NoScript filters that link as a potential XSS attack. I guess it doesn't like brackets in URLs. That could be a problem for Wolfram if the noscript author can't find a safe way to whitelist wolfram alpha links.
on a limb: I would say the overlap of no-script to wolframalpha users is minimal / WolframAlpha has other bigger problems to fix first.
How is that noscript strips URLs with brackets is WolframAlpha's problem?
my point exactly / sorry for confusion.
Mathematica (and thus Wolfram Alpha) is unusual in it's use of brackets to enclose function arguments. Every other computer algebra system I've used has been content with parentheses. And NoScript is pretty much the leading edge for browser security, so if it thinks brackets are dangerous, they probably are and other browsers could follow at any time. Wolfram Alpha's direct use of Mathematica's notation in URLs seems a bit naive, and it wouldn't be the first time Wolfram embarrassingly misunderstood the way the web works.
how would brackets be dangerous? just because the author of noscript thinks they are, doesn't make them so. he's definitely not infallible.
