A lifetime license for one browser. It removes the three hour wait, unlocks unlimited sign ups, and includes every future update. The license key arrives by e mail right after the payment.
A real run against the built in test page. The account is created, verified, and logged in. You click once.
Every field is filled in: first name, last name, e mail, confirmation, password, date of birth, gender. Fields marked in green were filled in by the extension.

Open a page with a sign up form, click the extension icon, and press Register automatically. Everything else happens on its own:
| Step | What happens |
|---|---|
| 1 | Creates a temporary e mail address and a password |
| 2 | Fills the form: names, e mail, confirmation, password, country, gender, date of birth |
| 3 | Ticks the required checkboxes, including consent and terms |
| 4 | Submits the form |
| 5 | Waits for the verification e mail |
| 6 | Enters the code or opens the link |
| 7 | Logs in |
The account is saved to the vault. The next time you visit the same site, Log in is all you need.
- Form filling handles ordinary fields, custom
<select>elements, hand built listboxes, and code boxes - Shadow DOM support reaches fields even on sites that build them as web
components, such as
<w-textfield>, where plain HTML cannot get in - Verification reads the code from the e mail and enters it, whether the page uses a single field or six small boxes
- Seven languages: Swedish, English, Turkish, Arabic, Spanish, German, French. Arabic is laid out right to left
- Account vault stored locally in the browser, with a limit of 10, 50, or 199
- Export to CSV, PDF, or an encrypted backup
- Test page included, which walks through the whole flow without any outside service
The extension loads straight from the free-build folder. Nothing to build, no
npm required.
- Open
chrome://extensions - Turn on Developer mode at the top right
- Click Load unpacked
- Choose the
free-buildfolder
That folder is a complete Chrome MV3 extension. Pick it directly.
Firefox supports MV3, but the chrome.* namespace differs in places. Always
test on the browser you intend to ship to. Review manifest.json if you repack
it into an .xpi.
- Open a page with a sign up form
- Click the extension icon
- Press Register automatically
- Follow the progress in the log
After the wait the button locks and shows the time remaining. It unlocks by itself when the time is up, so there is nothing to reload.
Already have an account? Open the same page again and press Log in.
Want to try it first? Click 🧪 in the icon row at the bottom of the popup. That opens a built in test page which runs the entire flow with a real temporary e mail address.
Click ⚙️ in the icon row at the bottom of the popup. The page is dark and has three parts.
Language changes the interface. The popup updates immediately, with no need to close and reopen it.
Account vault holds every account you created, with export and delete.
- Keep newest sets the limit to 10, 50, or 199. The oldest account is deleted automatically once the limit is reached.
- Show saved accounts used to live in the popup and now lives here.
Advanced is collapsed. It contains the e mail provider and the RapidAPI key. If you leave it closed you never have to think about it.
The vault shows website, e mail, username, verification state, and password (hidden until you click). Export to CSV, PDF, or an encrypted backup.
Seven languages, changed under ⚙️ → Language:
| 🇬🇧 English | 🇸🇪 Svenska | 🇹🇷 Türkçe | 🇸🇦 العربية |
| 🇪🇸 Español | 🇩🇪 Deutsch | 🇫🇷 Français |
When you change the language it applies everywhere at once, including in a popup that is already open.
| Provider | Requirement |
|---|---|
| mail.tm (default) | Free, works immediately, no API key |
| temp mail (temp mail dot org) | Needs a free RapidAPI key |
Set under ⚙️ → Advanced. If no key is given, mail.tm is used automatically.
Note that both providers have their own limits on how fast accounts can be created. That is controlled by them, not by the extension.
Everything sits in the same place, ⚙️ → Account vault.
| Format | Contains | Encrypted |
|---|---|---|
| CSV | Website, e mail, username, created, status | No |
| The same details in a clean document | No | |
| .enc | Everything, including passwords and provider data | Yes, with a master password |
CSV downloads in a single click. PDF opens the browser print dialog, where you choose Save as PDF.
About passwords: CSV and PDF leave passwords out by default. Tick Include passwords if you want them included. The encrypted backup always contains everything, but it needs a master password both on export and on import.
CSV and PDF are not encrypted. The file lands in your Documents folder and
can be opened by anyone. Use .enc when you need to move accounts safely.
Read this before you start.
Every website is different. The extension finds fields using heuristics, so a site with an unusual flow, heavy bot protection, or its own login logic may refuse the registration or fill the form only partly. No technique works everywhere, and that does not change here.
CAPTCHAs are not solved. Some sites use proof of work as a barrier against bots. The extension ticks the box and lets the site do its own work, but it does not build a solver.
E mail only. The extension creates e mail addresses, not phone numbers. Sites that require an SMS code will not work.
It depends on the e mail provider. If mail.tm or the other provider rate limits you, or a message is not delivered, the run fails.
"Verified" is not a guarantee. The status means the site accepted the code you were sent. If a site rejects the account later, that is outside the control of the extension.
Always test on a site you actually care about before running several.
