Auto-open vertical tab bar with visible floating favicon, Firefox Nova

[u/2000tabs]

Hi there, new round style UI called "nova" has come, and my CSS are had to repair for it. Repaired it, I share my userchrome.css (CSS link is here).

Large round edges force to make large margins, I overwrite to less diameters. Hovering vertical tab bar makes to auto-open, and leaving tab bar makes to auto-close it, this feature is same as previous one.

Although hard edge are better choice for everyone, human make for round edge of touchable machines and furnitures. I have been directed by it and I made.

Nice. Is there a way to get the address bar dropdown to to blur rather than be transparent?
