Discussion Overview

The discussion centers around the files and folders used by Firefox to store the last session in the event of a crash, with a particular focus on retrieving session data from a backup. The conversation also touches on similarities with Flock, a browser similar to Firefox.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant expresses curiosity about accessing a backup of Firefox's session data from a few months ago.
  • Another participant suggests that the relevant file is likely named sessionstore.js.
  • A subsequent post confirms that sessionstore.js is indeed the correct file and notes that it is saved in JSON format.
  • A later reply reiterates the identification of sessionstore.js and confirms its functionality in restoring the session.

Areas of Agreement / Disagreement

I'm just curious if I want to look at a backup I made on my external hard drive a few months ago of a certain configuration. If I want to pull up what Firefox had then on the restore session?

I know Flock is pretty much the same as Firefox, so if anyone knows anything about that either?

sessionstore.js if I recall correctly.
 
Also another note, the file is saved in JSON format.
