hummingme/kahuna: Browse, edit and manage IndexedDB databases in Firefox and Chromium browsers

Posted on by


Kahuna is a browser extension for Firefox and Chromium based browsers to manage IndexedDB databases. It can be used to create databases and modify their structure, as well as to view, query, edit, import and export the data they contain.

Kahuna at work

  • signals with its icon in the browser’s address bar when IndexedDB databases exist for a visited website
  • displays lists of the found databases and tables (aka object stores)
  • can create new databases and delete existing databases
  • tables can be created and deleted, the indexes of tables can be modified
  • displays the data of a table page by page and enables the editing and deletion of data records
  • Filters can be configured and combined for all data fields to display or export a selection of the data contained in a table
  • imports and exports databases in dexie format
  • imports and exports tables in dexie, json and csv format, as well as selected data records in json and csv format
  • enables the entry and execution of arbitrary JavaScript code to modify databases, tables or data as desired

Please download and install the extension from the Chrome Web Store for Chrome and Chromium based browsers such as Edge, Brave, and Opera, and from the Firefox Addons Page for Firefox.

Sorry, the user documentation is still work in progress, but will be available here soon!

Build and Install from Source

git clone https://github.com/hummingme/kahuna.git
cd kahuna
npm install 
npm run release firefox & npm run release chromium

Afterwards the packages firefox.zip and chromium.zip are located within the build/ directory. The subdirectories build/firefox/ and build/chromium/ contain the unpacked extensions.

To install Kahuna on Chrome, follow this instructions for unpacked extensions.

With Firefox, the packed extension firefox.zip can be installed in ESR-, Developer- and Nightly releases after toggling xpinstall.signatures.required: false in about:config. Installing the unpacked extension is also possible by visiting about:debugging#/runtime/this-firefox and using Load Temporary Addon, but this must be repeated after each restart.

For bug reports and feature requests please open an issue in this repository.

The development does not take place on github.com, but in a private repository. Pull requests are welcome too, but they will not be integrated here. Instead, after review and if appropriate, transferred to the private repository. For more complex code contributions, please contact me in advance.
