The Tortoise and the Hare

There is a natural tension on the web with respect to browser engines. Every engine has their own set of priorities which define the level of investment that they choose to make and on which areas they choose to make it.

A developer naturally wants their experiences to be available to the widest audience possible and these differing priorities create an unevenness on the platform (a lumpiness) making it harder for developers to build experiences that work everywhere.

This section highlights where browsers are pushing and pulling on the platform.

Sprinters

This table is designed to show which browsers are pushing on the platform the most.

Adding features to quickly is not always desired because developers are unlikely to adopt those features in their sites or apps.

For a given year, if a feature landed in Browser X first, how many days it take on average to be available in Chrome Android and Safari. TTA (time to available).

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.

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.

Chrome: The Google Chrome UI for auto-complete request varies, depending on whether autocomplete is set to off on <input> elements as well as their form. Specifically, when a form has autocomplete set to off and its <input> element's autocomplete attribute is not set, then if the user asks for autofill suggestions for the <input> element, Chrome might display a message saying 'autocomplete has been disabled for this form.' On the other hand, if both the form and the input element have autocomplete set to off, the browser will not display that message. For this reason, you should set autocomplete to off for each <input> that has custom auto-completion.Chrome Android: The Chrome Android UI for auto-complete request varies, depending on whether autocomplete is set to off on <input> elements as well as their form.

Firefox: Before 77, Firefox didn't display the value of the label attribute as option text if element's content was empty. See bug 40545.Firefox: Historically, Firefox has allowed keyboard and mouse events to bubble up from the <option> element to the parent <select> element, although this behavior is inconsistent across many browsers. For better Web compatibility (and for technical reasons), they will not bubble up when Firefox is in multi-process mode and the <select> element is displayed as a drop-down list. The behavior is unchanged if the <select> is presented inline and it has either the multiple attribute defined or a size attribute set to more than 1. Rather than watching <option> elements for events, you should watch for change events on <select>. See bug 1090602 for details.Firefox: When Mozilla introduced dedicated content threads to Firefox (through the Electrolysis, or e10s, project), support for styling <option> elements was removed temporarily. Starting in Firefox 54, you can apply foreground and background colors to <option> elements again, using the color and background-color CSS properties. See bug 910022 for more information. Note that this is still disabled in Linux due to lack of contrast (see bug 1338283 for progress on this).Firefox for Android: Before 77, Firefox didn't display the value of the label attribute as option text if element's content was empty. See bug 40545.

Chrome: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.Chrome Android: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.Firefox: Historically, Firefox has allowed keyboard and mouse events to bubble up from the <option> element to the parent <select> element, although this behavior is inconsistent across many browsers. For better Web compatibility (and for technical reasons), when Firefox is in multi-process mode the <select> element is displayed as a drop-down list. The behavior is unchanged if the <select> is presented inline and it has either the multiple attribute defined or a size attribute set to more than 1. Rather than watching <option> elements for events, you should watch for change events on <select>. See bug 1090602 for details.Firefox for Android: Firefox for Android, by default, sets a background-image gradient on all <select multiple> elements. This can be disabled using background-image: none.Quest Browser: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.Safari: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.Safari on iOS: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.Samsung Internet: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.WebView Android: In the Browser app for Android 4.1 (and possibly later versions), there is a bug where the menu indicator triangle on the side of a <select> will not be displayed if a background, border, or border-radius style is applied to the <select>.WebView Android: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.WebView on iOS: border-radius on <select> elements is ignored unless -webkit-appearance is overridden to an appropriate value.
