To support WebGL, these versions are recommended.
Older versions of these browsers (especially those more than five years old) and less commonly used browsers should also work for the most part, but might not be able to properly display the interface or provide full functionality compared to modern browsers.
Other than a modern browser, to view the molecular structure of entries using jV or Jmol, the most recent version of Java is required which can be downloaded here. Check here whether you have the latest version installed.
To use molmil, it is also recommended to have updated video drivers (drivers newer than 2010-12-31 should be sufficient, but the latest drivers are recommended for better performance).
