What is cookies.sqlite? Should I remove it?

Cookies.sqlite is the piece of cookie storage for Mozilla Firefox browser

cookies.sqlite is a legitimate Mozilla Firefox data file that stores cookies in the Firefox profile folder. A cookie is a small piece of information that is sent by visited websites and stored on the user's computer. Thus, this file might include information related to login details, session data, and preferences, such as your language or location.

This “shared memory” file is created by the search engine every time the user starts browsing and deletes automatically, as soon as the browser is closed. cookies.sqlite is used for the temporary storage of cookie updates and helps keep people logged into a particular website, authenticating them, and similar activities.

What is more, this file might also store personally identifiable information, such as your name and surname, address, telephone number, etc. However, the collection of this data might lead to various privacy-related issues.

When Firefox works with SQLite databases like cookies.sqlite, it creates temporary files like cookies.sqlite-wal and cookies.sqlite-shm. When you exit Firefox, it should reconcile and remove the two temporary files. But it doesn't happen every time.

If the temporary files are still there after the browser closes – you can delete them.
