Load Background Tabs Lazily

This extension duplicates some of the behavior of an old Firefox extension that is no longer maintained, Load Tabs Progressively. Load Background Tabs Lazily places newly created background tabs in a line and allows only a specific number to load, while blocking the rest. A tab is removed from the line once it has finished loading. The first blocked tab in the line is then allowed to load. This extension was designed for users with slow internet connections that routinely open multiple background tabs at the same time. It also helps users that open many background tabs at once by not overwhelming their browser or CPU. Only background tabs with http(s) URLs are added to the line. Middle click (or Ctrl click) a link, bookmark, or bookmark folder to create background tabs. Various commands or settings for this extension may be accessed in its Options page or toolbar button popup. The toolbar button may be pinned by clicking the 'Extensions' button that looks like a puzzle piece on the toolbar. Permissions used: ▸ non-optional: 'contextMenus', 'declarativeNetRequest' (Block content on any page), 'storage', 'tabs' (Read your browsing history)*, 'webNavigation' (Read your browsing history) ▸ optional: '' (Read and change all your data on all websites), 'browsingData', 'downloads' (Manage your downloads), 'nativeMessaging' (Communicate with cooperating native applications), 'tabGroups' (View and manage your tab groups), 'webRequest' * The 'tabs' permission allows this extension to view the the url, pendingUrl, title, and favIconUrl properties of a tab.

Auto Tab Discard (suspend)

Increase browser speed and reduce memory load when you have numerous open tabs. "Auto Tab Discard" is a lightweight browser extension that automatically reduces the amount of memory used by open but inactive tabs, helping to conserve battery life on portable devices by disabling JavaScript code and DOM events on discarded tabs. There are two options on the extension's interface to either discard tabs or release discarding (the "x" buttons) The features of "Auto Tab Discard" are: * Improves browser performance and reduces memory usage by automatically or manually discarding inactive, idle, or forgotten tabs. * Includes a list of hostnames or regular expressions that can be excluded from auto-discarding. * Preserves the discarded state of tabs when the browser is closed and reopened. * Indicates the discarded state of a tab through the favicon or title. * Restores the state of a tab, including scroll position and text box content, after it is released from being discarded. * Allows for the forced discarding of specified hostnames. The options for configuring whether tabs should be discarded or not include: * Pinned tabs * Tabs that are playing media * The presence of a power source * Unsaved content or user input in a tab The available plugins for "Auto Tab Discard" are: * Release the discarded state of the next or previous tab. * Release the discarded state of all tabs in the active window. * Automatically discard all newly opened inactive tabs. * Store YouTube's timestamp before a tab is discarded. * Permanently delete (remove) old discarded tabs that are inactive. * Unlike the "The Great Suspender" extension, this extension uses the native method for discarding tabs, which means that even if the extension is removed or the browser crashes, your browser will automatically restore everything for you. https://webextension.org/privacy-policy/extension/tab-discard.html

Sloth

Automatically discards all tabs at startup, before they load, reducing memory footprint and unnecessary bandwidth usage. An open-source and light-weight chrome / chromium extension which ensures that tabs are lazily loaded. This plugin uses the discard API available since Chrome 54. All tabs except new tabs or "special" tabs are discarded. Discarded tabs are visible in the tab bar, but not loaded from the network nor kept in memory. If a window doesn't have a new tab, it is created and activated. This prevents any tab from loading during startup, unless you explicitly select it. Special tabs are those with chrome:// URLs, for example. Note: Where there are hundreds of tabs open in the session, a couple of them sneak through and become active. This limitation is due to the design of the browser. See https://github.com/hrj/sloth/issues/1. I found an extension called Native Lazy Tabs here. It was distributed under the GPL license. I adapted it and added the "new tab" feature. The icon is by Jaime Serra, distributed under the CC license.
