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".

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. This allows you to request web pages intended for different browsers–or even different devices, like smartphones and tablets.
Click the menu button to the right of the “Console” tab at the bottom of the Developer Tools pane and select “Network Conditions” 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. You can find extensive lists of user agents on various websites, such as this one.
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 InternetExplorer 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. It only applies to the current tab, and only while the F12 Developer Tools pane is open.

Have you tried Microsoft Edge as the User Agent ? Try 'Other” at the bottom of the pop-up, enter the user agent string and “OK”.
I have searched the Web and find all sorts for Chrome etc but I cannot find a string to paste for IE of any version to run on Safari 13 I couldn't find Safari 13 specific IE user agent string either.
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 InternetExplorer version for Mac in 16 years. There is no sergeant String that would Identify a current InternetExplorer version on a Mac.
This will work for the agent string: Mozilla/4.0 (compatible; MSI 8.0; Windows NT 5.1; Trident/4.0) Unfortunately, you have to do this step each time you want to use the in question website.
Mozilla/4.0 (compatible; MSI 8.0; Windows NT 5.1; Trident/4.0) 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.
The Chrome (or Chromium/Blink-based engines) user agent string is similar to Firefox’s. For compatibility, it adds strings like HTML, like Gecko and Safari.
The Opera browser is also based on the Blink engine, which is why it almost looks the same, but adds “Or/
One workaround is to use the Sergeant String Utility referenced in Microsoft KB Article 923196. You could also directly modify the registry of the machine that you are on to always report IE6, however remember that there is an administrative overhead associated with this.
The data in the user agent string help the website to deliver the content in a format that suits your browser. Even though depending on user agents alone is no longer enough to optimize a website, they are still an important source of information.
Along with the user agent identification, the browser sends information about the device and the network that the user is on, like the IP address. The same is true for email clients and other programs that display website content.
For the breakdown we will concentrate on user agents that can be expected to be web browsers operated by humans. For these browsers the format of the user agent string is: Mozilla/ () () Since Opera, who were the last to adapt to this standard, also started using the Mozilla user agent string, every popular browser uses this and will start the user agent string with Mozilla and the version number.
Some browser extensions are noted in the user agent string if they need certain content to be rendered in a specific way. Of course sites with malicious intentions can use this information to deliver specific exploits that have a bigger chance of working on your system.
