v2.4.0 — Mobile support + API key validation
New
Firefox for Android fully supported — responsive layout fills the panel width
API key validation on → press — invalid keys show red error, nothing is saved
Fixed
Cookie bypass — credentials: omit on all NextDNS API calls; browser session cookies no longer silently auth garbage keys
Android DNS flush banner — replaced shell command with helpful mobile instructions + Reload button
Firefox desktop popup height — body grows with content, block list scrolls independently
Popup width — 440px on desktop with proper min-width; fluid on mobile
