Hack #4. Prevent a User Script from Executing
You can disable a user script temporarily, disable all user scripts, or uninstall a user script permanently.
Once you have a few user scripts running, you might want to temporarily disable some or all of them. There are several different ways to prevent a user script from running.
Disabling a User Script Without Uninstalling It
The easiest way to disable a user script is in the Manage User Scripts dialog. Assuming you installed the Butler user script [Hack #1] , you can disable it with just a few clicks:
From the menu bar, select Tools → Manage User Scripts…. Greasemonkey will pop up the Manage User Scripts dialog.
In the left pane of the dialog is a list of all the user scripts you have installed. (If you've been following along from the beginning of the book, this will include just one script: Butler.)
Select Butler in the list if it is not already selected, and deselect the Enabled checkbox. The color of Butler in the left pane should change subtly from black to gray. (This is difficult to see while it is still selected, but it's more useful once you have dozens of scripts installed.)
Click OK to exit the Manage User Scripts dialog.
Now, Butler is installed, but inactive. You can verify this by searching for something on Google. It should no longer say "Enhanced by Butler" along the top. You can reenable the Butler user script by repeating the procedure and reselecting the Enabled checkbox in the Manage User Scripts dialog.
