User-Agent Switcher: Spoof and Mimic User-Agent Strings
The User-Agent Switcher for Chrome is a free add-on that allows you to quickly and easily switch between user-agent strings. If you're developing a website that needs to work on both mobile and desktop browsers, or if you're tired of being blocked by archaic sites that require Netscape 4, this extension is the answer. With User-Agent Switcher, you can also set up specific URLs that you want to spoof every time.
It's important to note that this extension does not provide improved privacy while browsing the internet, and some sites may still be able to detect that you're not using the browser you're pretending to be. Additionally, running this extension may have a performance impact on your browsing experience due to its need to intercept and modify the data communicated to the server. If you experience issues with sites after using a mobile user-agent, you may need to switch back to Chrome and clear your cookies for the sites to function normally again.
