Description
User-Agent switcher with import/export profiles and a selectable spoof depth (headers-only or full). Override your browser's User-Agent with named, reusable profiles — switch how sites identify your browser and device in a couple of clicks, without a heavyweight header editor. UA Intercept is single-purpose (User-Agent + matching Client Hints) and lets you choose how deep the spoof goes. FEATURES • Profiles — create, edit, duplicate, reorder, and delete named UA profiles; one active at a time. • Selectable spoof depth — "Headers only" changes just the wire User-Agent; "Full" also rewrites what page JavaScript sees (navigator.userAgent / navigator.userAgentData) and sets matching sec-ch-ua* Client Hints. • Preset picker — Windows/macOS/Android Chrome, macOS/iOS/iPadOS Safari, Linux Firefox, Googlebot, or a custom User-Agent. • Import & export — back up your profiles as JSON, or import your existing ModHeader profiles. • Per-profile URL filters, Incognito support, and a toolbar badge showing the active profile. • 20 languages (including Traditional Chinese, with RTL) and a keyboard-accessible UI. • Optional update check (off by default) via GitHub's public API. PRIVACY No ads, no tracking, no account, no data collection. Your profiles stay on your device. HONEST LIMITATION "Full" spoof defeats casual User-Agent sniffing, not a determined fingerprinter, and does not cover Web Workers. This is a developer/QA tool, not an anonymity tool.
