Works great except that it constantly updates, then announces its update all over my browser (opening tabs and all this stuff). What's worse, it needs to confirm permissions after every update, or the sync stops working. But it doesn't ask to confirm permissions, so the sync just stops working! Extension developers need to make some effort to understand how these things work, and should also be using their own extensions so they learn what goes wrong all day every day in the user's browser.

Solo desearía que su ícono fuese más lindo, así se vería mejor, ya que lo tengo colocado en la barra de herramientas permanentemente

Very good addon!
Does only save the active page for each tab. Having an option to save each tab history will be great, but it seems that it is due to a limitation of Firefox's API.

Good session manager, has good features. Sessions open fast. A problem for me after saving a fair number of sessions was slow opening time. I'd start FF and the TSM would not populate with sessions for perhaps 10-15 minutes. Is it loading sessions all that time? Perhaps should load auto-save sessions last? As said in another review, wording of how to save backups is confusing. Better wording: "Save location must be under the Download Folder (set in browser settings)."

最新版6.8.3だと、セッションを開きなおした時に保存した順番とは異なる順に展開されます。
保存時点でアクティブなウインドウのアクティブなタブだけ先（右）になるっぽい
具体的には一旦複数のタブを開いてセッションを保存、ブラウザ落としてセッション開いていくつかアクティブにしてもう一度保存、再度セッションを閉じて開き直すと再現できるはずです
12345の5タブ保存してあるとして1（今見ている）23（アクティブ）45（保存したのを開いたまま）でセッション保存して、ブラウザ落として開き直すと1（アクティブ）4523 として開かれます

The original tab order will be lost when window restored. I'll take quite a few time to rearrange it.

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.

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

нет возможности из открытой сессии добавить вкладку в одну из сохранённых ранее сессий. Тогда был бы полноценный заменитель онлайн закладок, т.к. синхронизация с Google — наше всё :-).

I love your extension but on latest firefox v76 it stopped working and lost all my sessions...doesnt shows me the open tabs so i cannot create manually either.....

It would be nice to be able to edit tags or make tags case insensitive. Sync would be great too. Tab Session Manager has evolved a lot. Great usability changes, keep it going!

Hello sienori, thanks for that nice extension. I like it very much, it works very good so far.
Only some features I am still missing:
-Edit: I found it ;-) its under settings / sessions = import older session
- an option to define a limit number for automated saved files which are generated in Backup folder - so that older ones will be deleted "automatically". Or at least user limit number and get a message popup when the limit is reached so everyone knows to start cleaning autdated saves.

Thanks in Advance an greets from Germany

And: plus an option to name automated saves user defined like "Autosave", because the title of the tab currently active is not very unique, the same with saved when "browser closed" or when "windows closed", so we can distinguish better between them.
