# Prefill your coin address on faucet pages with JavaScript! [Firefox version]

Would you prefer to have your coin address prefilled on faucet claim & login pages?

If you love faucets you probably don't love those like *coinfaucet.info that forget your coin address every time you make a claim, requiring you to enter it over and over. This is annoying, and unnecessary.

What if I told you that you could use JavaScript to do this for you automagically?

I'm going to show you how.

Caveat: this technique requires the use of a browser extension, if you're against such things for any reason then read no further. Recording your cryptocoin public key (receiving address) in an automation script is perfectly safe because it's already in the public domain but you should NEVER record a private key, username, or password in such manner, such information is too private and powerful.

Prerequisite: Install Browser Extension

To run the Javascript a Firefox extension called Greasemonkey is required, grab that now:

Greasemonkey: https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/

1. Setup Faucet Page Script

Since the release of Firefox Quantum it is no longer possible to directly create User Scripts. To facilitate access and installation I created a script repository, the result is a much easier installation process (and a complete re-write of the code & this article).

We will use the Litecoin faucet page as an example to follow, here's my referral link: litecoinfaucet.info

1. Go to the LTC.info prefill script page
   
2. Click Install, review the summary then click Install
   
   
3. Click Greasemonkey in your toolbar, then click the script
   
   
4. Click Edit to open the script in a new tab for editing
   
   
5. Replace the value neuromancer with your coin receiving address
   
   
6. Press Ctrl+S to save (unsaved changes are indicated by *)
   
   

To see your LTC address prefilled visit litecoinfaucet.info

2. Reusing the script

Scripts for other *coinfaucet.info pages have been created, you will find them in https://openuserjs.org/users/neuromancer/scripts. To use them simply:

1. Install the script
2. Open the Greasemonkey menu
3. Click the script & click "Edit"
4. Replace neuromancer with your coin receiving address
5. Ctrl+S to save

Here are some more *coinfaucet.info referral links for you:
reddcoinfaucet.info
ethereumfaucet.info
dashfaucet.net
ripplefaucet.info
decredfaucet.info

Scripts for Moon faucet pages have also been created, just remember to tailor each new script by replacing neuromancer with your coin receiving address.

And here's some Moon faucet referral links:
moonbit.co.in
moonliteco.in
moondoge.co.in

Now head back to those faucets and STEEM ON!
