整理成树状标签的功能确实很好用，但是将其调整为树状视角时，会出现标签页被被重新打开的情况，这会导致历史记录被重复记录。

Abilty to work

Edit: My last review was an error I made... I found out, that under specific circumstances the data either of Tree Stye Tab (-> TST) or Simple Tab Groups (-> STG) can become corrupt, which makes them behave "strange". I assume it was STG, which caused the issue, because when deleting a few big, but useless groups they shown further strange effects, which vanished after deleting them completely.
Forget my 3-Star-Rating, and my apologies!

There's a rare incompatibility with Simple Tab Groups (->STG).
When saving a session in STG, the tree structure of Tree Style Tab (->TST) get lost completely and as a result the stucture is gone.
This happens on :
Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0
OS Linux 6.1.0-7-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.20-2 (2023-04-08)
OS Theme
and is a quite new problem.
Unfortunately I have no real idea how to check, which of both AddOn's produce the "error"...
Does anybody have an idea?
BTW... the rating will be reset after solving the issue, because I know this AddOn since a long time now and used it many times... sometimes in the past though it came to my attention, rhat there were some incompatibilities from time to time - that's why I post this message here and in STG.

I coundn't live without it during years. But now, Too much reported bugs that never get fixed, too much CPU & RAM hog, need to install TST addons, with reported bugs that never get fixed.

SideBery is way better, and stable !
