About NoDup
Same link. Same tab.
NoDup reuses a tab you already have open, so you can pick up where you left off.
Choose when to reuse tabs:
• Links opened from other apps.
• Links opened by webpages in new foreground tabs.
• URLs entered or pasted into a newly opened tab.
Each option can be turned on or off separately.
Keep your tabs where you want them
Switch to the existing tab, or bring it to the new tab’s window and position. Pinned tabs stay in place.
Change your mind
Undo a reuse from the toolbar prompt or extension popup. You can also allow the next duplicate, exclude a website, or pause NoDup.
See your savings
Track how many tabs you’ve reused and your estimated loading time saved. Estimates use each website’s recent load times, with a 3-second fallback until enough samples are available.
Stay in control
Opening a page’s own URL in another tab is always allowed. Navigation within an existing tab stays unchanged. Eight interface languages are available.
Local by design
No accounts, analytics, or data sent to a server. Settings and limited hostname-based timing samples stay on your device.
A few things to know
Link-source detection is approximate, and a new page may start loading before NoDup acts. Undo opens a fresh duplicate; it cannot restore the closed duplicate’s page state. If Chrome does not show the automatic prompt, manual Undo remains available for 60 seconds.
Requires Chrome 127 or later. Incognito is not supported.
