User Reviews
Exellente, le seul probleme est quand j'ouvre une video (par example) avec le bouton droit de la souris dans un nouvel onglet, si le dernier existe firefox switch vers le nouveau onglet, ce qui me dérange beaucoup car j'aimerai ouvrir plusieurs onglets sans etre switcher sur un autre.
Excellent, the only problem is when I open a video (for example) with the right mouse button in a new tab, if the last one exists firefox switches to the new tab, which bothers me a lot because I would like to open several tabs without being switched to another.

Wonderful extensions, does what it says on the tin. I was looking for a "reuse tabs" extension; detecting dupes is much less disruptive. Thank you!

Is Duplicate Tab Detector Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Duplicate Tab Detector requires a few sensitive permissions. Exercise caution before installing.
