基本满足侧边栏要求。但是有问题：
用firefox color 自定义颜色时，“树状标签页“这里无法自定义，这就很尴尬，侧边栏和工具栏中间永远隔了一块。
对比edge。edge的侧边栏目前来说应该是最简洁易用的了，外观功能简洁，固定标签一目了然，搜索标签右键一步到，隐藏边栏edge还显示图标，不得不说edge在设计功能易用上花了心思的。
希望作者参考一下edge垂直标签栏做一些优化，谢谢。

Like it.
Gives me the freedom to use those extra couple of cm's at the top of the screen, by utilising the side of the screen a bit.
Been using it now several years.

Overall great, but it becomes too laggy when many tabs are opened.

Great extension for managing a bunch of tabs!

One annoyance: Sometimes when I click on a tab, if I'm moving the mouse a little it'll put the tab in a new window. Can be a little annoying to move it back if it has a bunch of branches.

Otherwise, great stuff!

Best tab sidebar, but can i use it without tree?

Love the extension in general but please let us turn off the new 'New Tab' context menu option. We are used to 'reload' being the top selection and the 'New Tab' at the top has changed our workflow. Thanks!

Since months I use your TST, but there is a problem:
When opening a lost session via Tab Session Manager the tab order ist lost.
Does nobody have this same problem ?
Perhaps its only an adjustment.

I did tests now by saving and reopen of a (one) window:
Reopening works fine when active tab is the most right one.
Atherwise only the tabs left to the active one are correct after reopening. The tabs to the right of the active one are reopened in wrong order.
What I think also, saving is not the problem, it's the reopening !
Whould be nice to hear if you found that as i do and more nice if you would correct this issue.

*** an older rating:
It's a must have for me, BUT there is a bug when FF 68.9.0esr crashes:
I had a structure with about 50 tabs. I closed this window, left an other open. The closed window was automatically saved in "Tab Session Manager". Shortly later my Browser crashed. I thought no problem I have saved my important window and structure.
. But NO, after FF restart there are no chronicles within FF and after restore from "Tab Session Manager" the structure was lost.
-> This loss never happens when I closed and restarted FF.

My questions:
-How do I get back my structure ? or
-What must I do that in this situation my structure is automatically restored ?

Hopefully you are able to help !?! (running OS is Windows 8)

NOW I found a solution for me. Perhaps you will correct this once:
I found out that a restore from "TabSessionManager" is mirroring the tab-order.
So when Firefox is crashing and I really have to use a restore from "TabSessionManager", I save again the restored tabs and restore it again.
-> A double-mirroring will bring it in correct order and "TrueStyleTab" brings back my lost style.

Conclusion: I think the fault is in "TabSessionManager" not in "TrueStyleTab"

Works great! Only thing missing is I'd LOVE the option to be able to see tabs / trees from all open windows and not just the currently focused one. Is this possible?

Does it have shortcuts?
