While jQuery might run without major issues in older browser versions, we do not test jQuery in them and generally do not fix bugs that may appear in them.
Similarly, jQuery does not fix bugs in pre-release versions of browsers, such as beta or dev releases. If you find a bug with jQuery in a pre-release of a browser, you should report the bug to the browser vendor.
HTML5, SVG, jQuery, Canvas, CSS, new browsers, old browsers, RequireJS, EaselJS, mobile, and more – GSAP complements them perfectly. Use your favorite tools without jumping through endless hoops to ensure compatibility. It even accommodates various transforms (scale, skew, rotation, x, and y) in modern browsers, plus IE starting from version 6 without requiring clunky browser prefixes and hacks. We worry about compatibility so that you don’t need to.
Firebase is using web technologies such as HTTP, AJAX, XMPP, Web Push Protocol, WebSockets; which are supported by all modern browsers.
Supported browsers
Moment.js was designed to work both in the browser and in Node.js. All code should work in both of these environments, and all unit tests are run in both of these environments.
Currently, the following browsers are used for the CI system:
All web browsers have varying levels of support for fonts linked via @font-face.
Web Font Loader determines support for web fonts by using the browser's user agent string. The user agent string may claim to support a web font format when it in fact does not. This is most noticeable on mobile browsers with a "Desktop" mode, which usually identifies as Chrome on Linux. In this case, a web font provider may decide to send WOFF (Web Open Font Format) fonts to the device because the real desktop Chrome supports it, while the mobile browser does not.
The Web Font Loader is not designed to handle these cases and it defaults to believing what's in the user agent string. Web font providers can build on top of the basic Web Font Loader functionality to handle these special cases individually.
If Web Font Loader determines that the current browser does not support @font-face, the inactive event will be triggered.
When loading fonts from multiple providers, each provider may or may not support a given browser. If Web Font Loader determines that the current browser can support @font-face, and at least one provider is able to serve fonts, the fonts from that provider will be loaded. When finished, the active event will be triggered.
