In Firefox 3.5 and before, this function would automatically case-fold any queries so that a search for "foo" would match "Foo" or "foo". In Firefox 3.6 and later this function is now case-sensitive so that a query for "foo" will only match "foo" and not "Foo". For more background on this, please see the comment from Henri Sivonen about the change. You can also look at the relevant part of the standard, which states which parts of the API are case-sensitive and which parts aren't.Firefox: Before Firefox 19, this method was returning a NodeList; it was then changed to reflects the spec change.Firefox for Android: Before Firefox 19, this method was returning a NodeList; it was then changed to reflects the spec change.Quest Browser: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Opera: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Opera Android: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Safari: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Safari on iOS: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.Samsung Internet: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.WebView Android: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.WebView on iOS: Initially, this method was returning a NodeList; it was then changed to reflect the spec change.
