Fixed favicons not loading — popup CSP blocks external images, favicon fetching now routed through background script which converts responses to data URLs
Fixed favicons silently failing — two separate onMessage listeners meant the getFavicon handler was never reached, merged into a single listener
Fixed horizontal scrollbar flash when removing a domain — caused by translateX pushing the item outside the container, removed horizontal movement and added overflow-x hidden to the list
Fixed domain list flickering on remove — previously called renderList() after animation which rebuilt all DOM nodes and re-triggered entrance animations on every remaining item, now removes only the single node directly
Fixed Clean Now button growing when clicked — spinner was in the flex row pushing content wider, moved to position absolute with fixed button height so layout never shifts
Added real favicons for domain entries via background script proxy
Added animated progress bar during cleaning
Added ripple effect on buttons
Improved domain remove animation — two-phase fade then height collapse so items below slide up smoothly
