A productivity helper that bundles 10 categories of features into a single popup (Volume Booster is Chrome-only).

■ Features available on Firefox
🔹 YouTube Cleaner (32 sub-features)
Remove search-result noise, Shorts removal (5 sub-features), watch-page tidying, comment/live-chat hiding, grid column count, subscription channel expansion (subs feed → grid + lazy thumbnail), live-stream connection monitor, and more granular controls for YouTube's verbose UI.

🔹 Amazon Subscribe & Save totals
On amazon.co.jp/auto-deliveries, computes per-month delivery totals and inserts them inline.

🔹 Amazon jump-to-ranking button
The bestseller-rank links in a product's detail section appear in different positions on every page and are hard to find, so this consolidates a "Go to this product's ranking" button at the top of the product info. Clicking it navigates (same tab) to the most specific subcategory ranking. Pure DOM manipulation, zero external transmission.

🔹 Amazon seller / shipper badge
Extracts the seller and shipper from the product page's hidden divs (#merchantInfoFeature_feature_div / #fulfillerInfoFeature_feature_div) and shows them as a "📦 Sold: XXX / Ships: YYY" badge at the top of the product info (right next to the jump-to-ranking button). Amazon-fulfilled and marketplace listings are visually distinguished (Amazon-fulfilled = green badge / marketplace = orange warning badge), making it easy to spot suspicious marketplace listings at a glance. The detection uses Amazon's own isInternal flag (embedded JSON in the <script> inside #merchantInfoFeature_feature_div) as the primary signal, with the seller name as a fallback. Pure DOM manipulation, zero external transmission.

🔹 Instagram Cleaner (11 sub-features)
Hides Reels / Explore / Stories / Threads / like counts / videos / comments / Notes / message counters, and similar verbose UI. Uses only semantic selectors (aria-label / role / data-pagelet); no dependency on obfuscated class names.

🔹 TikTok Cleaner (3 sub-features)
Hide comments / hide "Suggested accounts" / image download button.

🔹 Video Gamma
Global slider applies gamma correction to <video> elements (custom SVG <feComponentTransfer type="gamma"> implementation).

🔹 Remove video black bars
Removes the letterbox/pillarbox black bars on ultrawide screens by Zoom (aspect-preserving crop) or Stretch (expand only the deficient axis) to fill the screen. The video's aspect ratio is auto-detected; setting is shared across all tabs.

🔹 Loupe
Mouse-following circular magnifier. 3-step zoom / variable lens size. Uses tabs.captureVisibleTab so videos / iframes / canvases can also be magnified.

🔹 Color Picker (popup tab)
EyeDropper API based. HEX / RGB / HSL formats with up to 20 history entries stored in browser.storage.local only (no external transmission).

🔹 Volume Booster (Chrome edition only)
The Volume Booster captures tab audio via the chrome.tabCapture API, which Firefox MV3 does not support, so the Volume Booster is unavailable on the Firefox edition (the popup's audio section is hidden automatically). On Chrome / Edge it works on all sites (including EME-protected video such as Netflix / Prime Video) with 0–300% amplification, auto distortion guard, night mode, mute, and a 10-band graphic equalizer with presets (open the popup to operate it).

■ Privacy
Fully local execution; zero external network calls. Only browser.storage.local is used (no sync / no cloud). See docs/privacy-policy.md for details.

■ Requirements
Firefox 142 or later.
