Why Use the Extension?
Faster than any alternative
No need to copy URLs, switch tabs, or navigate to a testing tool. Two clicks and you're testing.
Real browsers, not emulators
Every session runs a full browser instance on a cloud server. You see exactly what real users see — including browser-specific quirks.
Test localhost and staging sites
With SSH tunnel support on paid plans, you can test local development servers directly through the extension.
5 browsers available
Chrome, Firefox, Edge, Brave, and Tor. Test across engines — Blink, Gecko, and more.
Frequently Asked Questions
The MyBrowser Chrome extension lets you instantly test any webpage in a different browser directly from your toolbar. Right-click any link or click the extension icon to open it in a cloud-hosted Chrome, Firefox, Edge, Brave, or Tor browser — without leaving your current browser.
Yes, the extension is free to install and use. Free users get 5-minute sessions (or 30 minutes with a free account). Paid plans unlock longer sessions and additional features like geo-browsing and file uploads.
The extension is built for Chromium-based browsers, so it works in Chrome, Edge, Brave, and other Chromium browsers. A Firefox add-on is planned for a future release.
DevTools device emulation only simulates screen sizes and user agents — it still uses your local browser engine. MyBrowser runs a real, full instance of the target browser on a remote server. You see exactly what a real user would see, including browser-specific rendering differences, font rendering, and JavaScript behavior.
Yes. The extension simply opens a URL in a cloud-hosted browser session. All browsing happens on our isolated servers in disposable Docker containers. No browsing data is stored after the session ends, and the container is permanently destroyed.
