Websites can read more than your IP, including your user agent, language, timezone, screen size, and device properties.

I built Spoof Me to let Firefox users switch these signals together as one browser identity.

It includes ready-made profiles, custom profiles, and a warning badge when a website accesses fingerprint-related properties.

It does not change your IP address or promise complete anonymity. The add-on does not collect browsing data and is MIT licensed.

I’d appreciate feedback on the profile consistency, permission explanations, and any fingerprint signals that should be added.

Firefox already includes fingerprinting protection, but I wanted more control over the browser profile that individual websites see.

So I built Spoof Me.

It lets you choose a ready-made browser identity or create your own, changing signals such as user agent, language, timezone, screen size, and device properties together.

It also displays a warning badge when a website accesses fingerprint-related properties.

It does not change your IP address or claim to make you anonymous.

I would appreciate honest feedback, especially about the available profiles and whether the permission explanations are clear.

I built Spoof Me, a free browser extension that lets you switch between consistent browser fingerprint profiles.

It can modify signals such as user agent, timezone, language, screen size, canvas, and device properties. You can use ready-made profiles or create your own.

It also shows when websites try to access fingerprint-related signals.

I would appreciate feedback on the interface, available profiles, and any signals that should be added.

I built a small Chrome extension called Spoof Me for inspecting and changing common browser fingerprinting signals.

The basic idea is that a VPN changes your IP, but your browser can still expose things like user agent, timezone, language, screen size, canvas, WebGL, and other values that can make sessions easier to link.

I’m not claiming this gives perfect anonymity. I built it more as a practical testing tool to see what the browser exposes and what happens when those values are changed.

I’d appreciate feedback from people who build Chrome extensions or understand browser privacy:

What fingerprinting signals are actually worth spoofing?

Which ones usually make the fingerprint more unique instead of less unique?

Are there any Chrome extension permission/security issues I should think about?
