I already use it for long time. great for my 800-900 tabs.
firefox update to 57, with no warnings...
firefox say TST is the same and took my session manager.
now all my trees become flat !!
I tried to use the migration cmd tool on the last session file, but it give access denied and also the exe can not be erase from my folder :-(
I also does not understand all the config in the advance section of this add-on.
just to mantion, it keeps new trees as created.
I could not find firefox 56 download, in order to downgrade.
how can I get all my tree structure back ?
TST 2.2.8
thanks
