Unable To Display Full Screen Rated 4 out of 5 stars

The display screen is not fully accessible.
Like when options are changed and the save option at the bottom of the screen is not visible to save the new options.
Hope that this is remedied in the near future.

Important add-on but needs improvements Rated 3 out of 5 stars

This is currently the best session manager on firefox but sadly it is in desperate need of a web interface and UI improvements.

Excellent Session Manager Rated 5 out of 5 stars

Version 0.8.1.13pre20161130b works perfect on FF 53.0a1 (2016-12-12) (32-bit), backup and restore tested for multi-windows with 107 total tabs. Thanks.

Almost perfect, but needs some features. Rated 4 out of 5 stars

Great idea for an extension and works well for the most part, but I feel it is really missing some key features. Number one, please add an option for deleting a session by just right clicking on it and hitting delete from the main Session Manager window. Number two, I want to be able to save just ONE session that saves automatically. It gets too confusing having multiple sessions. Finally, please add options for increased font sizes, so you can see all of the tabs clearly with larger fonts from the main Session Manager window. By far the most important addition would be the ability to delete sessions from the main Session Manager window, rather than having to go to the delete sessions menu. It would be a huge time saver! Thanks for making a great and very useful extension!!

Falls frequently. Rated 2 out of 5 stars

It falls frequently. First sign of fall is incorrect display of pages (black rectangulars). After browser closing the following message appears:
The session/window data is corrupted: undefined(undefined)

Очень сильно грузит систему, плюс нестабильно работает.
Спасибо за наводку на Tab Plus.

Multiprocess support Rated 5 out of 5 stars

Please add multiprocess support

Amazing add on Rated 5 out of 5 stars

It backs up so many different sessions making it very easy to restore the browser to the state you just lost.
Thank you very much for making this add on.

muy util, si eress de los que tienes 1000 pestañas abiertas te evita muchos disgustos.

e10???? Rated 5 out of 5 stars

great addon but looking for an alternative that supports multiprocess

Good and bad Rated 3 out of 5 stars

Great for main computer, indispensable. But for my 15" 1280x800 laptop completely useless, as the bottom half of the Options panel is cut off making it impossible to save any options... and I have to close Options via Task Manager because the top half is cut off as well.

If you're a power user don't trust Session Manager Rated 1 out of 5 stars

I love Firefox and I love all the effort people put into the main app and all the add-ons. I really do. Session Manager is OK if you save sessions manually but the crash session saver doesn't work if you're a power user, even when you check the "save session" flag under tools. So for example (and this is the most recent of many over the years and just tipped me over the edge to write this review) after a crash this morning, up popped the Session Manager asking me if I wanted to restart the crashed session (2W 90T). Clicked yes. 13 tabs were reloaded. Darned annoying.
[Firefox 49.0.2. MacBook Pro 512GB top end. MacOS Sierra 10.12] Had the same results with top-end Windows PCs also.

No mobile usability? Rated 4 out of 5 stars

Session manager is a very useful and versatile tool. I really appreciate using it for my desktop.
BUT: I really really would want to use it on my Android devices, too. Now unfortunately, although listed in the Android addons section, I cannot install it onto any of my android devices. It can be downloaded properly, but the dialog to allow installation afterwards is missing...
Anyone able to solve that?

Session recovery issue after Firefox 49.0 update Rated 5 out of 5 stars

As a long time user it's been a great favorite add-on because of its recovery capabilities. Unfortunately, it no longer recovers saved sessions since Firefox 49.0 update [Running: MAC EL CAPITAN 10.11.6 (15G1004)] . Recommended fixes have not worked so far, but, will keep trying.

e10s ? Rated 5 out of 5 stars

It seems it doesn't support e10s but since e10s is disabled on my profile, I couldn't say if it still properly works despite that.

I hope it will be compliant with future firefox release. I love it. Do you plan to update it?
