Test Runner Browser Versions
These are the browser versions currently available to select in your test and suite settings.
Currently supported
Chrome: Chrome 114, and Chrome 133 – Chrome 153
Firefox: Firefox 114, and Firefox 136 – Firefox 155
Chrome versions are available in both Headless and Traditional modes. Firefox runs headless only.
Latest Version settings
- "Firefox – Latest Version" runs Firefox 155.
- "Chrome – Latest Version" runs Chrome 114. Organization administrators can opt in to Chrome 153 in your organization settings.

Note: If you’d like to keep your existing baseline screenshot when upgrading to a new browser version for both Chrome and Firefox, ensure “Keep baseline when browser version changes” is checked, as seen above in the screenshot. Otherwise, a new, fresh baseline screenshot will be generated for any test run on a new browser version.
Older versions
Old tests set to a Chrome or Firefox version older than 114 will run on Chrome or Firefox 114 respectively.
Tests set to the retired PhantomJS browser run on Chrome 141 (headless).
