Just run Cheat Engine. Click the little color changing button on left top corner and choose:
Firefox: FlashPlayerPlugin_11_4_402_265.exe (The second one! Not the first.)
Google Chrome: Usually its the last Chrome.exe, yet there's no sure way to know it. So you are going to have to try all of them.
When you found it, press Open.

Hit Enable SpeedHack, adjust the bar to about 200. But before pressing apply, go to your research page (ingame). Then hit confirm.

Note that none town buildings will not be ready, don't even bother clicking them.

1. Go to your game and open up Charles.
2. In the game, send a gift to a random person.
3. Go back to Charles and find this folder: [You must be registered and logged in to see this link.]
4. Next go fb -> appRequest. Set breakpoint to appRequest.
5. Go back to game and send another gift. This time you will get a popup from Charles.
6. Press Execute twice. Go back to game and continue the progress.
7. Now, you got another popup? Good. In order to send yourself a gift, find out your profile ID. Here's a link for it. [You must be registered and logged in to see this link.]
8. Now that you know your ID. You'll notice a external_request_key and a whole bunch of numbers. What you want to do is change the number behind "_". For example: 114959058653243_YOURIDHERE.
9. Click Execute twice. When you did it correctly, you should receive a gift from yourself.
