← Knowledge BaseTestingView is built for browser-based TradingView use through the supported extension flow. Install links are browser-specific: Chrome and other Chromium browsers use the Chrome Web Store, Microsoft Edge uses the Edge Add-ons store, and Firefox uses [addons.mozilla.org](https://addons.mozilla.org/en-US/firefox/addon/testingview/). From testingview.com, use **Get extension** or open `/extension` for an automatic redirect.
