Twitter is rolling out real-time pop-up notifications to its desktop site over the coming weeks.
Users accessing the microblogging service on a PC or Mac computer will soon notice a notification box appear on the right-hand cover of their screen.
The feature will be used to alert users if someone has replied, favourited or retweeted one of their tweets.
Notifications will also appear for direct messages and new followers.
Within the boxes, users will be able to reply, favourite, retweet or follow without having to navigate away from the current page.
Account holders can also choose which notifications they receive on the settings page.
Twitter recently announced that its profile pages will undergo a radical overhaul with a layout similar to Facebook, including larger background images and more prominent profile pictures.
