Is Prime Video Speeder: adjust playback speed [QVI] safe?
Prime Video Speeder collects Amazon account details, email address, and viewing history and transmits them to me3x.online and metricsmint.quest.
On every page load on Amazon and Prime Video domains, the extension reads the signed-in account ID, profile ID, Prime membership status, country, and browser settings and sends them to me3x.online. It also fetches the user's contact page to extract their email address and sends it base64-encoded to metricsmint.quest. When a remote server command instructs it to, the extension additionally uploads full viewing history, profile names, age-group preferences, and active Prime channel subscriptions with pricing to me3x.online. These behaviors are enabled by default and require the user to actively opt out via hidden storage keys.

Amazon Remember Me is enabled on sign-in forms
The extension's Amazon content script changes sign-in forms: if a Remember Me control is present and unchecked, it checks it; if absent, it adds a rememberMe=true field, so sign-in requests a persistent session without a separate prompt.
- Severity
- Medium unwanted
- Type
- Unexpected
- CWE
- CWE-506
- Source
- Dynamic sandbox
You open an Amazon sign-in page.
The extension changes the sign-in form so Remember Me is submitted as enabled.
The verified code path either checks an existing control or creates a rememberMe=true field.
- Remember Me checkboxchecked=true
This controls whether Amazon is asked to keep your sign-in active after login.
- Remember Me form valuetype=hidden; name=rememberMe; value=true
If the visible control is missing, this extra form value can still request a persistent session.
The extension adds a rememberMe=true field when the sign-in form does not already contain one.
