Web Browser for Viewing Documentation and Help
By default, documentation is shown in the Documentation window and context help in the Help window integrated in the COMSOL Desktop. If you prefer to use an external browser, you can specify this on the Help page of the Preferences window.
You can choose your preferred web browser in two ways:
In the Executable field on the User Interface page of the Preferences window.
If no browser executable has been specified, the browser to use is determined by the script browser in the bin directory. The variable BROWSERS in this file contains a list of web browsers that are available with the supported Linux versions in order of preference. Edit the file in any text editor to adjust it for your preferred web browser. To make a specific browser the preferred web browser, put it first in the list.
