The popular Firefox browser is available in many different editions. Every edition has its own release channel and has different features, stability, target audience and OS and add-on compatibility.

Firefox Nightly for Windows now features a new Reader mode, which might be familiar to Firefox users of mobile devices.

In some cases, e.g. when YouTube detects that something is wrong with your browser, it might switch automatically to using Flash for videos instead of HTML5, but there is no way to control this yourself.
