I can but this shortcut is very convenient

Firefox is very customizable so I thought I can edit some settings in about:config to fix this

it already exists and it’s called Yacy, an open source decentralized search engine

You can add interested videos to playlist “Watch later” and it will available on all devices with your account

I remember how I had Firefox, which also used vertical tabs, hiding the address bar when there is no cursor on it, the minus is that because of this, the entire center of the sites will be shifted
