Great add-on, could be Cloud based (sign in with an account to sync across devices), also auto close tabs after a certain time and save to a list. And use a thumbnail snapshot of each webpage saved in the list.

This tab seemed cool & useful at first, but then it's limitations started to rear their ugly head. I haven't quite been able to determine if this addon is made for power users or not. I dumped upwards of 700 tabs in here. What's readily apparent is sorting was not thought about in this extension. It's a bit cumbersome & requires too many steps. In addition, at this level, things seem to break: I'll send 10 tabs at a time to a group & it just does nothing, refreshing the page. It...sort of works? I'll have to see if there are any conflicting add-ons (e.g. uMatrix or uBlock) that cause issues. Otherwise, I've set myself back the equivalent of months by using this.

Edit: *sigh* I've adjusted my review, as I realized there's a toggle in the options to 'silently' ignore duplicates. Perhaps this shouldn't be silent for those of us who are coming from other tools like TabGroups & TabGroups+. I'm still leaving my review in-tact, as I think the developer will appreciate some of the suggestions. Or not. :-)

Also, I will say one thing. As a result of installing this add-on, you realize how fast it is to just 'WOOSH', send many webpages into oblivion. Kinda neat.

from what I see it's a good add-on, but It takes time to move all tabs from one group to a different group. If you would add a feature to select multiple tabs by clicking on a tab, holding shift, and clicking on a different tab so all tabs between those two would get selected (just like it works with files in windows explorer) it would make working with this add-on much, much better and increase effieciency greatly.

Geschwindigkeit wird deutlich erhöht ! Übersichtliche und Praktische Sache

Hello OneTab Team: First of all, I want to thank you for this wonderfull Add-on, I just have a little inconvenient, the favicons comes from google, and I want to keep away from google so I try to block everything from google including the favicons of onetab that comes from google, and I can not see any favicon, Is there a way to change that?.
Thanks again for the add-on.

nothing

Can't give 5 stars yet until I've used it for more than a few days

Je trouve cette extension vraiment extra, dommage que l'on puisse pas intervenir sur sa mise en page, en tout cas merci pour votre travail.
;-)

OK, turns out I was wrong, although it seems to have started when I started using OneTab. I'm rating it 4 and try and start with a fresh profile for FF Quantum. Will see what happens..
