From Addon Store¶
It is recommended to install the extension from the Firefox Add-ons website.
From Development Artifacts¶
You can download and install the latest build artifact from GitHub Actions builds.
These are development versions that may be unstable and are not signed, so you will need to configure Firefox to accept non-signed extensions or just load it temporarily. It is generally not recommended to use them, unless you are testing a specific unreleased feature.
You can read the instructions for the installation from source in the extension README file.
