Connect your account and switch it on
Click the extension icon in the Firefox toolbar, paste the unique key from your dashboard, and flip the toggle. From then on, incoming buyer messages get answered for you.
Switching from Chrome?
Turn off or remove the Chrome extension before enabling the Firefox one. Two copies watching the same inbox will both reply — your buyers would get duplicate messages.
How it works
Watches your open inbox
While your Marketplace messages page is open in Firefox, the extension monitors for new buyer messages — nothing runs on our servers on your behalf.
Replies with your context
Answers use the business details, listing context, and tone you configure in your dashboard, so every reply sounds like you.
Updates itself
Firefox checks our update feed automatically, so you always run the latest version without reinstalling anything.
Updates are delivered automatically through our Firefox update feed.
