If you use any browser, it is likely that you have seen the User-Agent Switcher.

Many websites ask your browser and operating system to identify you so they know which content is best for you to view. In the past, this was not possible to do on mobile devices.

Now, with User Agent Switcher, you can easily switch between user-agent strings to easily browse the web without seeing your real user agent, and spoof websites to easily browse the web as if you were using your favorite browser.

Also, if you want to test different websites and browsers, you can set specific URLs that you want to spoof, and your user agent will be replaced with the ones you specify.

Once you set up the user-agent switcher, you can simply install a new browser, restart the user-agent switcher, and it will switch back to the original browser. This way, you can easily switch back and forth between user agents without changing your default browser.
