Native Lazy Tabs is a free browser extension for Google Chrome that speeds up the loading of the web browser by using lazy loading when it starts.
You may have noticed that Chrome's startup performance lacks severely if Google Chrome is configured to load the previous browsing session on start.
The core reason for that is the Chrome will load sites in any tab on start, regardless of how many tabs are open in the web browser.
If you had 50 or 100 tabs open in the last browsing session, Chrome will load these tabs on start. That's bad for the startup performance as you will notice lag while Chrome loads all of the sites. It is also bad for memory use, as all sites use RAM when they are loaded.
Most web browsers support a feature that blocks this from happening. Firefox for instance loads only the active tab when you have configured it to restore sessions, and will load sites in other tabs only on selection.
Vivaldi has the lazy load feature built-into the browser's startup settings (
vivaldi://settings/startup/), and Opera has a similar feature that is called "delay loading of background tabs" which you find under
opera://settings/.
Only Google Chrome, the browser with the largest market share, does not support this functionality.
