Frequently Asked Questions
What is a user agent?
A user agent is a text string your browser sends to websites identifying itself: browser name, version, OS, and device type. Example: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36..."
Why do websites care about my user agent?
Websites use it to: serve mobile vs desktop versions, detect compatibility, block outdated browsers, check for malware/bots, and gather analytics. It's how sites know what you're using.
Can I change my user agent?
Yes. Browser DevTools (F12) allow temporarily changing it for testing. Browser extensions can spoof it. Changing it doesn't hide your identity (your IP does that); it just lies about browser/OS.
Is my user agent private?
No. Every request to a website includes it. It reveals your browser, OS, device type, and approximately your device model. It's like leaving a calling card at each site you visit.
What does "Mozilla" mean in user agents?
Historical quirk. All modern browsers claim to be "Mozilla" for compatibility (old sites checked for it). It doesn't mean you're using Mozilla Firefox. It's a legacy artifact.
Can user agent strings identify me personally?
No personal info is in the string itself, but combined with IP address, it helps track behavior across sites. Advertisers fingerprint you using user agent + other data.
Why is my user agent so long?
Historical compatibility. Browsers overclaim compatibility and include lots of data (OS versions, rendering engines, frameworks). Old websites relied on parsing these strings.
What is a bot user agent?
Search engine bots (Googlebot, Bingbot) have special user agents identifying them as crawlers. Websites use this to allow or block bots. Fake bots impersonate real ones for malicious crawling.
