Features & Capabilities

This is a simple extension that blocks images exceeding a user defined file size.

Large Image Blocker helps you to:

save bandwidth
increase performance
save ram

If an image is blocked you will see an alternative text defined in the HTML alt-attribute. If the alt-attribute is missing, you will see a broken image symbol. But there is no placeholder of the missing image at all if it is integrated as a background-image or has neither an alt-attribute nor HTML dimensions.

Note: Images that are already in the browser cache are not blocked.

Known issues:

Downloads ("save image as…") are affected, too.
Blocking does not work when the url of the tab is directly pointing to an image. So if you right-click on a blocked image and select "view image", it will be displayed as usual. (This seems to be an issue in the firefox extension api.)
The extension relies on the HTTP Content-Length header field. A few websites do not set this field so that blocking does not work there.

Is Large Image Blocker 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.

Large Image Blocker requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

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.

Large Image Blocker has earned a fairly good reputation and likely can be trusted.
