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!

Found that DTD works well when I'm on a tab binge. However it fails on magnet links.
It has definitely improved my browsing experience.
It would be nice to have an option to close the window when all duplicate tabs have been resolved.

This is probably one of the most useful extensions I've come across. For online shopping and board forums, just open whatever products/topics you like and it will automatically close duplicated tabs instantly, saving so much time and headaches. You have to set them up a bit. If you don't know how to write regex, ask an AI. For example, with Amazon you can use ^(.*?(?:dp|gp\/product)\/) to compare only the ASIN in the URL.
A few quirks: some params it doesn't recognize; if you mass-open bookmarks from the same domain, because the tabs aren't loaded completely, it will mistakenly close them all but one if "auto close dupes" is on.
I also recommend the extension "ClearURLs". It removes almost all trailing trackers in an URL keeping it very clean.

My only objection is that tabs with the same title are considered duplicates (which is completely illogical) and this behavior cannot be disabled. Moreover, when I tried modifying the source code and installing the extension locally from file, it stopped detecting duplicates altogether even though the modification was straightforward and I'm pretty sure it should have just worked (I simply commented out the `else if (existingTitle === tab.title) {...}` block).

This is my first extension review, but I want to express that this is the first tab de-duplicator extension I've encountered that performs this straightforward task in a streamlined and intelligent manner. Thanks!
