ONE-TIME SETUP

Connect your Firefox to Social Publisher

Keep using your own Firefox Multi-Account Containers. The companion connects your browser to your Social Publisher dashboard.

Install the companion

Use Firefox desktop. Select the button below and approve Firefox's permission request. Firefox might first ask you to Allow the site, then to Add the extension.

Once Firefox confirms installation, return to Social Publisher and choose Try again. You won't need to repeat this every time.

Firefox blocked installation?

Some Firefox setups do not allow direct website installation. You can still install the same Mozilla-signed file once, without developer tools:

  1. Download the signed .xpi installer.
  2. In Firefox, open Menu → Add-ons and themes.
  3. Click the gear icon → Install Add-on From File.
  4. Select the downloaded file and confirm the installation.

Never change Firefox security settings. Only install the companion from your Social Publisher website. Firefox must stay available when publishing through containers.
