Install an unreleased version
Sometimes, you want to use a version not available on the stores yet, or a beta version because a developer asked you.
If you’re really sure you want to do it anyway, you can follow these steps:
For Firefox
- Add the beta version from the Firefox Add-on site
For Chromium-based browsers (Chrome, Vivaldi)
This version WILL NOT be updated automatically by your browser.
- Download the last pre-release CRX file
- Go to your browser’s extension settings page
- Chrome:
chrome://extensions/
- Vivaldi:
vivaldi:extensions
- Brave:
brave://extensions/
- Enable the developer mode (toggle on the top right corner)

- Drag ‘n drop the CRX file to this page
- Accept to install it
Install the last work in progress version, should be stable, but not ready for production (Really not recommended)
- Download the last version of the source code
- Unzip this file
For Chromium-based browsers (Chrome, Vivaldi)
- Follow the steps 2 and 3 of the previous section
- Select the wallabagger folder (containing the manifest.json file)
For Firefox (temporary installation)
- Go to your browser’s debugging settings page
about:debugging
- Open
This Firefox
- Click
Load Temporary Add-on...
- Select the
manifest.json file from the wallabagger folder
For Firefox for Android (temporary installation)
- Set up your computer and Android emulator or device
- Connect your phone to your computer using USB
