Why I use Firefox
No, it is not about the tabs, blockers, and extensions. I use Firefox for a political reason. I use Firefox because it is Open Source software. The browser, for me, is my own little window to the web. Through it, I can see a vast diversity of different things. Why should I let a corporation define how I will be able to see things through this window? I want to know that I have control over how things are shown to me. Not that I really care how the rendering engine in Firefox works, but it’s a good feeling to know that I could if the need arises. In an Open Source browser, the masses define what they see, and not a a single entity.
There are other open source browsers out there, like Konqueror, that should be mentioned as well. Check out the full list to find out which browsers are open source.
