Thankkkk youuu sienori !
To fix the "Open in new window" button problem, find on Google:
"open in new window doesn't work in Firefox105 1082"
(I can't put the link on this comment otherwise I would have done it already)

was able to save and load a session, but since i use tree style tab - the hierarchy of the tabs was lost. thankfully, the vertical order was preserved, so only the 'groupings' were lost.

honestly, it was not a big deal at all. (took less than a minute to put them back into groups manually for quite a few tabs)

i don't honestly expect a third party extension to play nice with every other third party extension - that would be crazy. as far as i'm concerned, this extension did exactly what it said it would do.

nice Session Buddy alternative

very nice and simple ! if I may : a drag and drop feature between session would be even nicer !

Just wanted to drop by and say thanks. The addon has saved my ass for so many times when Firefox decided to wipe my last session's tabs.

Great add-on, but ... When I restore a window, the order of the tabs changes. Is threre a way to fix this ?

This really is amazing, just ******* amazing. It has google cloud sync, but I'm scared to use it.

An amazing tool. The man who invented it is the hand of God. It is foolproof. It can be mastered quickly. It is simple. Most of all, it's smart. I used to have trouble renewing sessions all the time. Now I am mega-satisfied. Man - you are great!!!

Does the job perfectly.

Perfect. The best
