FLUF Connect Firefox Extension
The official FLUF Connect add-on for Firefox — crosslist, edit and sync your marketplace listings from one dashboard, without sharing your passwords.
- What it is: The official FLUF Connect add-on for Mozilla Firefox, listed on Firefox Add-ons (addons.mozilla.org)
- Why you need it: A few marketplaces connect through your own browser to keep your account safe — the extension handles that quietly in the background
- What you get: Crosslisting, edits, price changes, delisting and inventory sync — all driven from one dashboard
- Privacy: FLUF never sees or stores your marketplace passwords. You sign in to each marketplace as normal in Firefox.
- Cost: The extension is free. A FLUF Connect plan is required to use it — see plans
- Works on: Firefox on Windows, Mac and Linux (desktop only)
What the FLUF Firefox Add-on Does
The FLUF Connect Firefox add-on links Firefox to your FLUF Connect dashboard. Once it is installed, you can crosslist products, sync inventory, change prices and delist items across the marketplaces you sell on, all from one dashboard at fluf.io/connect.
There is nothing to operate day-to-day. The add-on sits in the Firefox toolbar and works in the background while you list, pack and ship.
- Crosslist an item from FLUF (or from a connected store like Shopify) to several marketplaces in one click
- Edit listings — price, description, photos — once in FLUF, and the change reaches every marketplace
- Delist items in bulk or one by one without logging in to each marketplace
- Inventory sync — when an item sells on one marketplace, FLUF removes it from the others so you don’t sell it twice
- Auto-relist older items to keep them fresh in marketplace feeds
How to Install on Firefox (3 Steps)
- Open the FLUF listing on Firefox Add-ons and click Add to Firefox, then Add in the prompt.
- Sign in to FLUF Connect at fluf.io/connect in Firefox. The extension detects your account on its own.
- Connect your marketplaces from the Channels page. For a few marketplaces you’ll be asked to log in in a Firefox tab — that’s all the setup there is.
Tip: if the FLUF icon is not on your toolbar, click the puzzle-piece Extensions button, then the gear next to FLUF Connect and choose Pin to Toolbar.
Firefox may also ask you to allow the add-on to access marketplace sites. Choose Allow so FLUF can work on the marketplaces you connect.
Install the FLUF Firefox Add-on
Free to install. Works with your existing FLUF Connect account.
Updating and Removing the Add-on
Firefox updates add-ons automatically. To check straight away, open about:addons, click the gear icon and choose Check for Updates. Updating never disconnects your marketplaces.
To remove it, right-click the FLUF icon and choose Remove Extension, or remove it from about:addons. Your FLUF Connect account, listings and history are not affected.
Privacy & Account Safety
- FLUF never sees your marketplace passwords. You log in to each marketplace in Firefox, the same way you always have.
- No central credential store to be breached. Because passwords aren’t stored on our servers, there’s nothing for an attacker to steal.
- You can disconnect any time — remove the extension or a marketplace connection from the dashboard. There’s no lock-in.
The extension only acts on the marketplaces you connect and on fluf.io. It doesn’t read or change your banking, email or any other sites — Firefox shows the full permission list before you install.
