If you normally do a lot of copying from a web page of any kind that you've opened in the Mozilla Firefox browser, you have
got to get this Add-on: Auto Copy 1.0.1

You will love it! The reason is that normally you have to do the following to copy text from a web page to the Clipboard:

1 - highlight the text you want to copy
2 - right-click your mouse
3 - either press the C key or scroll to the Copy function using your down arrow key

(note: if you use CTRL+C after step 1, that's only 2 steps you need)

After you install the free Add-on (donation suggested if you find it useful - no, I don't know that guy from Adam!),
here is what is required to copy text from a web page to the Clipboard:

1 - highlight the text you want to copy

That's it! I cannot tell you how much time it's saved me as I have different uses for it other than sweepstakes (I'm creating custom, personal Access databases and am using it to populate the fields far faster than before) - I'm sure you sweepers can find a use for it. The main reason it saves time is you don't have to constantly fumble with the shortcut keys.
