Version 2.11.1
Released Jan 23, 2026 - 4.28 MB
Works with firefox 109.0 and later, android 120.0 and later
Removed unnecessary periodic URL check interval and dead code to reduce memory usage. Limited the one-click summarization cache size to prevent memory bloat. Added per-tab cache cleanup on tab close in the background script. Early return in main.js if the floating action button is disabled to avoid loading unnecessary modules.

Improved performance of the YouTube Quick Summary content script by throttling mouseover events, narrowing the MutationObserver scope, removing polling intervals, and caching style computations for container positioning. Also updated TOCMobile.svelte to use textContent instead of innerText for headings and to preserve existing heading IDs when generating anchor links.
