AutoFillExt

Auto-fill forms with CSS Selector and XPath. Data stays local; license checks send no passwords or rules.

AutoFillExt fills web forms using CSS Selector and XPath locators, taking the repetition out of logins, sign-ups, captchas and other routine typing. Autofill data stays in your local browser storage; nothing is uploaded. ■ What it does • Element targeting — new locators use CSS Selector or XPath and cover the vast majority of web forms; legacy text locators keep working. • Auto-click — a locator can either fill a field or click a button, so a form can be submitted right after it is filled. • Multiple value sets — keep several sets of values per rule and switch between work and personal accounts from the popup. • URL matching — exact, regular-expression and glob matching cover subdomains, multiple login paths and URLs with parameters. • Import and export — export rules as JSON via the clipboard or a file, including the current format, the V1 layout and the early Base64 format, for backup and migration. • OCR captcha recognition — built-in local ddddocr inference; Pro adds PaddleOCR (PP-OCRv6). • Dark mode — follows the system theme in both the popup and the rule management panel. ■ Free and Pro Free covers up to 10 rules, with up to 3 locators, 3 URL patterns and 2 value sets per rule. Pro removes those limits and adds PaddleOCR. Pro is activated with a License Key through "Upgrade / enter License Key" in the popup. ■ Data and privacy • Usernames, passwords, rules, value sets, OCR images and page content are stored only in your local browser storage and are never uploaded. • License checks require the network and send only the License Key or signed license metadata, a device hash, the extension version and a nonce. • If the network is unavailable, basic autofill keeps working and Pro enters a grace period. • Locally stored data is not encrypted; avoid untrusted devices and export a backup regularly. Permissions (activeTab, storage, scripting, clipboardRead, clipboardWrite, tabs) are used only to read the current page, inject the rule management panel, save settings and access the clipboard.
