Why use NoScript?
For your sites you regularly visit, you will want to allow them permanent access. In order to change from temporary to permanent access, click the clock. The clock will change from large to small, denoting permanent access. This permanent setting is stored in your browser database, and will be retained the next time you start your browser.
Save your Preferences
From Addons Manager, NoScript, Preferences, NoScript Options, the top right has an option to export preferences. This will save a .txt file to your computer. I have exported my preferences but have not imported them.
