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
