Features & Capabilities

Lightning Autofill is a powerful Chrome extension that streamlines form filling, automation, and text expansion to save time and reduce repetitive typing. It fills far more field types than the browser’s built-in autofill (text inputs, checkboxes, radios, selects, rich text editors, and more), supports smart targeting via CSS/XPath/regex, and can recover form data after crashes. Advanced features include macros/JavaScript rules for clicking and submitting, random data generation, hotkeys, profiles, and local import/export.

Choose from Free, Plus (unlimited executions + Google Sheets cloud sync), or Pro (Plus features + JavaScript rules, variables, and reCAPTCHA support). Lightning Autofill is privacy-focused — no tracking or analytics by default — but data stored locally is not encrypted, so avoid autofilling highly sensitive items unless using secure measures. Try Plus or Pro risk-free with a 3-day free trial.

User Reviews

User reviews largely praise the add-on for autofilling fields, especially with multiline textareas, and some positive remarks like “Nice Apps.” However, the dominant dislike centers on pricing and licensing changes: persistent monthly subscription fees, a move to freemium/Pro under MV3, and gating that disrupts usage. A few users report reliability issues or interruptions when updating or hitting limits. Overall, opinions split between perceived usefulness and frustration with monetization and update model.
Pros
  • Works with textarea (multi-line text)
  • Nice Apps
  • Core autofill functionality for filling form fields
Cons
  • Monthly subscription / recurring cost (5 € / $5 per month)
  • Shift to freemium model with Pro and MV3 migration (paywall after many years)
  • Pro upgrade prompts disrupt usage / licensing gating (update to Pro)
  • Occasional reliability issues and usage limits (e.g., daily limit)

Pay a subscription for a clunky UI.

Seriously wants you to pay about 5 € every month if used more than 10 times a day. Using Greasemonkey instead

Is Lightning Autofill Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Lightning Autofill requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Lightning Autofill is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
