Riah Extensions

Direct answer

Riah Extensions is a public set of small browser extensions from Riah Studio for Chrome, Edge, Brave, and Firefox. Each extension does one job (autoplay guard, paste restore, YouTube controls, and similar), uses minimal permissions, and ships without telemetry or remote config. Limitations: not every extension ships on every browser when the browser already covers that job natively.

Small, readable browser extensions from Riah Studio. Each extension is scoped to one job, uses minimal permissions, and avoids telemetry, remote code, and remote configuration.

Publishable Extensions

Chrome, Edge and Brave are all Chromium and take the byte-identical package, so there is one Chromium build and one Firefox build — not four. Each store still gets its own zip under release/.

Two extensions ship to some browsers and not others

An extension is only worth installing where the browser does not already do the job. Two of the set are therefore deliberately partial, expressed by which manifests they ship (manifest.chrome.json / manifest.firefox.json) — the build and the static audit both enforce it.

Extension	Chrome / Edge	Brave	Firefox
Riah Cookie Quiet	ships — no native consent-notice blocking	not needed; Shields does it	not needed; Firefox's own banner blocker is one toggle in Settings → Privacy & Security
Riah Tab Sleeper	not needed; Chrome Memory Saver and Edge Sleeping Tabs	not needed; Memory Saver	ships — Firefox unloads only under memory pressure, with no idle timer
Riah Volume Boost	ships	ships	not possible; Firefox has no tabCapture or offscreen API

Brave takes the Chromium package minus Cookie Quiet; its exact daily set lives in Brave Migration/brave-migration.json.

Retired 2026-07-29 — the browser now does these itself

Deleted once every target browser shipped the same behavior natively. Rebuilding them would only add a second thing to maintain and trust.

Retired	Replaced by, everywhere
site-zoom	Native per-site zoom
zoom-baseline	The browser's own default zoom preference
page-translator	Native page translation
selection-translator	Native translation, including selected text

Their source is preserved under public-export/riah-extensions/extension-source/ if any of that ever regresses.

Quick Start

npm test
npm run build
npm run package:public

Build output is generated under extension-source/dist/. Store-ready ZIP files are generated under release/.

For a clean public GitHub seed, run:

npm run export:public

That writes public-export/riah-extensions/ with only public source, tests, docs, brand assets, and release scripts. Use that export as the public repo source instead of publishing this full local workspace.

Local Brave Check

Run Start All Riah Extensions in Brave.bat --check to rebuild the Chromium packages and verify the current load-unpacked set without opening Brave.

Double-click Start All Riah Extensions in Brave.bat to open the current Chromium build in a dedicated disposable Brave profile for manual testing.
