The Easy Way: Install a Browser Extension
We recommend using the GoodTwitter extension—available for Google Chrome or Mozilla Firefox—for this. Install the extension, refresh Twitter, and you’re done.
This extension is open-source, so you can see what it does on GitHub. Whenever you access Twitter.com, it sends a user agent saying you’re using Internet Explorer 11. Twitter sends the old, classic web interface to users of this older browser.
Skip the Browser Extension: Change Your User Agent
If you’d rather do this without the GoodTwitter extension, all you have to do is change your browser’s user agent to Internet Explorer 11 while it’s accessing Twitter.com. There are many ways to do this. The main thing is you don’t want to change your browser’s user agent all the time, or you’ll get all sorts of ancient web pages intended for Internet Explorer 11 across the web.
For example, in Firefox, you can do this with an about:config preference—no browser extension required.
To do so, type about:config into Firefox’s address bar and press Enter. Click “I Accept the Risk” to bypass the warning. As long as you’re careful about what you modify in about:config and follow the instructions here, you’ll be fine.
Right-click on the list of settings and select New > String.
Name it general.useragent.override.twitter.com . Give it the value Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko . Click “OK,” and you’re done.
However, you will have to clear Twitter’s cookies and sign back in before your changes take effect. To do so, visit Twitter.com, click the site info icon to the left of the URL, and then click “Clear Cookies and Site Data.”
