When you right-click on the tray icon in your taskbar, the menu to your right will appear (initial settings shown.)

You are, of course, free to change the settings.

If you want to do some research on the web and you do not want the traffic in your cache, you can temporarily "Disable Webcelerator."

Note that the Help option will take you to the start page of these files.

Please familiarize yourself with the various items on the left for complete information on all facets of the right-click menu.
