Does the Juniper WSAM VPN use the Java plugin? Firefox 30 set most plugins to "Ask to Activate" instead of allowing all sites to use them automatically. This may not work in your situations. To switch the Java plugin back to "Always Activate" you can use the Add-ons page. Either: * Ctrl+Shift+a * "3-bar" menu button (or Tools menu) > Add-ons In the left column, click Plugins. Then you can edit this setting on the right side. Does that make any difference? You might need to launch a new window (Ctrl+n) or exit and start Firefox up again to see the effects.
