Write about my experience with this add-on? I wasted hours trying to figure out why I could have only one tab per domain. It didn't matter if the url was completely different. Utter POS because the PEUJ who designed it doesn't even know the meaning of "duplicate". IT MEANS "EXACTLY THE SAME", got that? Read again.

ne fonctionne pas

It keeps closing som4 local tabs on my network, basic local IPs. Nope.

Hours gone to waste because of this piece of crap. Instead of closing just duplicates, it closed all tabs that I had 2 or more of open. So for example, I had two copies of a tab. It closed them both. Ctrl-shift-T only goes back so far. I'm going to have to start all the way back at the beginning now. I can't even express my rage at this useless extension. I completely regret I ever got it.

Please optimize this extension for Firefox Android

It doesn't work well recently. It needs to be fixed.

As of October 2022 No longer functions at all. Removing.

Not a bad addon but could use a lot more functionality. For starters, it needs a whitelist for sites that are okay to duplicate, which is often necessary. Also, a simple "Close tab automatically" function really isn't the best way to handle a duplicate inadvertently being opened. For example, say you forget you've already got Google open and you type a search in the address bar (which I have set to auto open in a new tab). Rather than the new tab opening with the search I just typed, it switches to the old tab, with an old search in it, which is at first pretty disconcerting. In this case it makes more sense to close the old tab, not the new one, but again, maybe I actually do want them both open. There needs to be a white list. Did I say there needs to be a white list? There needs to be a white list.

RESPONSE TO DEVELOPER'S COMMENT: If you think I gave it two stars just for missing one feature, you didn't even bother to read the whole review. Two stars stands I now I don't even want to bother seeing if it's improved. You need to learn what reviews are for.

It's not automatic deleting the duplicate tabs as far as I could tell

facebook , gmail etc exclude list feature dont work...........................
