User reviews
Pros
- Effectively bypasses X-Frame-Options header allowing iframe embedding where normally restricted.
- Essential for certain functionalities like using ReCaptcha or enabling features in other extensions (e.g., Infinite Scroll).
- Open Source and considered a must-have by some users for enhanced browsing capabilities.
- No security or source code concerns mentioned, users see it as safe and reliable.
- Simple and does exactly what it promises without unnecessary complexity.
Cons
- Does not allow specifying particular sites to enable the bypass, raising potential security concerns.
- No longer sufficient for all use cases as modern web protections and scripts may still prevent certain content from loading properly.
- Fails to work in some scenarios, such as embedding Google.com, returning 'SAMEORIGIN' errors.
- Web security defenses like content security policies still interfere, limiting the extension's effectiveness.
- Users experience broken page previews or incomplete functionality due to other failed requests or scripts.

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.
Ignore X-Frame-Options Header requires some sensitive permissions that could impact your browser and data security. 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 Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on
Firefox Browser Add-ons, the amount of time the Firefox add-on has been
around, and other signals about the
Firefox add-on. 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 Firefox add-on.
Ignore X-Frame-Options Header has earned a fairly good reputation and likely can be trusted.
