Почему после закрытия панели, перестаёт работать инверсия открытия вкладок!!!!!

First time user. Looks good and seems to work fine with the Containers extension. Needs a bit more polish which I'm sure will come as webextensions matures on Firefox. Thanks for the hard work! :)

ok

Nope. This will not work until the horizontal tabs can be eliminated. It is way too odd to have two tabs areas showing.

Io non voglio vedere le schede in alto. Spero che questo problema sia risolto in futuro.

1. I want the bookmark panel to be on the left, and the tabs panel on the right. How to? (Previously everything worked)
2. I do not want to see the tabs panel at the top and right at the same time. How to? (Previously everything worked)
3. Where is Russian lang? (Previously everything worked)

This was great add on but for some reason I can't hide the tabs as I was able to in previous version of Firefox, so not too how long I'd put up with seeing tabs at the top and on the side. I think Firefox need to do something about hide the top taps too. But will carry on using the add on and hopefully the updates will resolve it.

Thanks

Well, it's the best work around so far until a true tab-grouping add-on is developed for FF 57. It's the whole reason I use FF. Wish you could label the parent tabs something else than the parent website. For example, "Everyday Stuff" or "Suppliers." We have several suppliers and different types of suppliers so it would be nice to label each Tree like the tab groups of 56.

I use this as a replacement for grouped tabs in Firefox 57. Actually it's better than grouped tabs since you can't have nested groups. With this Add-on you can.
But the Add-on really needs an option to NOT open new tabs as a child tab when I middle click on a link. Opening a link from a website often but not always says something about the hierarchical relationship between those tabs. When I click on a link in a list of search results that makes sense. When I click on a "see also ..." link at the bottom of the page of some documentation or on a link to related videos on YouTube it's just nasty that those new tabs always become child tabs of the current one.

Отстой. Зачем горизонтальные вкладки оставлять, если есть вертикальное дерво вкладок? Совсем Firefox обхромился.

Tried to make the new version work with 57, but it doesn't. Reverted to 56.02 to resume using the old add-on, which does work.

Why is Mozilla killing off its add-on ecosystem?

- doesnt work on the last stable version of Firefox, ver. 56
- in ver 57 there is a number of differences with regular behaviour:
cant make the tree style tab smaller than some limit, which is too large for me
top line tabs are not removed (what is then the point of having this extension?)
Hope the extension owner and the firefox team will fix bugs fast. without this extension there is much less reasons not to go for Chrome

Used with Firefox Dev build: I really enjoy this add-on. I love the premise. Stability seems iffy: (1) I sometimes observe the parent tab separated from its children, i.e. there will be tabs in between the parent and the child at inconsistent depths; (2) I have observed once in the first few hours of using it the whole sidebar becoming blank and unusable, requiring a restart. I also have one suggestion: I find that this add-on simply supersedes the vanilla browser tab strip, so it would be nice to have an option to hide the default horizontal tab strip.

Tried every setting I could to prevent child tabs from every being closed, but I was still losing tabs when closing *some* parents. Tried promotion, dummy, only when tst is open, etc.

Когда уже выйдет версия под последнюю лису? Я годами использовал аддон и без него сейчас как без рук. Поставлю 5, когда обновите.

Either crashes or intentional closures.

Awesome otherwise.

Working in 58, but after I restart, all nesting is gone...
