What's
New

ONEDAY license plan — new ONEDAY plan (Full Access – 1 Day) added alongside Trial, Monthly, 6-Month and Annual plans

Trial session counter — Trial plan now limits usage to 8 sessions of 15 minutes each; remaining sessions shown live as Trial — X/8 sessions left

Trial time lock — time inputs locked to 0h 15min max for Trial users; enforced on both input and change events in real time

License restore from sync — licenseKey, expiresAt and licensePlan automatically restored from chrome.storage.sync if local storage is empty after reinstall

deviceId synced to cloud — device ID stored in both chrome.storage.sync and local; sync checked first on load so ID survives reinstallation on the same Chrome profile

updateLicenseIndicator made async — now awaits chrome.storage calls to correctly read Trial session count before rendering the indicator

Trial sub-label updated — shows X/8 sessions left · 15 min each · max 2 images · 1 prompt instead of generic restriction text

Plan label mapping expanded — ONEDAY and HALF aliases added to plan label lookup used in activation toast and license indicator

Activation writes to sync — after successful activation, licenseKey, licenseValid and expiresAt now also persisted to chrome.storage.sync

Fixed Trial time inputs not enforcing limits — totalHours and totalMinutes now have dedicated handlers that clamp values to 0h / 15min for Trial users

Fixed deviceId regenerating on reinstall — now reads from chrome.storage.sync first before falling back to local, preventing unnecessary device ID changes

Warning banner — orange dismissable banner at the top of the popup reminding users to keep the Higgsfield.ai tab open and visible during generation

Report a bug link — footer email replaced with a Report a bug link pointing to higgflow.com/support.html

deviceId persisted to sync — device ID now stored in chrome.storage.sync in addition to local, surviving extension reinstallation on the same Chrome profile

License restore on reinstall — licenseKey, expiresAt and licensePlan automatically restored from chrome.storage.sync if local storage is empty

Fixed missing <script src="popup.js"> tag — truncated HTML caused JavaScript to not load, breaking license validation and all UI interactions

Fixed page scrolling down during generation — removed btn.scrollIntoView() in content.js that was auto-scrolling to the Generate button on every click

PRO license device reset — server allows deviceId update for PRO licenses max once per 24 hours, enabling reinstallation without losing the license. TRIAL licenses remain strictly device-locked.

Trial upgrade modal — clicking restricted features in Trial now opens a full modal window instead of a plain alert, with an Upgrade to PRO button

No-license banner — red banner appears at the top when no license is detected, with a direct Activate ↓ button that scrolls and focuses the license input

Trial banner — orange banner shown immediately after activating a Trial license, listing all restrictions clearly

Activation toast — success toast appears after license activation showing plan name and days remaining

Instant Trial mode — trial restrictions (orange banner, locked reference card, locked prompts) now apply immediately after activation without needing to restart the plugin

Spinner support — Trial image count limit now triggers correctly when using the ▲▼ spinner arrows, not only when typing

Add prompt button — button is no longer disabled in Trial mode; click now correctly opens the upgrade modal instead of doing nothing

Reference images card — card is no longer blurred when there is no license; blur lock only applies in Trial mode

Banner auto-hide — no-license and trial banners disappear immediately after successful activation without needing to close and reopen the popup

Fixed duplicate HTML rendering — popup was rendering twice causing a visual double-plugin appearance

Fixed "Enter your license key" banner persisting after license activation — old activationBanner element removed

Fixed currentLicensePlan not being set after activation — plan is now stored both in chrome.storage and in-memory immediately

Full UI redesign — new dark theme with Bebas Neue headlines, Familjen Grotesk UI labels, and DM Sans body font matching the Higgflow landing page aesthetic

HIGGFLOW logo centered in header, PRO badge removed for cleaner look

Section labels in lime — Generation, Time Limit, Reference Images, Prompts, License labels now use the brand lime #D1FE17 color

Transparent Start / Stop buttons — semi-transparent with colored border and text instead of solid fill

Reference images card switches appearance — grey/neutral when toggle is OFF, lime-bordered when ON

Removed Inactive status pill from top-right header

Removed ⛔ emoji from Inactive status bar

Fixed Cloudflare email encoding in footer — replaced with plain [email protected]

Trial license plan — added 24h trial with restrictions: max 2 images per round, 1 prompt only, reference images disabled

License re-verification on Start — license is checked against the server every time the user clicks Start, not only on activation

UI lock / unlock — all inputs are disabled when no valid license is present; unlockUI() re-enables everything after successful activation

Unlimited mode check — warns user before starting if Higgsfield's Unlimited toggle is OFF, to avoid burning credits

Server-side plan enforcement — verifiedPlan is returned by the API and used to limit image count and prompt count in content.js, preventing client-side bypass

Device ID binding — license keys are bound to a deviceId generated per installation using crypto.randomUUID()

Trial image snapshot — reference images sent to content script as a frozen snapshot at start time, preventing runtime injection of additional images

Reference image rotation — improved stability of rotation loop; restarts correctly when image list changes during an active session

IndexedDB sync — syncReferenceImagesFromSession() runs every main loop tick to detect image additions/removals in real time

Auto-stop cleanup — reference images cleared from IndexedDB and GUI automatically when generation ends due to time limit
