These days there are several free software browsers available. It's important to use browsers which support media formats not encumbered by patents. This page documents browsers which are highly featured, have graphical interfaces, and support free formats.
Contents
Free browsers, caveat free
GNU IceCat
GNU Icecat is a free browser based on Mozilla's Firefox. It contains several privacy enhancements and includes extensions like LibreJS turned on by default.
It is sometimes a bit behind Firefox in releases.
Chromium
Chromium is a free browser. (It should *NOT* be confused with Google Chrome, which shares a codebase with Chromium but is not free software.)
Iceweasel
Iceweasel is really just Firefox, but rebranded by Debian to be free of trademark issues.
Browsers that might seem free, but are not
Firefox
Copyright isn't the only thing that can be used to grant or take away the four essential freedoms. The FSF's Free Software Definition contemplates the possibility of it happening outside copyright when it says "we can't possibly list all the ways that might happen" and goes on to say that if there were one that "restricts the user in an unusual way that copyright-based licenses cannot, and which isn't mentioned here as legitimate, we will have to think about it, and we will probably conclude it is nonfree."
Mozilla has found a clever way to take away freedom #2 using trademark law instead of using copyright law. As the FSF covers in their Free Software Definition, all four freedoms must be available on both a commercial and non-commercial basis. Mozilla's trademark policy serves to limit Freedom 2 (the freedom to make exact copies) to gratis distribution only, making the software nonfree.
It is as if Firefox were under a non-commercial license. It's achieved through means outside of copyright, but the net effect is the same. Fortunately, their method leaves a loophole open for derivative works such as GNU IceCat to escape this and this is exactly what they do.
Browsers to avoid
These browsers are entirely nonfree. You may hear recommendations to use them. Please avoid them, and instead use one of the above browsers.
- Google Chrome
- Safari
- Internet Explorer
