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.

Chrome: Earlier versions of Chrome incorrectly return true when a tab is first opened, but it starts reporting the correct connectivity status after the first network event. Windows: 11, macOS: 14, ChromeOS: 13, Linux: Always returns true. For history, see bug 40530968.Firefox: Since Firefox 4 the browser returns true when 'Work Offline' mode is disabled and false when it is enabled, regardless of actual connectivity. Since Firefox 41, on OS X and Windows, the returned values follow the actual network connectivity, unless 'Work offline' mode is selected (where it will always return false).Internet Explorer: in Internet Explorer 8 'online' and 'offline' events are raised on the document.body; under IE 9 they are raised on both document.body and window.Opera: From Opera 11.1 until Opera 12.1, the browser returns true when 'Work Offline' mode is disabled and false when it is enabled, regardless of actual connectivity.Opera Android: From Opera 11.1 until Opera 12.1, the browser returns true when 'Work Offline' mode is disabled and false when it is enabled, regardless of actual connectivity.WebView Android: Can incorrectly return true, see bug 41369933.
