Install LibX Toolbar


The Firefox version of LibX works with Firefox on Windows, Mac OS X, and Linux.

Firefox may display a message that reads "To protect your computer, Firefox prevented this site ( or from installing software on your computer." Since some browser plugins could potentially be malicious, Firefox prompts with this warning when you attempt to install a new add-ons to it. The open source LibX add-on was developed by Virginia Tech and is in use by many universities around the world, and we believe it does not pose security or privacy risks. If you wish to use the LibX add-on, you will need to tell Firefox that you trust the source of the program to allow it to be installed.

To continue the installation after seeing this warning, press the button labelled "Edit Options..." that has appeared near the top of your browser window and click "Allow" to add or to the list of websites from which extensions may be installed. Then click "OK" and visit the above "Install" link again. After the installation is completed, you will need to restart your browser for the add-on to take effect.


LibX Preferences

Libx Preferences allow you to custom the links and functionality in the LibX toolbar. The General Preferences tab allows you to specify if the link opens in a new window or tab; while the Context Menu tables allows you to indicate which resources will be offered as links after right clicking.
