To load websites faster, you will firstly need to use Firefox. Then you will need to download the QuickJava extension to Firefox.
Once you’ve added the extension, restart the Firefox browser. Click Open menu and Customize to open the window below. That should include the QuickJava buttons, which you can drag onto the Firefox toolbar. Drag all those buttons to the toolbar, and click Exit Customize. Then your Firefox toolbar will include the QuickJava buttons.
Now click on the Open menu button > Add-ons and press the QuickJava Options button. Alternatively, right-click on one of the QuickJava buttons and select Options. That opens the window in the shot below.
So QuickJava is a great add-on to speed your browser up with. You can find further details for it at the QuickJava blog.
