About chromium-web-store
chromium-web-store is an open source browser extension that adds Chrome Web Store extension installation and semi-automatic update functionality to ungoogled Chromium and other Chromium forks that lack native Chrome Web Store support. It shows available extension updates via a toolbar badge, and also supports updates for extensions not listed in the Chrome Web Store if developers host a compatible update manifest. To use the extension, users must adjust specific browser flags: ungoogled Chromium requires setting the #extension-mime-request-handling flag to "Always prompt for install", while other supported forks need to enable the "Always download CRX files" option in extension advanced settings. Some extensions may not update until the browser is restarted, and users may see CRX installation errors if required flag settings are not configured correctly.
