One Year Anniversary 🎊 (May 7, 2025)

We’re approaching the one-year anniversary of the launch of Lightning Autofill v12 (May 15, 2024), when we decided to switch to the freemium model with the update to MV3. The LAF team would like to take a moment to look back on this journey. When we first started, we could barely cover our operating expenses after living off our savings while working on version 12. It got pretty hairy on more than one occasion, with lots of negativity early on – a lot as a result of us shooting ourselves in the foot with critical bugs. There were bouts of second guessing ourselves. However, somehow we managed to overcome every challenge, push through every obstacle 💪. Fast-forward a year, and we’re happy to announce that today Lightning Autofill on MV3 has reached a level of financial and code stability where we have some breathing room again.

Looking back, we have absolutely no regrets walking away from lucrative offers to buy Lightning Autofill that would have resulted in an uncertain future for our loyal users. Since we are now cash flow positive with the freemium model, we would like to officially announce our Halving Pledge as a way of giving back to the community as well as growing our subscriber base.

⭐ Halving Pledge ⭐

We pledge to cut our subscription prices in half every time our number of subscribers doubles. Starting with v14 (see release notes below), you will see a progress bar in Settings / Subscription:

In order to make Lightning Autofill more affordable for you guys faster, we will implement these milestone goals:

The progress bar data is automatically retrieved from the Stripe API every hour. The starting subscriber count is the total number of subscribers at the end of May 1st, 2025. You can hover the mouse cursor over the progress bar to see the exact percentage at any given time.

Lightning Autofill v14.0.0 BETA released

We’ve made a ton of changes under the hood, mostly migrating Firefox to MV3 and rearchitecting for the future. Here are the changes that you can actually see:

Changelog:

⬇️ Install

Update on v14 (Apr 13, 2025)

We have officially started work on version 14! It will have some major changes, especially for Firefox users. Many users may not know that even though the Chrome/Edge version of Lightning Autofill has been on MV3 since v12, the Firefox version was still stuck on a clunky MV2/MV3 hybrid code base where we have legacy Firefox MV2 code living alongside MV3 code shared from the Chrome/Edge version, mainly because Mozilla’s implementation of MV3 was too different from Google’s implementation. As a consequence, this setup was prone to bugs and was a maintenance nightmare. Starting with Firefox v136, Mozilla’s implementation of MV3 has been further aligned with Google’s MV3 to the point where the Chrome/Edge and Firefox extensions can finally share the same MV3 code base, which will make maintenance a lot more streamlined.

Attention: Firefox users

BACK UP YOUR DATA.

What does this mean for Firefox users? While we make every effort to test as thoroughly as possible on Firefox, nothing is guaranteed. Hence, you should make a full backup of your data by going to Lightning Autofill Options / Sync and clicking on the Export button. For those who are on older versions of Firefox and don’t want to update to v136 or newer, we will keep the last MV2 version of Firefox (v13.15.2) around for a while to help with the transition.

Breaking changes

$() renamed to LAF$()

The initial release of version 14, v14.0.0, will mostly include architectural changes to prepare for exciting new features to come (e.g., macro recorder, AI autofill). One of the breaking changes will be to the way JavaScript rules are processed. Currently, your JavaScript rules don’t have access to global variables on the web page because they exist in a different “world”, which limits the rules’ power. Starting with v14, your JavaScript rules will be able to interact with global variables like jQuery’s $() since they will share the same world. While this is a big improvement, it means the special function $() to reference variables in your JavaScript rules will be renamed to LAF$() to avoid conflicts with pages that use the $ global.

Lightning Autofill v13.15.2 released (Apr 6, 2025)

This is a hotfix release to patch up some recent regressions.

Changelog:

Lightning Autofill v13.15.0 released (Apr 2, 2025)

This was originally just a hotfix release, but while we were at it, we added some quality-of-life improvements also.

Lightning Autofill v13.13.2 released (Mar 28, 2025)

Lightning Autofill v13.13.2 has been released to the main (stable) channel. Expect the update to roll out to Chrome, Edge, and Firefox within the coming days.

Changelog

v13.13.2

v13.13.0

v13.12.5

v13.9.3

v13.7.14

New Korean payment methods (Mar 22, 2025)

Good news for folks in Korea – we now support the following payment methods through Stripe Checkout:

Lightning Autofill BETA v13.13.2 released (Mar 19, 2025)

This update addresses two reported issues:

  1. In some cases, input elements that were inserted into the document dynamically after page load via AJAX were not getting autofilled. This has been fixed.
  2. If you have two profiles, each calling the other in a circular reference using the AUTOFILL action, the loop would break after one cycle and these two profiles would not call each other indefinitely as expected. This has been fixed.

⬇️ Install

Lightning Autofill BETA v13.13.0 released (Mar 17, 2025)

This is a small update that includes some optimizations to bi-directional cloud sync that didn’t make it into the previous release. We also improved the rule generation code to prevent potential duplicate profile or rule IDs when adding new profiles and rules.

