I know the information is supposed to be at data/data/org.mozilla.firefox/ but I cannot seem to view/access them.

My device is rooted, and I've checked device storage as well as external storage, using multiple file browsers.

Specifically I'm trying to find where it stores the information that it saves for the top sites tab.

  • Have you looked at /data/data/org.mozilla.firefox/? Your profile should be under /data/data/org.mozilla.firefox/files/mozilla/

    Before you ask for the next app, here's a recommended reading: Where Android apps store data?

  • I only asked because, despite it already being said elsewhere, the location given doesn't show the data for me, even though I'm on a rooted device. The suggestion by Ankush to try accessing from with Firefox itself does work, but that still leaves the mystery as to how I can access those files for editing/etc. Nov 25, 2015 at 22:00

    Can you give is the result of su -c "ls /data/data/org.mozilla.firefox" or su -c "ls -l /data/data/"? Use a terminal emulator app for that. Also, use @ to notify someone, such as @Izzy.

    @vertigoelectric though you're using root capable apps, you might have to enable "root mode" for them. I vaguely remember ES had a setting for that (it's quite a while ago I've used it last). Often that's disabled for security reasons (so you don't accidentally do something "unlucky").

Apps on Android store their data in /data/data/[package_name], so Firefox should be keeping its data in /data/data/org.mozilla.firefox.

NOTE: To access this directory you need root access.

Use file:///data/data/org.mozilla.firefox/ from inside Firefox to access the folder (without root). This work because Firefox owns the folder (see the comments)

  • Does file:///data/data/org.mozilla.firefox option work without root?

  • @SarpSTA, I tested it on FF 40.0, and because Firefox owns the directory, it does work.

  • @Firelord Yeah I figured it would. Just the fact that it was given after the notion of requiring root access it kind of confused me.

  • I see. I am able to view the files from inside Firefox as suggested. However, I need to be able to access these files from outside of Firefox, particularly with Tasker. My device is rooted, so I'm not sure why I cannot access these files... Nov 25, 2015 at 21:49
  • @vertigoelectric Are you using a file explorer that supports root? The default file explorer installed on your device will likely not display any of the / (root) directory on your device aside from the internal and external storage. Something basic like ES File Explorer should do the trick!
