When I develop web-based applications or websites, I need to test browser compatibility to make sure that every browsers like IE, Firefox, Opera, Chrome, and Safari display the expected result.
I find that it is difficult to test across many browser because I have to open many browser or window at a time. Then, have to press [ALT + Tab] to switch between browser and [CTRL + R] to refresh it to see the result.
Now I'm looking for an easier and faster way to test my website, maybe there is a software that can contain many in one browsers, and you can switch them only by pressing a single click to what browser you want to use.
