No Nonsense Njuškalo by No Nonsense

On Njuškalo the same listings pop back to the top every day because sellers renew them. This extension remembers what you have already seen and gets it out of your way.

• A listing is marked as seen when you open it (in this tab or a new one) or press ✕ on its card.
• Seen listings disappear from every list page. A floating counter opens the list of hidden ads with search, categories and an "Unhide" button.
• When a hidden listing changes its price it comes back with a note: old → new price, percentage, and when you first saw it.
• When everything on a page is already seen, the extension can look ahead through the next pages of the same list and jump to the first one with something new (can be turned off in the popup).
• "Show hidden listings" for a quick peek, "Forget all seen listings" to start over.
• Optional sync between your devices: create a key on one device and enter it on the other. Records are encrypted in the browser before they are sent, so our server cannot read which listings you viewed, nor who you are. No account, no e-mail. Settings travel along.
• Hide with one click: ✕ on the card. Optionally automatic, for every listing you open; the first ✕ offers it, and the popup turns it on or off. Look-ahead to the next page is on from the start and can be turned off right where it happens.

Privacy: without sync nothing leaves your browser. With sync, only encrypted records the server cannot read are stored. No accounts, no analytics, no remote code. Runs only on njuskalo.hr.
