When you're surfing online, your web browser acts as a user agent. From an application's point of view, it is used with one of several TCP/IP networking protocols, which enables the connection to the site you want to reach.
This lets web sites know what type of device, operating system, and browser you are using. However, if you wish to spoof your traffic and make it seem like it's coming from another device/browser, you can.
All popular browsers offer built-in user agent switchers, so it's easy to do and you don't need to install any extra extensions or third-party apps.
Chrome’s user agent switcher is part of its Developer Tools.
1. Open Chrome and click on the Menu button
2. Click on 'More Tools' and select 'Developer Tools'
3. Click the menu button next to 'Console' and select 'Network conditions'
4. Uncheck the 'Select automatically' option
5. Select a predefined user agent from the list
Note: This setting only works while you have Developer Tools open and only affects the current tab.
To rotate your user agent using Firefox, you'll need to access the about:config page.
1. Type about:config in the address bar and press Enter
2. This will pop up a warning, that you'll be changing standard browser settings. Click on 'I accept the risk!'
3. Type useragent in the filter box.
4. Right-click on the about:config page, click 'New' and select 'String'
5. Customize the string. Enter the name 'general.useragent.override'
6. Enter the user agent you'd prefer. If you're unsure what to enter, double-check with a reputable list such as this one.
Note: This setting will apply to every open tab until you disable your custom user agent. Even closing and reopening the browser won't set it back to default. To revert Firefox to its original user agent, right-click general.useragent.override and select 'Reset'.
This option is available in the browser's 'Develop' menu, which is normally hidden.
1. Click on the 'Safari' tab
2. Select 'Preferences'
3. Click the 'Advanced' tab
4. Enable 'Show Develop menu in menu bar'
5. From the 'Develop' tab select 'User Agent' and choose an option from the list
Note: This option only applies to the current tab. Other tabs you may open will still use the default user agent.
To switch the user agent you'll need to go to the developer tools.
1. Click on the settings menu and select 'F12 Developer Tools'
2. This will open a separate pane at the bottom. Click on the 'Emulation' tab and go to 'User agent string'
3. Select a user agent from the list or enter a custom one
Note: This option only applies to the current tab and lasts only while the 'Developer Tools' pane is open.
