PiP & Volume Helper by Ody Ninos

What it does
This adds a simple popup to your toolbar for controlling videos:

Pop a video into a small floating window that stays on top of other windows (Picture-in-Picture), even on sites that try to block it
Play, pause, skip forward/back, mute, and adjust volume
Works on ertflix.gr out of the box, including its "Start Over" and "Tune to Live" buttons
Want it to work on another site too? Just type in the website's name and approve the permission — you're always asked first

Your privacy
This extension doesn't collect or send any of your data anywhere. Everything it remembers (like your saved buttons) stays only on your own device.
