Amazon CloudWatch Synthetics adds multi-browser support for application testing

Amazon CloudWatch Synthetics now enables customers to test and monitor web applications in Firefox, in addition to existing Chrome support. This enhancement helps customers ensure consistent functionality and performance across different browsers, making it easier to identify browser-specific issues before they impact end users. With this launch, you can run the same canary script across Chrome and Firefox when using Playwright-based canaries or Puppeteer-based canaries. CloudWatch Synthetics automatically collects browser-specific performance metrics, success rates, and visual monitoring results while maintaining an aggregate view of overall application health. This helps development and operations teams quickly identify and resolve browser compatibility issues that could affect application reliability. Multi-browser support is available in all [commercial AWS Regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/). To learn more about configuring multi-browser canaries, see the canary docs in the [Amazon CloudWatch Synthetics User Guide.](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch%5FSynthetics%5FCanaries.html)
