Which is better, Mozilla Firefox or Google Chrome?

It depends, better in what term?
As I am a user who has tendency to open dozens of tabs, I've experienced both pro and cons for Chrome and Firefox.

Chrome is faster than Firefox when browsing with single or low number of tabs. It's simpler too if you somehow need to free up some memory since Chrome separate the process for each tab (you can check on Task Manager). But, if you have a lot of tabs, Chrome started to become uncomfortable. You can notice that the tabs getting smaller to give spaces for other tabs to the point that the tabs is way too small for even an icon and you have no way to identify which tab is which.

Firefox is slower (or so what people said), yet it handles multiple tabs quite well. It's looks like Firefox favoring the "Multiple Tab" users. They limit the tabs minimum size and give them scroll effect, we can see list of tabs from a drop down menu, and they add "Tabs Group" feature since v4.0 (really love that updates). When handling multiple tabs, Firefox is faster than Chrome (I once tested it with 50 tabs on each). But the problem arises when you need to free up some memory. Since Firefox only use 1 process, it will be though to check which tab is eating the most memory. On the light side, we can easier check how many memory it used from Task Manager.

Firefox do have other positive value, which is customization. Fire fox has a lot of way to customize it looks. From grouping your tabs, add and remove toolbar icons, reposition the toolbar and it's icon, give a theme to your Firefox, to the most important one, add-ons. With add-on, you can add extra functionality to your Firefox which ultimately will make certain tasks easier.

So, in the it depends on what you need, single and fast browser? or Heavy yet easily customizable and tough browser? (though I don't think Firefox is that heavy)

As for me, I use mostly Firefox since I'm using a lot of tabs (I have a record of 120 open tabs). I also like the add-on on Firefox.
But if you only want to use it as a simple browser, use chrome.
