Frame Color per Site от Patrik Dudits

This browser extension dynamically changes the window frame color based on the active tab's URL, using user-configurable regex rules.

Features

• Configure multiple regex-to-color rules via the options page
• Rules are prioritized by order in the list (topmost wins)
• Enable/disable, edit, delete, and reorder rules instantly
• Theme color updates automatically when tabs or URLs change
• Restores default theme when no rule matches
