The downloader will fetch and install the extensions specified in the configuration file. See ./extension-downloader --help for available CLI options.

Configuration

To configure extension-downloader, edit the config.toml file to specify which extensions you'd like to download. The configuration options include specifying the extension IDs (or names), the destination directory, and browser type.

Example config snippet:

[[extensions]]
# browser can be one of: "firefox", "chromium"
browser = "firefox"
# tilde (~) is expanded, anything else not
profile = "~/.mozilla/firefox/default"
# firefox extensions are referenced by name
names = ["ublock-origin"]

[[extensions]]
browser = "chromium"
profile = "~/.config/chromium"
# chromium extensions are referenced by their ID
# which can be obtained from the URL in the Chrome web store
names = [
    "cjpalhdlnbpafiamejdnhcphjbkeiagm", # ublock-origin
]

# Microsoft Edge on Windows
[[extensions]]
browser = "chromium"
profile = "Microsoft\\Edge"
names = [
    "cjpalhdlnbpafiamejdnhcphjbkeiagm", # ublock-origin
]

Note: Each extension is downloaded only once and then shared across compatible browsers.
