How to view IndexedDB content in firefox

Question

I've been playing with IndexedDB in Firefox (Ubuntu)

Is there any way to visualize IndexedDB databases contents ? Or do I have to do it programmatic-ally ?

Answer 1

Bleeding edge Chromium builds reportedly allow you to view IndexedDB content in the Resources panel of the Chrome devtools, but only I know of one way to view Firefox IndexedDB content non-programmically and that's to load the .sqlite file directly.

Firefox's IndexedDB .sqlite files are located at /Users/{USER}/Library/Application Support/Firefox/Profiles/{PROFILE}/indexedDB on OS X and should be C:\Users\{USER}\AppData\Roaming\Mozilla\Firefox\Profiles\{PROFILE} on Windows.

I use the excellent (and free) Firefox tool SQLite Manager, which is cross platform.

One thing to keep in mind however is that the contents are often stored as binary blobs and are likely not to be human readable. Keys are stored as text however so they should be able to be read by hand.

Update Although local files remain a great way to view IDB databases and stores, Chrome does now have great tooling available in the Resources panel.

Answer 2

I just downloaded the IndexedDB Browser add-on for Firefox. It works well. Once downloaded it is located in:

Tools > Web Developer > IndexedDB Browser

https://addons.mozilla.org/en-US/firefox/addon/indexeddb-browserupdated-fix/

EDIT: Since Firefox 26 the files for IndexedDB have moved from

{PROFILE}/indexedDB/

to

{PROFILE}/storage/persistent/

The current Version (0.1.4) does not handle this change. However it can be easily solved with a symbolic link.
