Browser Extensions

The Chrome and Firefox extensions inject a small Mergify panel into every GitHub pull request you open. The panel surfaces the most common actions without typing commands and shows Mergify context (queue state, stack position) directly in the pull request. Use them when you want to:

• Enqueue a pull request as soon as you review it.
• Quickly dequeue without context switching.
• See at a glance whether the pull request is already in one of your queues.
• See a stack’s chain and revision history without opening the CLI.

The dashboard keeps the canonical links to the Chrome Web Store and Firefox Add-ons listing so you always grab the signed builds.

1. Sign in to the Mergify dashboard.
2. Open Settings → Browser Extensions in the left navigation.
3. Pick Add to Chrome or Add to Firefox.

1. Click Add to Chrome from the dashboard page.
2. Confirm the permissions in the Chrome Web Store dialog.

1. Click Add to Firefox from the dashboard page.
2. Approve the requested permissions in the Firefox Add-ons prompt.

After installation, reload any pull request on GitHub. A Mergify toolbar appears near the GitHub merge box and displays queue-specific controls:

• Queue places the pull request into the selected merge queue with one click.

• Dequeue (available when the pull request is already in the queue) removes it without typing slash commands.

For repositories using Stacks, the extension renders the Mergify Stacks panel inside the pull request. It shows the full chain of stacked PRs, highlights where the current PR sits, and includes the revision-history timeline so you can see how each commit evolved across pushes without leaving GitHub.
