Firefox: Starting in Firefox 68, the auxclick event is used to trigger the new tab on middle-click action; previously, this had been done with the click event. Apps can prevent middle-click from opening new tabs (or middle-click to paste, if that feature is enabled) by intercepting auxclick on links, and auxclick event handlers can now open popups without triggering the popup blocker.

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.

Firefox: Before Firefox 21, when an element's content does not generate a vertical scrollbar, then its scrollHeight property is equal to its clientHeight property. This can mean either the content is too short to require a scrollbar or that the element has a CSS style overflow value of visible (non-scrollable).Firefox for Android: Before Firefox for Android 21, when an element's content does not generate a vertical scrollbar, then its scrollHeight property is equal to its clientHeight property. This can mean either the content is too short to require a scrollbar or that the element has a CSS style overflow value of visible (non-scrollable).Internet Explorer: In Internet Explorer 5 through 7, if padding is set, the value of scrollHeight is equal to the sum of the top and bottom padding.

Internet Explorer: On Internet Explorer 6 through 8, the event model is different. Event listeners are attached with the non-standard EventTarget.attachEvent method. In this model, there is no equivalent to event.currentTarget and this is the global object. One solution to emulate the event.currentTarget feature is to wrap your handler in a function calling the handler using Function.prototype.call with the element as a first argument. This way, this will be the expected value.

See a live demo that triggers the bug. One workaround for the bug is to set min-height: 0%; (the % unit must be specified, since unitless and px don't work) on the <table>'s parent element.
