What Does Your User Agent Say About You?


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".

Making statements based on opinion; back them up with references or personal experience. Thanks to the new flags page in Internet Explorer 11, it is now very easy to change the user agent string.

You can experiment with it using the latest publicly available Windows 10 build at this moment, which is 9879. To change the Sergeant string in Internet Explorer 11, you need to open the Flags page mentioned above.

Type the text below in the IE address bar and press Enter on the keyboard: Now Internet Explorer 11 tells websites that it is Firefox running on Linux.

By Sergey Lukashenko on January 2, 2015, last updated on March 22, 2018, in Internet Explorer. Sergey Lukashenko is a software developer from Russia who started Winner back in 2011.

On this blog, Sergey is writing about everything connected to Microsoft, Windows and popular software. I have encountered some sites that claim false incompatibility with Internet Explorer 11.

Some sites, such as YouTube and Yahoo Mail, display an annoying warning that IE is not supported and I should consider another browser, however they do work fine without any noticeable compatibility issue! Other sites, such as Vodafone Greece, are even worse by denying to load at all unless I open them in another browser such as Firefox.

Other sites, such as Vodafone Greece, are even worse by denying to load at all unless I open them in another browser such as Firefox. I want to use Internet Explorer 11 instead, so I tried to open the Developer settings and change the user agent in Firefox or Chrome, but apparently I did not do that correctly, all the affected sites still detect I run IE 11.

User agent changes successfully but cannot trick Vodafone or YouTube. The thing is, Apple introduced its own proprietary browser known as Safari back in 2003 and Microsoft decided to end its development for Mac shortly after that.

Though using a Virtual Machine to install Internet Explorer on Mac is not an easy fête, it is available for anyone who feels it is the most practical technique. To get started, you will have to download VirtualBox and Windows 10 ISO File.

Under the “Installation Method” menu, click on “Create a new custom virtual machine”. Secondly, Virtual Machines will use a lot of your Mac memory resources which will compromise its performance.

This hidden menu includes a wide range of tools and features which can be used by any web developer. Two of them will come in handy if you are looking to use Internet Explorer on Mac or view non-cooperating sites.

Show Develop menu in Safariing you've done that, you will have the freedom to access Safari Developer tools with which you can empty caches, inspect websites and most importantly simulate other sites and in this case, Internet Explorer. Sergeant with Together webpage will then automatically refresh and be displayed in such a way that it would appear on Internet Explorer.

I couldn't find Safari 13 specific IE user agent string either. If Apple don't provide one, it is going to be tough to get IE user agent string working.

Do you have clone backup with previous version of Safari installed? There was a IE extension that used to be free on chrome as well and now they want to charge u for it.

I usually use the developer tab but my computer auto updated itself to 13.0.3 and not IE is gone ... There has not been an Internet Explorer version for Mac in 16 years.

There is no sergeant String that would Identify a current Internet Explorer version on a Mac. If you just want to trick the website into thinking you are using Internet Explorer, then any current version of Internet Explorer you would be using would have to be on Windows, so those strings should work.

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. Modify the user agent string sent by Internet Explorer by editing the Windows registry.

Since this tweak involves editing the Windows registry it is strongly recommended that a backup is made before making changes. Go to File menu export, navigate to a location, give filename and click.

Navigate to the following location HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\ Sergeant \Post Platform Right-click on the right pane and create a new String Value. If you want to remove certain values which have been added to the user agent string by the software you installed navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ Sergeant \Post Platform This location might not always exist but if its there you can go there to find some String Values.
