 <time datetime=2025-09-14 class=text-body-secondary>Sunday, September 14, 2025</time></div><p>Over the past two years, Selenium has included <a href=https://www.selenium.dev/documentation/selenium_manager/>Selenium Manager</a>, a CLI tool (written in Rust) that provides <strong>automatic management of drivers and browsers</strong> across all official language bindings (Java, JavaScript, Python, .NET, and Ruby). Its purpose is to simplify the developer experience: if you create a driver object like this:</p><div class=highlight><pre tabindex=0 style=background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-java data-lang=java><span style=display:flex><span><span style=color:#000>WebDriver</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#000>driver</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#ce5c00;font-weight:700>=</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#204a87;font-weight:700>new</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#000>ChromeDriver</span><span style=color:#000;font-weight:700>();</span><span style=color:#f8f8f8;text-decoration:underline>
 </span></span></span></code></pre></div><p>Selenium Manager takes care of detecting whether Chrome is installed, downloading the required driver, and even provisioning a copy of <a href=https://googlechromelabs.github.io/chrome-for-testing/>Chrome for Testing (CfT)</a> if Chrome is not present on the system. This also works for Firefox and Edge, on Windows, Linux, and macOS.</p><p>Beyond driver and browser setup, Selenium Manager also implements <strong>telemetry</strong>. Once per day and user, it sends anonymous usage data to a <a href=https://plausible.io/manager.selenium.dev>public Plausible dashboard</a>. The purpose is to help project maintainers understand how Selenium is being used. While telemetry has generated some debate in the community, the dataset occasionally reveals interesting patterns.</p><h3 id=an-unexpected-browser-version>An Unexpected Browser Version</h3><p>When reviewing the telemetry recently, one statistic stood out. Most users (70.1% of the total users at the time of this writing) don&rsquo;t specify a browser version explicitly, which is expected. But surprisingly, <strong>28.8% of the total users — over 28 million unique clients — report running the exact version 127.0.6533.99 of Chrome</strong>. These numbers are growing daily, since if we filter the results to the last 28 days, we discover the number of users using this version is over 40% of the total.</p><p>Importantly, specific browser versions are only gathered by Selenium Manager when the user explicitly requests a given version with the Selenium API as follows (the example below is Java, but this can also be done with the rest of Selenium bindings). Alternatively, a browser version can be specified with an environment variable (<code>SE_BROWSER_VERSION=127.0.6533.99</code>). In any case (the Selenium API or the environment variable), users have explicitly selected this version.</p><div class=highlight><pre tabindex=0 style=background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-java data-lang=java><span style=display:flex><span><span style=color:#000>ChromeOptions</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#000>options</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#ce5c00;font-weight:700>=</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#204a87;font-weight:700>new</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#000>ChromeOptions</span><span style=color:#000;font-weight:700>();</span><span style=color:#f8f8f8;text-decoration:underline>
