This is a free browser on the Gecko engine, developed and distributed by Mozilla Corporation. It emulates multiple XR devices, so you can select which one you want to test. I'd be particularly interested in an emulator that runs on Windows O/S unit test environments. After that you will see your website in the mobile view mode like this. Since javascript is slower than native code, one would expect slower boot times for the Linux, but it boots amazingly fast. It includes all of the most popular browsers, like Chrome, Firefox, and Safari, along with tons of other browsers that may sound unfamiliar, like Flock, SeaMonkey, and Iceape.

Please note that everything you modify in this VM will be discarded, nothing is saved. This helps developers or QA testers to run a quick check of how their code appears on Firefox, as part of their development lifecycle. For example, a Firefox emulator will provide the same look and feel of an actual Firefox browser when a website is opened on it.
