You can now instantly launch a Chrome browser as old as version 35 on our website and use it with your mouse and keyboard. Or use it in your Selenium IDE/Selenium Builder/Webdriver test to automatically test your website. We've added Chrome versions 35 - 45 for all Mac (Yosemite/Mavericks), Linux and Windows (XP, 7, 8, 10) platforms. ## Chrome and Firefox beta/dev versions We're also providing access to the latest beta and development versions of both Firefox and Chrome on all platforms. These versions are automatically updated on our side to follow the Chrome/Mozilla release cycle, so you're always testing the most recent beta/aurora and dev/canary candidates. Ready to get started? Pick the browsers you want to test on from our [+1500 list of browsers](https://testingbot.com/support/web-automate/browsers).
