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.
A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".
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.
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.
To override the user agent string from Microsoft Edge DevTools: In the User agent section, disable the Select automatically checkbox.

The Send Feedback icon in Microsoft Edge DevTools The new Microsoft Edge web browser is based on Chromium, the same core that Google Chrome uses.
It may identify as Chromium because of that and that should give it the same level of compatibility with websites and applications as Google Chrome. One of the main motivations for doing so is Edge's improved support for media streaming sites like Netflix.
Edge may restrict exposure to one of the supported DRM plugins on select sites. It does so for CBS, Shudder, TV now, Bitcoin and Sling currently, and exposes only Google's Wide vine to these sites.
Microsoft has not published any article or information on Edge's user agent changing capabilities. Microsoft picks the classic Edge browser to unlock high quality streams on certain media streaming sites, Google Chrome when the user agent offers advantages, and the default user agent of the browser on the majority of sites out there.
When you load a web page such as groovyPost.com, a list of checks are performed to determine the platform (macOS, Windows, Linux), web browser (Microsoft Edge, Chrome or Safari for iOS) and the system type (x86 PC, Galaxy Tab, iPhone/iPad). You likely see the difference when you load our website in Microsoft Edge on a Windows 10 PC vs Chrome on an Android smartphone.
A feature of web browsers called the user agent string makes this happen. Select the Emulation tab then click in the User agent string list box.
Both Edge and Internet Explorer support a variety of modes, including Opera, Safari, Firefox, and Chrome. When selected, the page you are browsing will be refreshed in real time, letting you see how it behaves in that particular web browser.
Click in the Custom list box then choose the desired browser mode. Opera’s Developer Tools are based on Chrome, but accessing it is a bit easier.
Unlike Chrome, Opera, Edge, and IE, Firefox doesn’t have a user -friendly way to quickly switch the user agent string. If editing the configuration by hand makes you leery, I recommend you use a quick and easy add-on.
Choose the desktop web browser and operating system platform to view the desired website. But modifying the user agent string will let you download the ISO image directly if the page detects another platform such as Linux or macOS.
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 mapping the new Edge token to a browser name, Microsoft recommends using a different name than the one developer used for the legacy version of Microsoft Edge to avoid accidentally applying any legacy workarounds that are not applicable to Chromium -based browsers. 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. If you ever wanted to make your web traffic seem like it was coming from a different browser–say, to trick a site that claims it’s incompatible with yours–you can.
If you don’t see the console at the bottom, click the menu button in the top right corner of the Developer Tools pane–that’s the button just to the left of the “x”–and select “Show Console”. On the Network conditions tab, uncheck “Select automatically” next to User agent.
It only works while you have the Developer Tools pane open, and it only applies to the current tab. To create the preference, right-click on the about:config page, point to New, and select String.
This setting applies to every open tab and persists until you change it, even if you close and reopen Firefox. To revert Firefox to the default user agent, right-click the “general.user agent.override” preference and select Reset.
Microsoft Edge and Internet Explorer have user agent switchers in their developer tools, and they’re nearly identical. To open them, click the settings menu and select “F12 Developer Tools” or just press F12 on your keyboard.
The developer tools will open in a separate pane at the bottom of the window. You can find extensive lists of user agents on various websites, such as this one.
It only applies to the current tab, and only while the F12 Developer Tools pane is open. Chris has written for The New York Times, been interviewed as a technology expert on TV stations like Miami's NBC 6, and had his work covered by news outlets like the BBC.
Since 2011, Chris has written over 2,000 articles that have been read more than 500 million times---and that's just here at How-To Geek. However, until recently it was hard for me to switch completely due to no «offline» support for Google office suite: doc, spreadsheet and slides.
Fortunately, with the recent introduction of chrome extensions support it's now possible to put them offline with a few tricks! This is to be expected since functionality is experimental, so offering it to any browser alongside with extension will break things.
