Snap for Firefox Autor: rset

Snapchat Web shows "Browser not supported" in Firefox. This add-on fixes that by making Firefox look like Chrome to snapchat.com, and only to snapchat.com. Every other site sees your normal Firefox.

How to use
1. Click the toolbar icon and switch it On.
2. Open (or reload) web.snapchat.com.
3. A small toast confirms spoofing is active. The badge shows "ON".

What it does
- Rewrites the User-Agent and adds Sec-CH-UA client-hint headers on *.snapchat.com requests
- Spoofs navigator.userAgent / userAgentData on snapchat.com pages
- Automatically does a cache-bypassing reload if a stale "Browser not supported" page appears

Privacy
No data is collected or sent anywhere. The only thing stored is your on/off setting, locally.
