TBA: Is the "Slow Script" warning is triggered too often?
When loading Google News, the Slow Script warning is triggered every time the page is loaded. Is this because the timeout is too low and loading the page over Tor exceeds the threshold every time? Is there something else we can do for tuning this for a better user experience?
We can start by looking at nsGlobalWindowInner::SlowScriptResponse() in dom/base/nsGlobalWindowInner.cpp and see when it's called and why.
