Another session extension that I can't actually work out how to actually create a session! None of the buttons do anything except the hamburger menu top right and that doesn't have a "save session" entry.

Review Update 20-12-19:
Over the years I've come to regard Session Boss as critical resource for instantly assessing and organizing my research and work as well as maintaining a living history of my research.

I typically have more than 15 windows running with and average of 10-15 tabs each. At this moment I have 16 windows with 171 tabs,

Each window is related to a particular project I'm working as well as subjects of personal interest.

Session Boss is an integral part of my work flow and a huge time saver for me. Of particular merit is the session backup methodologies that Session Boss offers as well as the ability to export session data-I'm a developer. I hope others are using Session Boss for a work flow paradigm similar to mine even at a smaller scale.
"Finger tip" access to syntax references, type libraries, style guides. Electronic component suppliers, circuit design references, PCI bus specification standards. electronic components etc. Entertainment: Youtube sci-fi audio books, Favorite "real" (non-MSM) news sites and podcasts, Financial assets and trading brokerages and so on.

This is conjecture on my part but given a 50-75Mbs connection speed IMO a system with 16-32 gig and 6 cores would have sufficient resources to maintain 15+ open windows, 20 tabs each for others to Session Boss tab management to enhance their work (or play) flow as I do.
---Previous Review(s)
I love this extension! The ability to export/backup sessions is a feature that should NOT be ignored. Happily I found the export/import feature before having to roll my box back 3 weeks by restoring a system image.

Saves tab titles. When you click on a tab in a restored session, the URL is nowhere, no page is loaded. USELESS!

Very useful, but I'd like a configuration option to allow access to private windows only for manually initiated captures, not the scheduled nor the on-change ones. Also, it shouldn't clobber those few scheduled and on-change captures with the useless "0 windows 0 tabs" ones when browsing in private mode. Being able to adjust the number of automatic saves kept wouldn't hurt.

Does not work in fennec android

Using FFNightly (69.0a1 (2019-06-21) (64-bit)), last updated some seconds ago, I get: "This add-on requires a newer version of Firefox (at least version 63.0). You are using Firefox 52.0." Thats really not what I expected. :-(
The version test should perhaps allow for Developer an Nightly versions, too?

After half year of using this manager, i've simply lost everything after firefox auto update

Any other review than five star is just wrong.

I wish I could disable 15min intervals, I am just fine with once per few hours. But as long as it won't write to disk like crazy I am good.

Works. Once. After the second restart all Windows just open on the first screen, on top of each other.

Arguably the best session manager for Firefox. The only extra feature I would like to have is to connect to GitHub and save the session data in a repository.

With a little development, this extension could become the best session manager I've come across.

Off the bat, I'd say this extension is more for power users with multiple sessions.

In response to the developer on 4/23: (redacted)

Response 4/24: People use extensions in ways the developer didn't intend per se, in this case for managing saved sessions. IMO, text-based tab management is superior to thumbnails. Case in point: Session Boss has 3500+ users, TipTab 263.

Until I find another text-based manager, this is it. For an example of a text-based session manager elegantly handling the relationship between saved and running tabs, Session Buddy (Chrome) allows you to save and close individual sessions and tabs, regardless of whether they're open or not. If a saved tab happens to be open, clicking on its bookmark in the manager will take you to the existing tab. Closing it in the manager will close the open tab.

Thank you for reading my comments, and I hope you'll consider these features in a future release.

It seems to me an exceptional complement and all the functions that the own one implements, would be perfect if at least they worked the buttons of restoration that from their installation do not cause any effect, correct this and if not inform me of which complement or configuration I can have badly in the If it interferes, I would love to use its extension but if I do not see a solution I will eliminate it. Thanks in advance

Has great potential, look clean and modern. Might look complicated as first but it really isn't. The add-on can open into a pop-up or full page launcher. Can auto backup sessions. This session/tab manager is a mile ahead of all similar add-on on firefox.

Though, import URLs option is very limited. The add-on can only read it's own import format, which left migrate users in the dirt. User can't manual insert URL either.

FF v68.01 x64 - SB v2.11.2
This addon saves the current tabs periodically like the old Session Manager.

This version still has problems, as the restored tabs get messed up.
Luckly the pinned tabs still start unloaded, despite what the changelog says.

old reviews:

FF v67.0 x64 - SB v2.11.1
This version seemed to work correctly, but instead it has the old problem of some sessions restoring only a blank tab (expecially with multiple windows).

FF v60.6 ESR x64 - SB v2.2
This addon seems to work, but it restores tabs in a reversed order, which is quite annoying.

FF v66 x64 - SB v2.10
All seemed to work well, until a few minutes ago, when I lost all tabs.
The old correct sessions appear in SB, but if I restore them I only get an empty tab..

The bestest. But how to disable logging?

To complicated, that is all

This is really great, tons of useful options. Thanks for your work!

At the moment it is the best add-on for handling tabs in sessions when you also use containers. In other session tabs add-ons a session restore moves all tabs into the default container - I had 15 containers and approx. 350 tabs. It takes hours to move the tabs back to the right container - also because I did not found a good tool for "mass moving" tabs to containers. I had to do it one by one.

I made a littel test with the export / import function of session boss - it works! It did not crashes my tabs and containers. But importing into an other firefox (dev) does not work...I will ask the developer.

No matter which restore function I use, only the very first tab is being restored and the rest are being ignored. It looks like a great addon but it simply doesn't do it's job. For now, this addon serves me as a backup list of my tabs for when Firefox's sessions restore fails. Firefox Stable v66.

-- EDIT -----------------------------------

Cant seem to reply to the response so I'm editing my review:
No difference. After some investigation, it seems that there must be a Firefox preference (perhaps via my user.js file) that is set causing the "bug" (disabling all addons did not help). Debugging this would require moving user.js elsewhere out of the profile directory, then opening Firefox and going through about:config, manually resetting all modified preferences: not ideal. Any idea which preferences you addon relies upon to be functional (and note them on the addon's page)?

When using this addon with a new profile, it works as intended.
