Introducing Firefox and Edge Support in Cypress 4.0

February 6, 2020

By The Cypress Team

Today, we're excited to release the highly-anticipated support for Firefox and the new Microsoft Edge browsers in Cypress 4.0. Adding the capability to run Cypress tests in Firefox has been one of the most frequently requested features by the community. So our team has been working hard to provide this feature with the same great developer experience users have come to enjoy and expect from Cypress.

With the power of testing in multiple browsers, comes the responsibility of implementing the right CI strategy to achieve an optimal balance of confidence, performance, and cost. To guide these crucial decisions, we're launching a new Cross Browser Testing Guide with various recommendations to help you implement the right CI strategy for your project and team.

Cypress 4.0 marks a significant milestone in the development of Cypress and sets the stage for an exciting pipeline of capabilities that will continue to elevate the testing experience for everyone.
