Is There Any "developers Only" Browser? For website testing purposes

[greenpeace 0]

I came across a website siteshots.org which takes a snapshot of a website using different browsers, versions, screen resolution, script functions etc. But it only gives an image of the index page and just says "how it looks", not "how it works". I am thinking about a developers only broswer that can simulate all popular browsers, different versions, screen sizes, OSs, mobile view etc.I know, with a collection of different tools, I can do it. But I need all, at least most, of these features in a single software. Any suggestion?

The most you'll be able to make is a browser that uses the Gecko, Webkit and Trident engine, but you'll only be able to get Gecko and Webkit on other platforms. As for the Presto engine, i don't think it is publicly available, therefore you won't be able to mimic Opera. If i'm not mistaken, there is a Firefox extension out there that allows you to load the Trident engine within Firefox on Windows, but this extension will not work for other platforms.

You can use IE tab with firefox, to simulate internet explorer which uses the trident rendering engine. You're gonna have to install Opera and Safari or some sort of Webkit engine to check up on the webkit rendering. I wouldn't really check up on those rendering engines much, few really use Safari on a windows machine, and I doubt most of your viewers are Apple product users, but if they are you can just install Chrome or Safari. There's a lot of webkit browsers as well. You can also install Seamonkey instead, which is a streamlined version of firefox. There are other browsers than can switch between different rendering engines. I forgot the name, but it runs Trident, Webkit, and Gecko. You can switch up to anything that you want. However you might wanna try checking it fixing quirks in each one itself, since its not always the engine but the browser. There's nothing to test with Opera, you're gonna have to install it yourself, since Presto isn't used on anything else. Opera has got a tight company of its own. I still don't know how that makes money, but I'm not gonna talk about it, its basically one of the biggest free software companies that isn't open source.

There is a popular application named IE tester and it is used to test websites in different versions of Internet Explorer. You can install multiple versions of Firefox or at least use the portable editions of it. Google Chrome is the one thing I keep updated all the time, so I'm not very sure of how you can get older versions of it, but Chromium, which is essentially the same as Google Chrome, is available on Linux repositories so you can select the package that you want to install and perhaps keep different versions in different virtual machines. Getting around licensing requirements by using open source software is one of the reasons why open source software developers can be likened to Good Guy Greg.
