Twitter recently introduced their bubbly “Edge” design makeover. As with any other design shifts on this planet, there are unhappy people on the Twitterland too. Here is a Chrome extension that lets you get the old Twitter design back.
As the name suggests, this is a debubbler. If the new design has already reached you, simply install this extension and reload your Twitter tab. You should get the old design back.
I am not sure how long this extension will work. That depends on how it rolls back the new design. If this is a CSS trick, there isn’t much to worry. However, if the extension is somehow accessing the old design from Twitter’s servers, it might stop working in the future.
