## Why Use the 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](/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](/stacks) chain and revision history without opening the CLI.

## Locate the Official Download Links

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](https://dashboard.mergify.com).
2. Open `Settings → Browser Extensions` in the left navigation.
3. Pick **Add to Chrome** or **Add to Firefox**.

## Install on Chrome or Firefox

### Chrome

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

### Firefox

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

## Merge Queue Controls

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.

## Stacks Panel

For repositories using [Stacks](/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](/stacks/reviewing#revision-history) timeline so you can see how each
commit evolved across pushes without leaving GitHub.
