Vuora by ゆろち

A productivity helper that bundles 12 categories of features into a single popup.

■ Features available on Firefox
🔹 YouTube Enhancements (35 sub-features)
Remove search-result noise, Shorts removal (5 sub-features), watch-page tidying, comment/live-chat hiding, grid column count, hiding "Most relevant" in Subscriptions, subscription channel expansion (subs feed → grid + lazy thumbnail), live-stream connection monitor, and more granular controls for YouTube's verbose UI.

🔹 X Cleaner (9 sub-features)
Hide the right pane (widening the timeline into it) / trends / who to follow / messages dock / promoted posts / Premium upsells / Grok / engagement counts, and open Home on the "Following" tab. Selectors are structural data-testid matches only, so they do not depend on the display language.

🔹 Amazon Subscribe & Save totals
On amazon.co.jp/auto-deliveries, retrieves missing prices from Amazon and shows unit price × quantity totals in the list. When delivery prices are missing, current prices or previous delivery unit prices are used to show a reference total. The billed amount may change and coupons are not included. No partial total is shown unless all items are available. Legacy monthly pages remain supported.

🔹 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 (12 sub-features)
Adds an optional video seek bar and image download buttons. Space toggles playback while the seek bar option is enabled.
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, wall-thump guard (bass cut), 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.

■ Save and load settings
The "07 Settings" tab brings together browser settings sync and JSON export/import. Save all feature settings, EQ, blocked channels, color history and selected tabs, and transfer them to another PC or between Chrome and Firefox. Sync on/off, destination accounts, authentication, caches and on-site overlay positions remain device-specific. Imported feature settings also sync when sync is on. The popup has a refreshed, calmer design in Japanese and English, with light and dark themes.

■ Privacy
Settings are stored in browser.storage.local; optional settings sync shares eligible settings through the browser's sync service. Browsing-assistance data is not sent for advertising, analytics, or telemetry. Contact details are sent to Kagayoi Support only when you submit the optional form; image retrieval, subscription channel thumbnails, the connection monitor, Gemini Notebook, and Amazon Subscribe & Save price retrieval use only the network requests required by the features you explicitly operate or enable. Amazon retrieval runs only while ON, using read-only requests with Amazon authentication cookies to the same https://www.amazon.co.jp origin. Amazon receives delivery, subscription, history, and order identifiers, product URLs, and your IP address. Orders and deliveries are not changed, and nothing is sent to the developer's server. Results stay only in page memory; turning the feature OFF or navigating away cancels requests and discards results. See docs/privacy-policy.en.md for details.

■ Requirements
Firefox 142 or later.
