Why these add-ons are different

They are local-first. Your tabs, screenshots, snippets and focus history stay in the browser unless you choose to save them elsewhere. There is no account and no sync server.

Free is a working tool, not a trial timer. The paid upgrade unlocks extra capacity or controls, and the licence is a one-time purchase on Gumroad.

Every add-on has a plain privacy policy. None of them reads page content for advertising, and none sells data.

Firefox add-on questions

Are the Firefox add-ons free?

Yes. Each add-on has a free version that works without a timer. The paid upgrade is optional and costs 5 USD once for that add-on.

Do I need a Wharfly account?

No. The add-ons work without an account. A licence key is checked with Gumroad when you activate it.

Does Wharfly track what I browse?

No page content, URLs, titles or search terms are sent. A paid upgrade sends the license key to Gumroad to check it.

Where do I install them?

Use the Firefox Add-ons links on each card. The current list is also available on the Wharfly developer page.
