Features & Capabilities

Load Background Tabs Lazily is a powerful Chrome extension designed to optimize your browsing experience by controlling the number of background tabs that load simultaneously. Inspired by the Firefox add-on "Load Tabs Progressively," this tool queues new background tabs, allowing only a specified number to load at one time. This prevents your browser and CPU from becoming overwhelmed, especially beneficial for users with slow internet connections or those who habitually open many tabs at once.

The extension blocks loading for HTTP(S) background tabs beyond the set limit and dynamically manages the queue to begin loading the next tab as others finish. Accessible settings and commands can be managed via its toolbar button or options page. Please note it requires broad permissions to manage tab loading effectively and is best suited for use in non-private contexts. With a focus on enhancing performance and reducing resource strain, Load Background Tabs Lazily is a must-have for users seeking smoother, more manageable multi-tab browsing.

User Reviews

I just wish there was a option to select max number of tabs to load beyond which the tabs will remain unloaded until selected, right now it will keep trying to load all the tabs in the line one after the other when the previous tab has finished loading
