Twitter.com was updated with a new interface of recent. It is now more of a web app as it now appears as the mobile version. If you don’t like the new interface you can get the classic Twitter back. Here’s how:
Install a Browser Extension
A recommendation you should consider is the GoodTwitter extension that is available for both Chrome and Firefox. Install the extension, refresh Twitter and that’s it.
The extension is open-source and you can observe its operations on GitHub. When you try to visit the website address, Twitter.com, the extension sends a user agent saying that you’re making use of Internet Explorer 11 and Twitter will then send the classic web interface to users of the old browser.
Change your User Agent
If you don’t want to use the first method, you can change your browser user agent to Internet Explorer 11 when you want to visit the website. There are a myriad of ways to get this done, but make sure you don’t make a habit of changing your browser agent always, else, a lot of older versions of the web page that is meant for Internet Explorer 11 will be sent to you.
In Firefox, you can change your user agent with an about:config preference without having to use an extension.
To do this, type about:config into the address bar in Mozilla Firefox and press Enter, then click “I accept the Risk” to avoid the warning. Be careful about what you change and follow the instructions in the about:config and you won’t have any problems.
Right-click on the list of settings then select New > String.
Change the name to general.useragent.override.twitter.com . Give it the value Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko . Finally, click “OK”.
