Features & Capabilities

Image Block X is a lightweight Firefox extension designed to give users control over image loading in their browser. With a simple toggle button, you can easily disable images to save data on limited connections or to browse faster when your internet speed is slow. Clicking the button again re-enables image loading for a richer browsing experience.

This extension is a modern rewrite of the popular Image Block tool, built as a web extension for better compatibility and performance. It offers a hassle-free way to manage images without navigating complex settings, making data saving and faster browsing just one click away.

User Reviews

Image Block X is valued for effectively blocking images and reducing clutter, saving data, and being simple and fast to use. However, users report inconsistent blocking across browser sessions, compatibility issues with newer Firefox versions like 119, poor icon visibility in dark mode, and occasional blocking problems in web apps such as Google Drive. Despite these issues, it remains a helpful tool for managing web visuals and data consumption.

Pros

Effectively blocks images and reduces unnecessary visual clutter on web pages.
Simple, fast, and easy to use interface with convenient toggle icon.
Helps save data usage by preventing images from loading.
Works well with multiple Firefox versions and platforms.
Appreciated for its usefulness in managing web content display.

Cons

Does not always persist settings across Firefox sessions; users must re-toggle the icon.
Incompatibility or malfunctions reported in certain Firefox versions (e.g., Firefox 119, Firefox 99).
Icon visibility issues, especially in Firefox dark mode (icon hard to see).
Blocks images in some web apps like Google Drive, causing connection warnings or functionality issues.
Does not block all images consistently on certain websites.

Recent reviews

Of course, and mirroring the total lack of thought beyond the absolute surface level of 90% of browser extensions, does NOT either allow blocking of images BEFORE they load (you have to load the website, click the icon's extension and refresh; every single time) OR the ability to do this for all websites in advance, instead being both per-website only with zero option for permanency of application. So, you know, if you actually want the obvious use case of avoiding seeing disturbing images before you actually, you know, see them, this is useless. Disappointed but not surprised.

Is Image Block X Safe?

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.

Image Block X 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.
High ****** *** ********* ** ******* *** ******* ******* ** ****** *** *** ******** ******

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 Add-ons Store, 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.

Image Block X has earned a fairly good reputation and likely can be trusted.
