Load Background Tabs Lazily
Allow only a specific number of new background tabs to load at one time.
What is Load Background Tabs Lazily?
Load Background Tabs Lazily is a Firefox add-on that allows only a specific number of newly created background tabs to load at a time, improving browsing performance and reducing CPU usage.
This extension tries to duplicate some of the behavior of Load Tabs Progressively, an addon that has not been updated to work with newer versions of Firefox.
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 tabs with http or https URLs are blocked from loading by this extension. In many cases, the URL to be loaded in a new tab can't be viewed by this extension when the tab is created and added to the line. Tabs with non http(s) URLs that won't be blocked and that were added to the line will quickly be removed when the URL is viewable.
Various commands or settings for the extension can be accessed in the toolbar button popup or in its Options page.
Version 1.33 of this extension will work on Firefox versions 52-109. It can be found by clicking 'See all versions' under 'Version History'.
