What Does Your User Agent Say About You?

Archive

A user agent is a computer program representing a person, for example, a browser in a Web context.

Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.

Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.

The user agent string can be accessed with JavaScript on the client side using the navigator.userAgent property.

A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

Platform identifiers change based on the operating system being used, and version numbers also increment as time passes. Mapping UA string tokens to a more human-readable browser name for use in code is a common pattern on the web today.

When Microsoft is notified about these types of issues, website owners are contacted and informed about the updated UA. In these cases, Microsoft uses a list of UA overrides in our Beta and Stable channels to maximize compatibility for users who access these sites.

You are able to view the list of UA overrides that are currently being applied by navigating to edge ://combat/user agent in the Beta and Stable channels of Microsoft Edge. You’ll also notice that the entire string ends with Edge /12.0, which Chrome does not.

There are ways to develop your website to progressively enhance itself based on the availability of features rather than by targeting specific browsers. Often, lazy developers will just sniff for the UA string and disable content on their website based on which browser they believe the viewer is using.

Internet Explorer 8 is a common point of frustration for developers, so they will frequently check if a user is using ANY version of IE, and disable features. The sergeant property has been aptly described as “an ever-growing pack of lies” by Patrick H. Lake in W3C discussions.

(“or rather, a balancing act of adding enough legacy keywords that won’t immediately have old UA-sniffing code falling over, while still trying to convey a little of actually useful and accurate information.”) For example, the Modernize library is a fantastic and simple way of detecting features.

Over the past year, we’ve seen some UA-sniffing sites that have been updated to detect Microsoft Edge … only to provide it with a legacy IE11 code path. In our experience Microsoft Edge runs best on the ‘WebKit’ code paths in these sites.

This decision likely based on the fact (from the perspective of Spartan/ Edge Developers), is that in the past, websites would look specifically for IE and notify users to use a different browser. Since Edge /Spartan was Microsoft's first attempt to modernize the Trident engine, and Edge /Spartan's purpose was to match the feature set of (Blink, Apple WebKit, and Gecko) at the time, the user agent simply advertising itself as being everything is one way to prevent Webpage designers from easily targeting Edge the same way they targeted IE.

Some pages will display incorrectly in IE while working perfectly fine on other browsers such as Chrome or Firefox. Neo win recently reported that Microsoft ’s new browser for Windows 10, Spartan, uses the Chrome UA string, “Mozilla/5.0 (Windows NT 10.0; WOW64) Apple WebKit/537.36 (HTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36 Edge /12.0.

You’ll also notice that the entire string ends with Edge /12.0, which Chrome does not. Often, web developers will UA sniffing for browser detection.

You can change the user agent of Microsoft Edge via Developer Tools menu. As mentioned earlier above, changing user agent in Microsoft Edge is extremely easy.

You can change it via Developer Tools menu which you can access by clicking the three-dot icon in the top-right corner of Microsoft Edge. As the Developer Tools window pops up, go to the Mode section and select the user agent you opt to via the drop-down menu on the Useragentstring option.

The landscape of mobile browsers is quite complex, with several major players (pre-installed in most cases) and a number of locally popular contenders. While all phones come with pre-installed browsers, both Google Play and Apple App Store offer a number of alternative browsers, some focusing on speed and lightness, others on saving bandwidth and blocking ads, and an ever-increasing amount claiming to increase privacy and reduce a users' mobile digital footprint.

A simple regex solution searching for keywords will struggle in terms of accuracy and detection speed. It offers a patented algorithm that detects and identifies all devices requesting online content through parsing UA strings based on a constantly updated, massive list of connected devices.

User agent is an HTTP request header string identifying browser, application, operating system which connects to the server. Not only browsers have user agent but also bots, search engines crawlers such as Google bot, Google AdSense etc.

Thanks for your feedback, it helps us improve the site. In reply to patrickmulhall's post on July 9, 2015, Internet Explorer user agent show Firefox 11 please change Internet Explorer because should it show the i.e. user agent because that is not part of the new browser.

In reply to Girish Pattabiraman's post on February 9, 2016, I would also like to know if the MS EdgeUserAgent change can be made to persist so that I don't have to go into developer and set the Sergeant every time. Thanks for your feedback, it helps us improve the site.

“Note that we recommend avoiding useragentstring detection if at all possible and sending Microsoft Edge the same content that you send other modern browsers. We will be iterating regularly on the Edge version number, so only look at the version when targeting specific bug fixes.

Something has added “MSI 9.0” to my UserAgentString for both Microsoft Edge, and Internet Explorer 11. It was working, then I installed a bunch of things, and not it is now.

Thanks for your feedback, it helps us improve the site. The iOS app is available today for a limited audience in Apple’s TestFlight system, and the Android app will be available shortly via Android’s Play Store Early Access.

A web platform is a complex piece of technology that in many respects duplicates aspects of an entire operating system in a single app. Part of our strategy with Edge HTML is to build an engine that, instead of replicating (and, in some senses, competing with) the underlying platform, integrates and works with it to deliver the best possible security, accessibility, battery life, interactivity, just pure raw performance on that platform.

We are proud of the work we’ve done with Edge HTML on Windows 10, all while driving the web forward with new capabilities and supporting interoperable standards. We are fully committed to continuing to do so into the future, across the full spectrum of Windows 10 platforms and form factors.

Mozilla/5.0 (Linux; Android 8.0; Pixel XL Build/OPP3.170518.006) Apple WebKit/537.36 (HTML, like Gecko) Chrome/58.0.3029.0 Mobile Safari/537.36 Edge /41.1.35.1 The app/OS identifier is chosen so that it does not contain the string Edge.” This is to avoid triggering any existing UA detection logic that might accidentally decide that these browsers are Microsoft Edge for Windows 10, resulting in a desktop site or something equally confusing.

Stay tuned to this blog (or follow us on Twitter) for more updates on Microsoft Edge, and be sure to try out the preview apps for yourself and let us know what you think. The new Microsoft Edge running on Chromium isn’t yet here officially, but a leaked build allows us to try out the browser in anticipation of its highly-anticipated release.

Using the browser on a daily basis isn’t obviously recommended as experimental builds like this can’t by any means become your main driver. For many users, switching to a different user agent and thus emulating another browser is a method to bypass certain website restrictions that concern a specific app.

The best example is Skype for Web, which doesn’t work in Firefox anymore, so Mozilla users need to switch to another user agent to connect to the service. In other words, switching to the Chromium-powered browser shouldn’t cause compatibility issues and still let your users connect to internal apps.

For those unfamiliar with this screen, it’s specifically supposed to provide developers with advanced tools that let them analyze code and website performance. Changing the user agent is actually considered a developer option that helps webmasters check their pages against potential compatibility issues with different browsers.

By default, Microsoft Edge is configured to Select automatically the user agent, so you need to uncheck this option to be able to choose a custom setting.
