After resetting your user agent, you may need restart Firefox and clear your cookies and cache: Click the Library button on your toolbar. (If you don't see it there, click the menu button then click Library.)Click History and select Clear Recent History.; In the Time Range to clear: drop-down, select Everything.; Below the drop-down menu, select both Cookies and Cache. Open up Firefox browser. In the adderss bar, type the following: about:config; Right click on any empty space and select New- String, and set the preference name as general.useragent.override. In older version of Firefox, you can just search for general.useragent.extra.firefox.; Right click and select Modify or double click on it.; In the Enter string value dialog box, type in the user agent.

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.

We go into a lot more detail, and examine what makes up a UA, and how you can use user-agent parsing to your advantage, in our article User-Agent Parsing: How It Works And How Can It Be Used.

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.

iPhone User Agents

Below are examples of User Agent strings used by the most popular iPhone devices. As Apple do not pass much info through the User Agent, version numbers don't allow us differentiate between iPhone models.

However, with DeviceAtlas client-side, you can classify these user agents to return correct device model.

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.

Table of Contents

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

Note: If your user agent shows a previous Windows version, such as Windows NT 6.1 (Windows 7) instead of Windows NT 10.0 (Windows 10), make sure you are not running Firefox in Compatibility mode. You can open the Properties of the Firefox desktop shortcut from the right-click context menu. Check the 'Compatibility' tab and make sure that the compatibility mode option is not selected.

To reset your user agent:

  1. Type about:config in the address bar and press EnterReturn.
    A warning page may appear. Click to continue to the about:config page.
  2. Search for useragent by typing it into the Search field.
  3. Right-clickHold down the control key while you click on each of these preferences, if they exist, and select Reset from the context menu.
  1. Type about:config in the address bar and press EnterReturn.
    A warning page may appear. Click to continue to the about:config page.
  2. Search for useragent by typing it into the Search preference name field.
  3. Click the Reset or Delete button on each of these preferences, if they exist:
  • general.useragent.extra.firefox
  • general.useragent.extra.productName - where productName can be the name of some third party software (e.g. microsoftdotnet).
  • general.useragent.locale
  • general.useragent.override
  • general.useragent.security

See Configuration Editor for Firefox for more information about using the about:config page to reset or delete preferences.

User Agent Mozilla

Note: If the above solution doesn't resolve the problem, check whether you have the privacy.resistFingerprinting preference set to true and, if so, double-click on the preference to reset it to false. This setting can change the user agent and cause this type of issue. For more information, see Firefox's protection against fingerprinting.

After resetting your user agent, you may need restart Firefox and clear your cookies and cache:

  1. Click the Library button on your toolbar. (If you don't see it there, click the menu button then click Library.) Click and select .
  2. In the Time Range to clear: drop-down, select Everything.
  3. Below the drop-down menu, select both Cookies and Cache. Make sure other items you want to keep are not selected.
