Features & Capabilities

Get the peace of mind that your open pages/tabs are not accessing the internet while their window is minimized. This saves some of the computer resources. Firefox automatically reduces the javascript timer frequency when the tab is in the background, but does not prevent it from accessing the network. With this add-on you get the added benefit that a tab in a minimized window is unable to transfer any data over the net.

Notes:

This add-on does not terminate connections that are already established when the window is minimized. It just prevents new ones.
For a more radical solution, try the add-on "Auto Tab Discard" by Richard Neomy, which totally pauses the processing in background tabs.

Is Offline when Minimized 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.

Offline when Minimized requires a few sensitive permissions. 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.
