Firefox on Android - Cookies, Permissions & Form History

Web History, Visits, Bookmarks & Search Terms

Downloads, Top Sites & Recently Closed Tabs

Did I mention that browsers have a ridiculous amount of data for an examiner to find? In this post we'll look at Cookies, Permissions and Form History. I hope you're hungry!

All relevant databases can be found generally in the following path:


The "default" profile will have it's own unique guid of sorts.


The Cookies database resides at the path:


There is only one table in the database so can't go wrong there, it's called "moz_cookies". A few columns of interest include:

  • lastAccessed - last accessed timestamp in Unix Epoch microseconds
  • creationTime - created timestamp in Unix Epoch microseconds
  • host - webpage that is hosting the cookie
  • name - name of the actual cookie being used
  • value - value that the cookie contains
  • expiry - expiration timestamp of the cookie in Unix Epoch seconds
  • path - path of any extra associated files (not entirely sure but did see some references to JavaScript files)
Get the query here, see the results from Josh's test image below:

Permissions was one of the harder items to test. It was difficult to find good webpages that would throw up the permissions pop-up on mobile. Regardless, I could make some inferences but more future testing probably is needed. You can find the database at the path:


The table is called "moz_perms" and the columns I pulled out were as follows:
  • modificationTime - timestamp of the modification of the specific permission
  • origin - the webpage the permission is coming from
  • type - the actual permission name (ex. "autoplay-media-audible" or "storageAccessAPI")
  • permission - status of the permission
    • 1 = Allow
    • 2 = Block
*Note* There may be more granular permission statuses but I haven't been able to produce them at this stime.
  • expireTime - expiration timestamp of the permission
You can use the query from my Github to produce similar results as below:

Form History

Form History or autofill are items entered into fields in forms and saved for potential future use. It can be useful in seeing what a person may be entering as well as how often. The Form History database file can be found at the following path:


The main table inside is called "moz_formhistory" and we can find these columns useful:
  • firstUsed - first time that value and field have been used in Unix Epoch microscends
  • lastUsed - last time that value and field have been used in Unix Epoch microscends
  • fieldname - identifier for a specific field (not sure if there is a standardized list out there somewhere but I do see "ts" that looks to be a timestamp)
  • value - actual value entered into a form field
  • timesUsed - a count of how many times that value and field have been used
  • id - unique identifier for each entry
Query is here, sample output below:

These three parsers are also now available in ALEAPP, happy hunting!
