Manual installation

Briefmark targets Chrome, Edge, and Firefox on desktop, and Firefox for Android on mobile. Chrome and Edge are available through the Chrome Web Store. Firefox is available from the signed download below and from Firefox Add-ons when the listing is available.

Download the current approved installer here, then follow the browser-specific instructions. Chrome and Edge share the same public ZIP; Firefox uses its signed XPI.

Download for Chrome (0.5.4)

Download for Edge (0.5.4)

Download for Firefox (0.5.4.1)

Browser File to download Instructions
Chrome on desktop briefmark-VERSION.zip Install in Chrome
Edge on desktop briefmark-VERSION.zip (shared with Chrome), or briefmark-VERSION-edge.zip when provided Install in Edge
Firefox on desktop briefmark-VERSION-firefox.xpi Install in Firefox
Firefox for Android briefmark-VERSION-firefox.xpi Install on Android

VERSION is the release number in the filename. GitHub releases are a secondary archive. GitHub’s Source code archives and the firefox-source.zip and firefox-unsigned.zip files are for development or review, not normal installation. Firefox needs a Mozilla-signed .xpi; renaming a ZIP does not make it installable.

Manual installations need manual updates. Follow your browser’s guide below to keep your saved feedback when updating. Briefmark stores feedback in the browser profile where it was collected; it does not sync between browsers or devices.
