The gap
A long reply, support ticket or application typed into a web form disappears when the tab closes, the browser crashes or the session expires, and Firefox does not bring it back.
Developer tools
Zapazka
A Firefox extension that keeps what you type in web forms and gives it back with one click, checks the text itself for card numbers, IBANs and keys, and shows for every field why it was kept or refused.

Get it on
The Lite edition is free and complete for what it does; the full edition adds more.
What it solves
What it is
Zapazka keeps the text as you type, in your own browser, offers it back the moment you return to the empty field, and proves what it refused instead of asking you to trust it.
How you use it
Never type the same long text twice.
A one-time, local form saver for Firefox users who write in web pages and want to see, not assume, that nothing sensitive is kept: forums, webmail, ticket systems, CMS editors and job applications.
Who it is for
Use it when
- A developer whose long bug report survives a crashed browser
- A support agent whose half-written ticket reply survives an expired session
- A job seeker whose cover letter in an application form survives a closed tab
Built for
- People who write long texts in web pages: developers, support teams, writers
- Anyone who has lost a form to a crash or a timeout
What is inside
Kept as you type
Text areas, rich editors such as webmail and forum editors, and one-line fields from 20 characters are kept half a second after you stop typing, and when you leave the field or the page. Only in your Firefox profile.
Back with one click
Come back to the empty field and a small chip offers the text with its length and age; Restore puts it in and the page sees it as typed. From the toolbar popup, Put back fills any field on the page with any kept version.
Never the secrets, and proof of it
Password fields, card and security code fields, one-time codes and fields named for tokens, PINs or secrets are skipped, as are hidden, disabled and read-only fields and private windows. Zapazka also checks the typed text: a valid card number, an IBAN, a private key, an API token or "password: ..." inside a harmless-looking message is refused, and digits kept before the number was complete are removed. The popup shows each field as kept or refused with the reason, and the ledger on the options page lists every refusal with field name, reason and time, never the text. Add your own never-keep words, exclude sites or pause saving.
Your rules
Choose how many days texts are kept, from how many characters one-line fields are kept and how many versions each field has. Search every kept text, export them as JSON or delete them all.

Questions
A Firefox extension that keeps what you type in web forms and offers it back after a crash, a closed tab or an expired session, with a toolbar popup and an options page. It comes as a zip with the extension file, its source folder, a README and pictures. It also checks the typed text, not only the field name: card numbers, IBANs, private keys and API tokens are refused, and the popup and the refusal ledger show each refusal with its reason.
Firefox 142 or newer on Windows, macOS or Linux, and permission to run on the sites you write in. Until Mozilla signs it, the release file installs in Firefox Developer Edition or Nightly, or as a temporary add-on.
Sync between computers, encryption with a password, Chrome or Safari versions, and fields in shadow DOM or canvas editors such as Google Docs. It was tested in a real headless Firefox 158, not yet on Firefox for Android or by hand over weeks. It recognizes well-known secret shapes only; for anything else use your own never-keep words or exclude the site.
Made by PN Scripts, a Sofia studio that builds games and tools, as a Manifest V3 WebExtension in plain JavaScript with no outside libraries and no network access. Created with AI assistance; the code was written for this product and checked by PN Scripts with 19 automated tests, Mozilla's addons-linter and a 15-step run in a real Firefox.
It is not on sale yet. When it is, this page will link to the store; PN Scripts does not take payment on this site.
