For the second website it is as follows:
Speed
The first and foremost factor that determines a browser's success is speed. Although Firefox has always been working on improving its speed (and it has) but when it comes to Chrome, it has been fast from the very beginning. Its not that Firefox speed is not good enough, but when it comes to comparing it with Chrome's lightening fast speed, Chrome wins hands down.
Another factor that adds up to speedy browsing in Chrome, is its auto fill feature in the address bar. Just type the first few letters and Chrome will find it for you, all you need to do is hit enter...pretty much like Google's instant search.
Bloat
Browser bloating is a browser's ability to use system's resources to get bigger. When it comes to memory use tests, Firefox has always had an upper hand. But lately a lot of users are complaining slow-downs caused due to browser bloat. Although, Chrome uses a lot of memory too, but when compared with Firefox, browser slow-downs complaints are comparatively less.
Extensions
This is one area, where Firefox has always been better than Chrome. If there is anything that you would like your browser to do, Firefox's add-ons (extensions) has it all. It is their extensive extensions ecosystem that has users coming back for more.
Chrome on the other hand has an impressive gallery of extensions, but let's not forget that Firefox is developer's favorite, so if you looking for more options in terms of browser applications, then Firefox it your answer.
Firefox has an excellent plugin called firebug which is an excellent tool to debug webpages. It helps in debugging JavaScript code as well as trying out various CSS rules dynamically on a page. In this plugin you can clearly view all the GET and POST requests that are sent from the page. So basically Firefox browser is an invaluable tool for developers.
Ctrl+T
Browsing is all about hitting Ctrl+T and opening endless numbers of tab hoping that your browser will be able to sustain the information overload that you are about to impart on yourself. Before we compare both the browsers in this particular area, you should know that if you are a Linux user, chances are that Firefox will pretty much suck if you open more than 5 tabs. But it works beautifully with Mac or Windows.
On the other hand, Chrome has no inhibitions towards Linux and works great with Mac and Windows as well. If you are anything like me and have numerous tabs open then Chrome is more stable as opposed to Firefox because chrome splits all open tabs into different processes and thus a rogue plugin crashing in one of the open tabs affects only that tab in Chrome and thus not bringing down the entire browser.
In the end it is your choice to choose which browser you want. I have used both but I prefer Chrome as I use it more frequently than Firefox.
But Firefox is way better for games than Chrome.
