Vuora

A productivity helper that bundles 11 categories of features into a single popup.

■ 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 0–300% amplification, auto distortion guard, night mode, mute, and a 10-band graphic equalizer with presets. The Firefox edition runs on a Firefox-only in-page audio pipeline (MediaElementSource): settings apply to all tabs automatically without opening the popup, and no tab-sharing banner appears. Limitation: it cannot work on DRM-protected video sites (Netflix, Prime Video, DAZN, Disney+, etc.) — those videos still play normally. Audio is processed inside the page; nothing is recorded, stored, or transmitted.

■ 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.
