@hugovborges No terminal, digita "sudo apt-get install chromium-codecs-ffmpeg-extra", sem as aspas; ou "sudo apt install chromium-codecs-ffmpeg-extra", também sem as aspas. Depois é só reiniciar o Opera.

I think Opera should have acrylic material in its interface, like Opera Neon does.

@fair9-0 Sidebar has a switch to hide/show her.

It's more beautiful and modern.

Sidebar panels for various websites. Like there is in Vivaldi web browser.

Sidebar social media extensions. Like Instagram, Tumblr, Youtube etc.

Speed dial gravitational effect. Like in Opera Neon.

Speed dial circular icons. Like in Opera Neon.

It's possible to allow several independent pop-out videos?
