What is an FXSNAPSHOT file?

FXSNAPSHOT files mostly belong to Firefox. FXSNAPSHOT files are used by the Firefox browser to hold a snapshot of the current session in an internal, compressed format.
They use GZIP compression to reduce file size and store session data efficiently.

The file contains compressed data representing open tabs and session state.

It is created automatically by Firefox for session recovery and debugging.

These files are not meant for regular editing and are managed internally.

An FXSNAPSHOT file stores a snapshot of the Firefox browser's state, including open tabs, browsing history, and settings. It is primarily used for restoring previous browser sessions after a crash or unexpected closure. The file format is compressed using GZIP, which reduces the file size and improves loading speed. These snapshots are essential for preserving the user's browsing context and ensuring a seamless experience even after interruptions. The files are automatically generated and managed by Firefox, and users typically do not interact with them directly. This file format is classified as Data File.

The file format determines how the data is stored in the file. Each file format has a unique extension and almost always a unique signature.
