YouTube Blocker + Tools — v3.10.15

Ad blocking
• Stronger network blocking (ads, tracking, and ad-related googlevideo segments when marked with oad=).
• On Firefox, ad-related JSON is now stripped from YouTube / Innertube API responses in the background (webRequest filterResponseData), so it still works when page CSP blocks injected scripts.
• Wider stats/URL filtering and improved in-page skip / seek behaviour when ads appear.

Panel & settings
• Panel split into “YouTube video” (playback, player, captions) and “YouTube Tools” (links, downloads, AI). Optional order and “start collapsed” in Settings.
• New quick actions: Play/Pause, jump to start, 0.75× speed, copy channel link.

Downloads
• Reworked download helpers: Cobalt (prefilled), noTube, fewer dead third-party buttons; improved yt-dlp copy command.

Reliability
• Floating button creation retries until the page is ready; less “nothing shows” on slow loads.
• Lighter DOM observers to reduce “unresponsive script” warnings while keeping ad skip.

Reminder: third-party download sites are outside Mozilla/YouTube; use at your own risk. Optional AI uses your own API key (see Options).

3.9.0

• Smoother YouTube UI: reduced heavy page scanning so search and typing stay responsive.
• More reliable tools: better video detection, improved buttons for like/dislike, subscribe, watch later, next, theater/mini mode, and chapters (works better with YouTube’s updated layout, including shadow DOM).
• Shorts & embeds: download shortcuts now resolve video IDs from Shorts and embed URLs, not only ?v= links.
• Optional AI assistant: summarize the current video or ask questions using your own OpenAI-compatible API key (configure from the extension popup → AI & API settings). No data is sent to the add-on author; requests go only to the API URL you choose.
• Bug fixes and stability improvements throughout the on-page tools panel.
