Furthermore, it can rebuild the cookie, if you removed it from your computer, unless you have removed them from all locations and reset the local storage. So, even if you have deleted the standard and flash cookies, Evercookie implemented website can still identify you.
According to the developer,
It stores data in:
- Standard HTTP Cookies

- Storing cookies in Web History
- Storing cookies in HTTP ETags
- Storing cookies in Web cache

Here I am talking about a plug-in for Firefox called ‘Anonymizer Nevercookie’. Its developer claims that it can prevent Evercookie from storing data in the browser. It does this by creating a new profile for the Firefox’s private browsing mode and removes Evercookie from all locations after the browsing session.
If you’re concerned more about your privacy, you can try this plug-in from here. After installing the plug-in, launch the Firefox browser and go to Tools - Start Private Browsing.
A new browser window will open. It will be branded with a blue Navigation Menu bar. Use this window for your private browsing session. To leave private browsing mode, close the private browsing window in the parent Firefox window, go to Tools - Stop Private Browsing.
