>>> "IndexedDB" ERROR MESSAGE ON NEW INSTALL!!! RESTART THE BROWSER TO FIX!!! <<<
#. IMPRESSIVE SESSION MANAGER - AFTER RE-OPENING, HAD ALREADY A SAVED SESSION (NOT CURRENT) FROM 8 HOURS AGO WHEN I PREVIOUSLY OPENED BROWSER!
VERY COOL!!! :D ;) ;D :P :B

Greate addon. Let's add "recomended" badget?

Génial ! A tout récupéré après un vilain crash.

I use it approx 3 years! The Best!

WARNING: this addon is not compatible with «Simple Tab Groups» and would pull all grouped tabs into one window. Luckily, STG has a backup function.

Firefox can be garbage with saving your sessions. Can't count how many times it has failed for no damn reason, and this add-on has saved me countless headache. Definitely a must have

Great addon, has been updated to issue features/fixes addressed to be lacking in the previous reviews.
Seemingly the most modern and useful session manager.

This is a great add-on that is very useful. It would be even better if it were compatible with Tree Style Tab, and restored not only the tabs themselves but their tree structure!

I would like to give five stars to this add-on as it's the best session manager but the interface is awfully becoming worse and worse:

- You no longer can select tabs nor windows to be opened. It looks like you can only remove tabs from the tree before opening a session, in which case you destroy the structure. Sessions lose the original structure and you cannot use them in the future as they were

- The maximum width of the side pane is 800 pixels, what does not leave room to access any of the valuable tools and options, such as rename a session, access the menu, see full tab description, add tags, open/delete a session

- You are somehow forced to configure the add-on to open the panel on a new tab which is inconvenient

The best FF session manager at the moment.
My wishlist:
- Could be a little faster at startup
- FF sync support would be great.
- Possibility to rename saved sessions
