Install & Enable

StackPrism targets Chromium-based browsers (Chrome, Edge, Brave, Opera, Vivaldi, Arc, etc.) and requires Manifest V3 support.

Install from an extension store

• Chrome Web Store
• Edge Add-ons
• Firefox Add-ons

If the browser cannot be identified automatically, choose the matching store.

Option 1: Download the crx from a Release

1. Open GitHub Releases
2. Pick the latest version and download stackprism-v{version}.crx
3. Navigate to chrome://extensions/ (Edge: edge://extensions/), then enable Developer mode in the top-right corner
4. Drag the downloaded .crx file onto the extensions page
5. Confirm by clicking "Add extension" in the dialog

TIP

Chrome sometimes blocks drag-to-install for .crx files ("Apps, extensions, and user scripts cannot be added from this website"). If that happens, use Option 2 instead.

Option 2: Download the zip from a Release and load unpacked

1. Open GitHub Releases and download stackprism-v{version}.zip
2. Extract it to a stable directory (do not delete it — the extension depends on this directory at runtime)
3. Open chrome://extensions/ and enable Developer mode
4. Click "Load unpacked"
5. Select the directory you just extracted

Option 3: Build from source

Suitable for developers or users who want to track the latest main branch.

git clone https://github.com/setube/stackprism.git
cd stackprism
bun install
bun run build

The build output lands in dist/. Load the dist/ directory in chrome://extensions/ with Developer mode enabled.

After modifying source files, re-run bun run build, then click the refresh button on the extension card in the extensions page to load the new version.

Enabling and Permissions

On first install the extension requests the following permissions:

Permission	Purpose
tabs	Read the current tab's URL and title
activeTab	Inject detection scripts into the active page
scripting	Inject page-detector / page-source-search into the page's MAIN world
storage	Persist settings, cache detection results, and theme preference
webRequest	Intercept response headers to collect server / x-powered-by, etc.
<all_urls>	Run on all http(s) pages

Detection does not rely on any external API. Rule files are bundled locally with the extension, and detection results stay within browser memory and extension storage.

Uninstalling

Go to chrome://extensions/, find StackPrism, and click Remove. Settings and cached results are cleared along with it.
