What's new since 1.8.0
• Fixes lookups failing silently when Firefox has not granted access to the lookup service: the extension now detects it and shows a "Grant access" button (settings page, toolbar popup, info card) plus a "!" badge
• Settings page is now split into tabs (Lookup / General / Privacy & Support / About), with auto-save, switches and dark mode
• The toolbar popup shows the current keyboard shortcuts next to each switch
• Info cards always include a link that opens the website and searches the IP/domain for you (in your language)
• Failed lookups show the reason and a "Try again" button; temporary network errors are retried automatically
• Version info and version history in settings

What's new since 1.3.1
• Domain lookup: hover a domain for WHOIS and DNS records
• Keyboard shortcut lookup (Alt+Shift+L) — select an IP/domain or point at it, no hovering needed; hover and shortcut now have separate on/off switches
• Card display time setting (never / 3–60 seconds)
• "Look up this site" button in the toolbar popup (sent only when pressed), with CNAME / IP / name servers
• Reverse DNS (PTR) section with forward check on IP cards
• Copy buttons (whitespace removed), info cards inside small iframes, "too many lookups" notice
• Interface languages: English, 繁體中文, 简体中文, 日本語 — switchable in settings
• Version info and version history in settings
