About this extension
Whenever you find yourself with too many tabs open, click the OneTab icon to convert your tabs into a list. When you need them again, you can restore tabs individually or all at once.

By moving your tabs into the OneTab list, you can save up to 95% of memory because fewer tabs remain open in your browser.

Privacy assurance

OneTab is designed with privacy in mind. Your tab URLs are never transmitted to or shared with the OneTab developers or any third party. Domain icons for tab URLs are generated by Google.

The only exception is if you intentionally use the “share as a web page” feature, which uploads your tab list to a web page so you can share it with others. Tabs are never shared unless you explicitly use this feature.

Additional benefits

Storing tabs in OneTab can also improve your computer’s performance by reducing your browser’s CPU and memory (RAM) usage. Even high-end computers can slow down when many browser windows and tabs are open, since each open tab continuously consumes system resources.
