Summary

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'.

Read Before Installing

After this extension is added or installed, do not select 'Allow this extension to run in Private Windows'. This extensions Options page will open to the 'Permissions' section after installing. A user must select the 'Access your data for all websites' permission for this extension to function. Once the permission is granted, this extension may be turned on by clicking its toolbar button and selecting the 'Turn Off or On' command. The 'Access your data for all websites' permission allows for real-time content blocking on most web pages. As this is not a 'Recommended' (manually reviewed) extension, granting this permission is a security risk. This extension is best used in a profile or a non private window where data loss like passwords or personal info would not be very damaging, in case of rogue behavior.
