Unix/Linux

Mozilla

All versions of Mozilla (from around 0.94) should display XHTML + MathML documents by default. MathML support is part of the core rendering engine in this browser.

You may need to install additional fonts (if so, a dialog box will alert you when you first view a page containing mathematics).

• On Linux with Xft-enabled builds, you should install the TrueType TeX fonts and Mathematica 4.1 fonts (repeat: 4.1). C.f. these instructions.
  
  
• On Unix/Linux with Xft-disabled builds (i.e., with X11core fonts), you should install the Type1 TeX fonts and Mathematica 4.1 fonts (repeat: 4.1) in PFA and PCF formats. C.f. these instructions.
  
  

Netscape

Netscape from Version 6 onwards is based on a version of Mozilla, so the notes above apply. Don't use Version 6.x as it is very slow; Version 7.x should work without problems.

Amaya

Amaya should just work out of the box, it includes support for XHTML and MathML by default. However its rendering is not up to the quality of MathPlayer or Mozilla.
