About this extension
Note: Lumno is fully open source and built with privacy in mind. It does not collect or upload any user data. To enable search across your browsing history, bookmarks, tabs, and current page information, it requests the necessary permissions. All related processing stays local by default.
Lumno is a lightweight browser search and new tab extension. You can open a search overlay from any page with a keyboard shortcut to quickly find tabs, bookmarks, browsing history, and frequently visited sites. The same search experience is also available on the new tab page, so you can get where you want with less switching.
