Essential add-on Rated 4 out of 5 stars

I hope it will be adapted to the new API. Sometimes I have the problem that my browser becomes completely unresponsive for a minute or more because it needs to reallocate memory or something like that. I then frantically click on the close button which takes ages too to react. Firefox then closes with a crash and the next time I open it, Session Manager shows me the latest saved entry as completely blank with zero tabs in the list. Of course older entries are missing some tabs which I opened since then...

gone from nightly Rated 5 out of 5 stars

Doesn't work anymore with FF nightly, not even when forced to be loaded. Sad.

one of the most useful browser extensions Rated 5 out of 5 stars

For me, this Add-on works like a charm and I hope the developer will keep his project alive in future!

Juste INDISPENSABLE

Joloda has no clue Rated 5 out of 5 stars

I've been using SM for years on Firefox. I have used it with up to 125 tabs in 7 different groups without a hitch. The built in feature to keep multiple sessions is great, allowing me to transport sessions to multiple computers / share across multiple profiles. It really is a must have addon for anyone using Firefox.

Now just patiently waiting for an update to work with Fx Nightly 57.0a1

Very bad and buggy with a lot of tabs. Rated 1 out of 5 stars

Doesn't work as intented, full of bugs with a lot of tabs. Many sessions cannot be loaded because the JSON files are corrupted.

Webextension compatibility!!! Rated 5 out of 5 stars

Don't forget to give webextension compatibility to this wonderfull addon!!!

fix 55.0b9 Rated 5 out of 5 stars

please fix for 55.0b9

An absolute necessity Rated 5 out of 5 stars

I don't know what to say other than this add-on is indispensable! Since I automatically clear all browser data upon closing Firefox, Session Manager has saved me from so much wasted effort of having to reopen 30+ tabs after crashes. It even works with the Tab Groups extension!

Love it but... Rated 5 out of 5 stars

Ever since a recent FireFox Developer Edition update, this addon and many others now say "Legacy" next to their names. I'm not sure if that's related to the issue I'm having, but now I can't use Tile Tabs when loading a Saved Session from "Session Manager". Everything gets screwy and Tile Tabs doesn't work correctly. Switching tiles as well sometimes lags and can't change unless "X"d out. Please fix this if you can. I'm reinstalling the Addon now in hopes it'll repair the issue. I tried doing that on TIle Tabs but no difference. I'm not sure if this addon is to blame for incompatibility or Tile Tabs, but please look into it. Otherwise, I love Session Manager! I'd hate to switch solely for this reason. Great add-on nevertheless!

Firefox 57 compatible? Rated 5 out of 5 stars

Wondering if it is already or plan to be a webextension.

Thank you very much!!!

Great saver :) Rated 5 out of 5 stars

Thanks for your effort!

Good Addon, One Caveat Rated 3 out of 5 stars

This is a good addon that I've used for some time now. The one thing I miss is that there is no longer a list of closed windows listed by the toolbar button that stays active between sessions. If you close all of your Firefox windows and then reopen Firefox the closed windows list empty. I am l looking for another addon that has this functionality but no luck so far.

Brilliant idea poorly executed Rated 2 out of 5 stars

After less than a day, Firefox will slow to a crawl, repeatedly flashing "not responding" every second or so. Eventually, after minutes or hours, this addon will crash with a notification that it cannot write to its database. The only fix for this is to kill the Firefox process and start over. Then you're good for another few hours of activity before you do the same dance again. I'm going to try TabMix.

One of the most useful plugins for Firefox Rated 5 out of 5 stars

It is not just a plug-in. It is a personal assistant. It only lacks online session storage for synchronizing multiple devices, but this can be solved by using Dropbox or a similar service.

Session Manager doesn't load sessions in latest nightly Rated 4 out of 5 stars

Hello
In latest Firefox Nightly (version 55), session manager loads empty window when loading a saved session. even though it displays list of sessions.

Very good complement! Rated 5 out of 5 stars

It has helped me many times, great complement to Firefox, continue with the development. Thank you!

Just works Rated 5 out of 5 stars

Thank you.

Best of its kind, use it every day Rated 2 out of 5 stars

Best thing is, I can save entire windows with tons of tabs of researched information. Also, I can retrieve those for later use. Also, it autosaves most crashed sessions, and saves sessions regularly at time intervals I choose. Really useful

But, at one point, Firefox last summer completely erased all my old session manager stuff with a horrid update that removed, not disabled, but removed without my permission all of my . Now, in version 5.2, Session Manager is inaccessable, add-ons, & all the saved windows/tabs in Session Mgr. I had to re-install a new Session Mgr., and start from scratch, with all the old data lost. Now, the latest problem is Session Mgr isn't working in Firefox 5.2, it freezes the browser when I click on it & then nothing works, have to re-boot the browser. I disabled Session Mgr. now, today, and am waiting for this bug to be fixed. Hope this bug is fixed soon. Otherwise, it's the most useful add-on I use & have ever used. Great for college students, high school students, and any kind of professional or amateur researchers who need to do research in their profession, or for their hobbies & activities. I'd give it 5 stars, but this new version of Firefox has disabled plug-ins, Java, Adobe, and all my images don't load.Thanks Firefox, for your wonderful coding these days!

Issues restoring the session Rated 4 out of 5 stars

The extension works nicely, however in the latest versions of Firefox it has issues restoring the session. On startup:
1) Browser opens, a dialog with sessions is shown
2) I double click the previous session. Either of the following happens:
- Browser still opens with a default session (pinned tabs only)
- The restored session appears for half a second and then replaced with the default one (like above)

After that I have to manually click on the diskete icon, select the previous session and reopen it. It ruins user experience when reopening the browser

Also, there're localization problems - my system's language is English (ArchLinux+KDE) with russian locale for metrics system and numbers format. Everything appears in English except this plugin. I consider it a bug in the pugin
