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".

And yes, the Browser data is here to stay and if you cannot cope with the extra size this causes please kindly download a different extension and don't down-vote. Note: Because Firefox 57 will drop support legacy add-ons, and I don't had any time to migrate it to Extensions yet, this project is in maintain mode, bug fix only, no new feature.

An user agent tells websites what type of browser and operating system you're using. This information helps the web server deliver content that's compatible with your browser.

If websites tell you that your browser is outdated or incompatible even though Firefox is up to date, an incorrect user agent may be the cause. This article explains how to fix problems with your Firefox user agent so that websites work properly.

You can change Firefox's user agent to trick websites into thinking that you're using a different browser or operating system. Websites may not display correctly or may show a message that your browser is outdated or incompatible, based on the detected user agent.

It's important to switch Firefox back to the default user agent so that websites work properly. The Application Basics section will show your current Firefox version and will include a Sergeant entry.

If you can't resolve the problem this way, follow the steps below to reset the default user agent. Type about:config in the address bar and press Enter Return.

Right-click Hold down the control key while you click on each of these preferences, if they exist, and select from the context menu. Type about:config in the address bar and press Enter Return.

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 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. It only applies to the current tab, and only while the F12 Developer Tools pane is open.

Rv: gecko version indicates the release version of Gecko (such as 17.0 “). 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/”.
