WebDriver is a remote control interface that enables introspection and control of user agents. As such it can help developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the W3C and consists of two separate specifications: WebDriver classic (HTTP) and the new WebDriver BiDi (Bi-Directional).This newsletter gives an overview of the work we’ve done as part of the Firefox 142 release cycle.
Contributions
Firefox is an open source project, and we are always happy to receive external code contributions to our WebDriver implementation. We want to give special thanks to everyone who filed issues, bugs and submitted patches.
In Firefox 142, Sabina (sabina.zaripova) renamed Proxy capability class to ProxyConfiguration to avoid confusion with JavaScript Proxy.
Also, biyul.dev reverted a workaround for asyncOpenTime=0 in WebDriver BiDi and removed support for localize_entity from the localization module.
WebDriver code is written in JavaScript, Python, and Rust so any web developer can contribute! Read how to setup the work environment and check the list of mentored issues for Marionette, or the list of mentored JavaScript bugs for WebDriver BiDi.

Updated: the session.end command to resume the blocked requests
The session.end command was updated to resume all requests which were blocked by network interceptions.
Improved: support for setting proxy with browser.createUserContext command
Added support for host patterns like .mozilla.org in noProxy property and fixed a bug when setting a HTTP proxy wouldn’t allow navigating to HTTPS URLs.
Bug fixes
browsingContext.createcommand will not fail anymore after abrowsingContext.printcommand was interrupted by closing a tab with thebrowsingContext.closecommand.
Marionette
Updated: the WebDriver:AddCookie command to throw an error for sameSite=none and secure=false attributes
From now on, the WebDriver:AddCookie command will throw an error when a target cookie has sameSite=none and secure=false attributes.
