Open pages anonymously in one click!

Do you want to use VPN for specific websites only? Do you want to switch VPN in one click? Want to open a specific website anonymously? Website or URL is not opening? Not a problem. Anonymous Button solves it! This extension is for you! How it works? - Enter the URL you want. - Click "Anonymous" button in the browser panel! - Proxy VPN os ON! Just click again to turn it OFF! Browse and surf anonymously only where and when you want! Many people surf the web under the illusion that their actions are private and anonymous. Unfortunately, this is not the way it is. Every time you visit a website, you leave a calling card that reveals where you are coming from, what kind of computer you use, and other details. And some keep logs of all your visits forever, so that they can catch you! This service allows you to surf the web without revealing any personal information. It is fast, it is easy, and it is free! Be aware! Chrome incognito mode is collecting some of your data! We do not collect any of your data! To make it work, Anonymous Button uses best and free and fresh 3rd party proxies and VPN services.

2	Data Exfiltration	critical	files/background.js (line 1134)	The background worker exposes a generic 'fetch' RPC that performs an arbitrary HTTP request (any URL, method, headers, body) on behalf of the sandbox script and returns the raw response body. Combined with the chrome_…	4.0.0.1
3	Network Interception	critical	files/background.js (line 564)	The extension fetches lists of SOCKS5/HTTPS proxy servers from hardcoded remote endpoints, including a plaintext HTTP IP (188.166.142.39) and a CloudFront URL. All user browser traffic for selected domains is then rou…	4.0.0.1
4	Privilege Escalation	critical	files/background.js (line 1060)	The background service worker accepts arbitrary 'chrome_api' messages whose 'api_chain' array names any chrome.* method, which is then invoked with caller-supplied parameters. This is a generic chrome-API-RPC bridge t…	4.0.0.1
5	Remote Code Loading	critical	files/provider.js (line 166)	On every page load, the sandbox fetches a remote JSON file from 20162019.xyz and stores its contents as 'additional_sources' in chrome.storage. The background script later loads these URLs and treats their responses a…	4.0.0.1

7	Credential Theft	high	files/background.js (line 665)	The extension auto-supplies username/password credentials (delivered with the remote proxy list) to chrome.webRequest.onAuthRequired for any proxy host. Because the proxy list is fetched from remote, attacker-controll…	4.0.0.1

9	Tracking	high	files/background.js (line 900)	The extension writes a cookie on the suspicious third-party domain 20162019.xyz whenever a proxy error fires, and registers a declarativeNetRequest rule that strips the Referer header from any request to that same dom…	4.0.0.1