⬇️ Install

Lightning Autofill BETA v13.12.5 released (Mar 12, 2025)

The main highlights in this release:

  1. Lightning Autofill’s internal CSS selector generator was rewritten to be up to 300x faster. We’re not kidding – check out the benchmarks. The previous version of our CSS selector generator was called getUniqueSelector() and the new version is genUniqueSelector7(). All the other functions are from third-party libraries, which either produced overly long CSS selectors or were too slow. You can see how much faster it is by generating rules on Google Forms with the “Parse labels” option disabled. CSS selectors are generated for the Name column as a fallback whenever fields have no unique attribute values. If a concise CSS selector is not found either, then an XPath is generated as a last resort.
  2. Fixed a number of cloud sync issues. For those who have “Bi-directional sync” enabled, the syncing should be a lot more reliable now.
  3. Updated the rules generator to work with the latest Microsoft Forms HTML code. Lightning Autofill should now be able to generate rules for Microsoft Forms regardless of whether you have the “Parse labels” option enabled. NOTE: The “Parse labels” option is required for Google Forms with shuffled questions.

Changelog:

⬇️ Install

Lightning Autofill BETA v13.9.3 released (Feb 27, 2025)

In addition to various bug fixes, we made two big enhancements to cloud sync in this update:

  1. Data now syncs to Google Sheets when you generate rules without having to open the Options page first.
  2. When you first start Edge or Firefox, you no longer have to go to the Options page to reconnect your Google account.

The video below illustrates this. In the video, we load Edge, and without opening the Options page to reconnect our Google account, we update an autofill rule using the infobar wizard (change value from “aaa” to “zzz”). This updated rule is then synced to Google Sheets.

https://screenrec.com/share/w0jd3QGmse

What’s not shown in the video is another improvement to cloud sync: when you have bi-directional sync enabled, Lightning Autofill automatically retrieves data from Google Sheets before generating new rules so that you minimize the risk of overwriting new rules that were added to Google Sheets from another PC or browser (a big quality-of-life improvement for cloud sync users who manage rules in Google Sheets from multiple devices).

If there are no reported bugs for a week, then this should be the last release before it gets pushed to the stable channel.

Microsoft Forms update

It appears Microsoft recently updated the HTML code of Microsoft Forms. From now on, if you want to properly autofill Likert multiple-choice questions such as the one below, you need to disable the “Parse labels” option when generating rules.

Shutting down for Lunar New Year 🎊 (Jan 19, 2025)

The Lunar New Year is the biggest festival of the year for us. The Lightning Autofill team will be shutting down from January 19 to February 2. Please do NOT send any alternative payments during this time as nobody will be around to process them.

There are two known bugs with BETA v13.7.10 that will be addressed when we return:

  1. The generated site filter for about:blank iframes is “blank”, which might result in unexpected behavior since it’s too generic. We will fix this to use the parent frame’s URL instead.
  2. There are some regression issues with generating rules for certain rich-text editors that rely on inline iframes. This is still under investigation, but we should be able to get it resolved after we return.

Skip BETA v13.7.9 and wait for v13.7.10 (Jan 15, 2025)

Please do NOT install BETA v13.7.9 because there was something wrong with that package that broke the autofill. Thank goodness it didn’t go out to the production channel or it would’ve been a disaster 😅. I will make another announcement here when BETA v13.7.10 is released. Apologies for the inconvenience!

Lightning Autofill BETA v13.7.9 released (Jan 14, 2025)

To prevent disruptions for people who use Lightning Autofill in mission critical applications, we have launched a new BETA channel to test new releases before they are published to the main production channel. This is similar to Chrome release channels, and we think it will help reduce headaches for you guys down the road. For those who want to try out the latest changes in Lightning Autofill before it’s officially released, or just to help test the extension, please install from the link below. The latest version will remain in the BETA channel for 1-2 weeks before moving to the production channel if no bugs are reported. You can have both beta and production versions installed at the same time.

Lightning Autofill BETA channel »

In this update, we fixed a lot of cloud sync issues, so this feature should be a lot more stable now. We also added support for forms that are dynamically created inside iframes using the about:blank hack, allowing Lightning Autofill to work its magic on more types of tricky forms. Last but not least, we added the “Reveal password” option to allow you to quickly reveal the password in password fields.

Changelog:

Lightning Autofill v13.3.0 released (Jan 2, 2025)

As promised, we changed the default matching to be case insensitive, so migrated autofill rules should work the same as in v12 now. For example, in v13.2.0, this rule would fail on the Practice Form because “Fullname” does not match name="fullname" since it’s case sensitive:

Type = Text
Name = "Fullname"
Value = Marty McFly

Starting in version 13.3.0, this rule would match like in v12.x.x and earlier since the matching is case insensitive. To force a case sensitive match, you will need to use regex (e.g., /Fullname/).

Changelog:

HAPPY NEW YEAR!! 🎉🎆 (Jan 1, 2025)

🥂 Wishing everyone a warm, safe, and joyous New Year 🥂

May your autofills & automations bring you to greater heights in 2025 🚀
