Version 3.6.1
Released Nov 26, 2025 - 109.92 KB
Works with firefox 109.0a1 and later, android 120.0 and later
Version 3.6.1 (Hotfix)

User Interface & Compatibility Fixes
* Android Compatibility: The "Add Global" container option is now automatically hidden on devices that do not support Containers (such as Firefox for Android) to prevent confusion.
* Popup Display Fixes: Resolved a display issue where lists of items inside sub-frames were not rendering correctly.
* Script Detection: Improved the accuracy of detecting and listing script domains within the popup menu.

Version 3.6.0 (Performance & Stability Update)

Improvements
* Instant Clearing: You can now properly set the data clearing delay to 0 seconds for immediate action (previously, this could default back to 30 seconds).
* Performance Boost: Significant "under-the-hood" optimizations to reduce memory usage and improve the speed of background processing.

Bug Fixes
* Container Settings: Fixed an issue where Container Blacklist/Whitelist modes were not saving correctly after restarting the browser.
* Icon Badge Accuracy: Fixed a timing issue that occasionally caused the counter badge on the extension icon to display incorrect numbers.
* Settings Synchronization: Resolved an issue where the Options page would falsely warn about "unsaved changes" when settings were updated from another tab.
* Stability: Added safeguards to prevent the Options page from crashing if settings take a moment to load.

Version 3.5.1
Released Nov 25, 2025 - 109.37 KB
Works with firefox 109.0a1 and later, android 120.0 and later
v3.5.1

Smarter Data Cleaning for Containers
We’ve completely overhauled how data is cleared when you use Multi-Account Containers. The extension now understands the difference between data specific to a container (like Cookies) and shared data (like Cache).
* Container Data: Cookies, LocalStorage, and IndexedDB now clear immediately when you close the last tab in a specific container.
* Global Data: Shared items like Cache and Service Workers will wait to clear until you have closed the website in all containers.
* Why this matters: This prevents accidental logouts or data loss in your other active tabs while ensuring your specific container is cleaned up instantly.

Performance Improvements
* Faster Options Page: We’ve optimized the settings engine, making the Options page load and save significantly faster (up to 50-100x faster for users with many rules).
* Reduced CPU Usage: The cleaning process is now more efficient, skipping unnecessary checks when closing tabs.

Bug Fixes & Stability
* IPv6 Support: Fixed an issue where IPv6 addresses (e.g., local development servers) were not being detected correctly.
* General Stability: Fixed several edge cases that could cause silent failures or “race conditions” when opening and closing tabs rapidly.
* Improved Logic: Added safeguards to ensure data is never cleared while a tab is still in the process of opening.
