Where can I find Shumway technology demos?

The live demos are located at http://mozilla.github.io/shumway/ (and also mirrored at http://www.areweflashyet.com/shumway/). These is HTML5 web application and does not require any extensions or add-ons installed.

Can I install Shumway extension for Firefox?

The Firefox extension is provided for the developers and tester -- end user shall use Firefox Nightly to try it (see below). The extension is published at http://www.areweflashyet.com/shumway/extension/firefox/shumway.xpi and automatically updated. The extension requires click-to-play enabled (for Firefox 21+) and Flash plugin set to "Ask to Activate" (for Firefox 23+).

It is possible to configure the extension (e.g. when the Flash plugin is not installed) to ignore click-to-play settings and always show the Shumway player. See https://github.com/mozilla/shumway/wiki/Debugging-and-Configuring-Shumway#using-the-extension for more information.

I heard Shumway is a part of the Firefox Nightly. How can I use it?

The Shumway code is disabled by default (see bug 904346). You have to enable it by opening the web browser at about:config and changing the preference shumway.swf.whitelist to "*" and shumway.disabled to false.

The Nightly downloads can be found at http://nightly.mozilla.org/.

I have a Flash movie that does not work. Can I submit it as an issue?

Yes, but you will be requested to submit the source code. It will be really helpful, if the problematic movie is reduced to the small test case.

I'm too lazy to build the project. Can I still test/use it with my SWFs?

The build Shumway code (iframe viewer, shuobject, and shell) is published at https://github.com/mozilla/shumway-dist and also available via npm/bower. shuobject will be the simplest way to deploy viewer with your SWFs (e.g. Install and use built Shumway from Bower). Please notice that cross-domain loading rules will apply.

You can use the inspector located at http://mozilla.github.io/shumway/examples/inspector/inspector.html or http://www.areweflashyet.com/shumway/examples/inspector/inspector.html. See Accessing SWFs from Remote Sites for details.

How can I make sure that Shumway is responsible for rendering frames?

Shumway will add "Shumway" in a small bubble at the bottom-right corner of the Flash content. This bubble allows you to revert to the native plugin if need be; it also allows you to report problems with Shumway. See #764.

For non-visible Flash content, there is currently no way to tell if Shumway is responsible. See #1292.
