Latest version
Version 1.3.7
Released Jul 27, 2026 - 37.04 KBWorks with firefox 109.0 and later- Added an adjustable flash sensitivity slider.
- Sensitivity can be set from 1 to 5 flashes per second.
- The default remains 3 flashes per second.
- Lower values make detection react sooner, while higher values make it less sensitive.
- Flash-brightness settings can now be adjusted in 1% increments.
- Added a guided brightness calibration tool.
- The test starts with the page fully dimmed and gradually increases brightness.
- Users can stop the test as soon as the brightness becomes uncomfortable.
- CalmWeb saves a level 5 percentage points below the selected limit as a safety margin.
- The calibration does not deliberately generate flashing content.
- Added clear warnings explaining that the calibration is a comfort aid, not a medical test.
- Fixed an issue where brightness calibration could temporarily freeze.
- Fixed cases where the page could unexpectedly return to full brightness while the displayed percentage remained unchanged.
- Brightness transitions now run directly inside the webpage instead of depending on continuous popup messages.
- The calibration continues from the correct point after a temporary browser or interface delay.
- Removed the old preview timeout that could interrupt brightness changes.
- Closing or cancelling calibration now removes the temporary dimming layer correctly.
- Added a safety notice that opens when CalmWeb is installed.
- The notice explains that CalmWeb is intended to help but should not be relied on as the user’s only protection.
- It warns that features may occasionally respond late or stop working because of browser limitations, website changes, extension errors, high system load or other unexpected problems.
- Users are advised to continue using their normal safety measures and leave content that feels unsafe.
- The extension popup remains locked until the notice is acknowledged.
- The I understand button remains disabled for 10 seconds.
- A visible countdown shows when the button will become available.
- Closing the installation notice does not bypass the acknowledgement requirement.
- The acknowledgement is stored locally and is not requested again during normal browser restarts.
