SQLite is a powerful database that works behind the scenes of Mozilla Firefox Internet Web Browser by storing its history, bookmarks, the anti-phishing elements, etc. Aiming to provide optimum performance, data is kept secured and searching becomes faster by using SQLite. A little tweak can provide quality output from parts of Mozilla Firefox, although there are a couple of drawbacks with SQLite. It takes quite a large amount of disk space and unless and until modified, Mozilla Firefox can't compact the database part. After downloading SQLite from specific sites, some little adjustments need to be made in Mozilla Firefox so that the size of the SQLite decreases.
