The User-Agent (UA) string is contained in the HTTP headers and is intended to identify devices requesting online content. The User-Agent tells the server what the visiting device is (among many other things) and this information can be used to determine what content to return. Of course this requires using a device detection solution which translates UAs into understandable software and hardware information.

User-Agent list for different device types

There are millions of User-Agent combinations given that UAs change with the software and hardware. For example, a Chrome browser on an iPhone 6 will introduce itself using a different UA than a Safari browser on the same phone.

Every device type, including phones, tablets, desktops, may come with its own UA that makes it possible to detect this device for any purpose. Interestingly bots and crawlers also come with their unique UAs.

Here is a list of example User-Agents for different device types that can be detected. If you'd like to learn more on these devices, just copy and paste the UAs to our User-Agent testing tool. You'll see all the properties of a detected device.

A user agent is a line of code that 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.

You can change Firefox's user agent to trick websites into thinking that you're using a different browser or operating system. Web developers might do this to see how their websites will appear on different systems and browsers. Sometimes, add-ons and other installations can change your user agent without your knowledge.

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.

To view your user agent, click the Firefox menu button , click Help and select Troubleshooting Information. This will open a page with the address about:support. The Application Basics section will include a User Agent entry. For example, the default user agent entry for Firefox 72 on Windows 10 (64-bit) would appear as:
_{Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0}
