MyWords Firefox Extension is a handy extension that helps save your time by making your favorite words and phrases always available, just a few mouse clicks away. It can save any number of your favorite words and phrases, and use XML import and export functionality to transfer your word database between computers. Select the phrase you just typed and use a right mouse click to access the "MyWords" menu and add it to your favorite words database. You can then right mouse click in any text input area and select one of your saved words to paste at the current cursor position. A keyboard shortcut can be used to either paste the last favorite phrase you have just used or, after you've typed the first few letters, autocomplete your phrase with one from your saved phrases database.
