User reviews
Users appreciate Lightning Autofill for saving time with its fast, easy, and reliable form autofill capabilities. However, many express frustration with the restrictive free version limit of 10 fills per day, occasional failures to save or autofill data, and a cumbersome user interface that complicates usage. Some also dislike recent updates, including requirements to log in with a Google account and changes that reduced functionality. Overall, while it is a valuable tool, its limitations and interface issues detract from the user experience.
Pros
- Helps save time and effort by quickly autofilling forms.
- Easy to use and reliable when it works properly.
- Allows creating and capturing template data for reuse.
- Fast and efficient compared to other autofill extensions.
- Good for improving productivity and convenience.
Cons
- Free version limits to 10 autofill executions per day, which many users find insufficient.
- The extension sometimes does not save credit card or profile info properly, causing autofill failures.
- UI and workflow are clunky and complicated; autofill execution requires multiple steps instead of being seamless.
- Requires Google account login, causing privacy or convenience concerns for some users.
- Recent updates (such as MV3 and usage limits) have negatively impacted functionality and usability.

Adarsha Secondary Boya, 2025-04-21I set up all the necessary fields, tested it once, filled it out once, and two days later, when I tried to use the plugin again, it told me I had exceeded the limit and had to buy the paid version. I had barely used it — maybe three times at most. I believe it’s a scam that doesn’t even provide the promised limit and pushes you to pay after you’ve already set everything up. I’m not against paid versions at all, but I didn’t even get what was promised in the free version.
