If you are not a licensed user of BlackLight, you can request a trial licence on the BlackBag website. Use the REQUEST TRIAL button on the BlackLight page, fill in your personal information, such as first and last names, phone number, city, email, and so on, and click on SUBMIT. You'll get your trial key and product download links via email, so make sure you have submitted your real email, ideally a government or business one.

Now you need to get a folder with Firefox files for analysis. If you have a Windows XP system, look here:

C:Documents and Settings\%USERNAME%Application DataMozillaFirefox

If you are dealing with a Windows Vista system (or later), look here:

C:UsersadminAppDataRoamingMozillaFirefoxProfiles\%PROFILE%.default

Among other files, you'll find a bunch of valuable SQLite databases. These databases contain information about browsing history, downloads and so on, and BlackLight will help us to extract and analyze this data.
