Image Block Firefox

Image Block

Image Block adds a toggle button that conditionally blocks/allows loading of images on webpages. Blocking images results in faster browsing, especially helpful on handheld devices or slower connections.

Features & Capabilities

Image Block is a straightforward Chrome extension that adds a toggle button to your browser, enabling you to conditionally block or allow images from loading on any webpage. Designed with simplicity in mind, it boosts your browsing speed by preventing images from loading, which is particularly advantageous for users on slower internet connections or handheld devices.

Originally created for Firefox and reimagined for modern browsers, Image Block maintains its core philosophy: keep it simple and user-friendly. Its one-click toggle avoids complex settings or filtering lists, offering a hassle-free way to control image content. Besides improving load times, it also helps users avoid unwanted or sensitive images on certain webpages, making browsing more comfortable in various environments such as work or public spaces.

User Reviews

Image Block is praised when it works, especially for saving data and being easy to toggle. However, many reviews cite reliability problems (inconsistent blocking) and UI visibility issues (missing toolbar icon). Some users also worry about maintenance/compatibility with Firefox versions. Overall, it’s valued when functional but unreliable for many users and occasionally hard to use due to UI and update concerns.
Pros
  • Blocks images to save data/bandwidth.
  • Works as described on many sites when it functions.
  • Easy to toggle on/off via a toolbar button.
  • Considered an essential Firefox extension by some users.
  • Improves readability by removing images on pages (e.g., homepage reading is clearer).
Cons
  • Reliability is inconsistent: multiple reviews report it does not block images reliably or at all on some pages.
  • Toolbar/icon visibility is problematic: users cannot easily find or access the toggle in several reviews.
  • Occasional maintenance/compatibility concerns: some users feel the add-on may be outdated or not maintained, affecting functionality.

Is Image Block 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 requires a few sensitive permissions. Exercise caution before installing.
