on Tor Browser 8.0, so I am updating the title / description to indicate that it's not just an alpha thing.

Giorgio: Is there a way to make this XSS warning less obtrusive? We have users that are scare as hell by those popups thinking they got a virus or something. I guess a lot of them are very likely false positives, too (like the one on the nytimes website)?
