About Subtitle Masker
Extension Name: Subtitle Masker
Description:
A draggable and resizable subtitle-masking tool. Click the extension icon while watching a video to overlay a blur mask over the subtitles. The mask automatically follows the video into and out of fullscreen.
Key Features:
- Masks subtitles in video players to reduce distraction
- The mask can be freely dragged and resized by its corners/edges to precisely cover the subtitle area
- Mask position and size are remembered per website, so different sites keep their own layout
- Blur intensity is adjustable from the options page (a single setting shared across all sites), with a one-click reset for all saved positions/sizes
- The mask automatically follows the video into and out of fullscreen — no manual re-adjustment needed
- Helps you stay focused while learning a language and improves foreign-language listening comprehension
How to Use:
- Install and enable the extension.
- While watching a video, click the extension icon to show the mask, then drag or resize it to cover the subtitles.
- To adjust the blur strength, open the extension's options page and use the slider; click "Reset" to clear the saved position/size for all sites.
- Click the extension icon again, or double-click the mask, to quickly hide it.
