User reviews

Users appreciate the extension's usefulness for modifying HTTP headers and its simplicity. It supports URL filtering and is free compared to alternatives. However, many report it fails to modify headers in POST requests and sometimes stops working unpredictably. The UI and instructions lack clarity, causing confusion. Some browsers, like Brave, have compatibility issues. Users also note it does not effectively modify existing headers, limiting its functionality.

Pros

Useful for adding or modifying HTTP headers, especially for testing and debugging purposes.
Allows specific domain or URL filtering for header modifications.
Simple and easy to use once set up, with faster performance compared to some similar extensions.
Works well on Firefox, providing consistent functionality there.
Free to use compared to some alternatives.

Cons

Does not consistently work with POST requests; header modification is mostly limited to GET requests.
Inconsistent and unreliable behavior; extension sometimes stops applying headers at random intervals.
Limited support or failure on certain browsers like Brave, with some features not functioning after updates.
Poor or confusing user interface with inadequate instructions, making configuration difficult.
Does not modify existing HTTP header items effectively, limiting usefulness.

Doesn't work for POST request, but it says for all requests. Waste of time

Thanks you for this plugin: I added a custom authorization header in my browser to login without going to the login page to enter email and password

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Modify Header Value (HTTP Headers) requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.
