Not too long ago, Pushbullet got all prettied up for Android 5.0. The app is a great example of a third-party developer coating their software with Material Design dust and spreading it out to users via an update (I'm pretty sure that's how all this stuff works). Now the team has given its browser extensions the same treatment.
The goal is for the Pushbullet experience to look largely the same regardless of where you access it, whether it's the site, the extension, or the Android app. This update introduces Pushbullet's softer shade of green, and it supplies a gentle case of the warm fuzzies all the way around. The new look has rolled out to Chrome, Firefox, and Opera users alike.
