Doesn't work at all. Don't waste your time. This extension should be removed from mozilla store, because it doesn't work and 4 years not updated.

[Edit:] This stopped working for me with FF v6.6.0.5, but I've just tried it again with 6.9.0.2, and everything's fine! It's an excellent, simple, elegant extension that lets you save and restore any FF sessions you wish—so what's not to like?

Es efectivo tal como se detalla, forma fácil y sencilla de salvar y recuperar todas las pestañas de una sesión, esperemos mas funcionalidades, seria interesante que un futuro quede integrado al Firefox. Thank you!

This only worked the way it says it should once or twice. I have a research job that had 56 tabs open in about 6 windows. Even though I have FF restore my tabs and windows, I have this extension as a safety net. So when that whole session did not come back, I used this extension to get a similar saved session. FF went bonkers. The "restored" saved session opened a new tab, then duplicated itself and the new tab action about 25 times. Restarting had no effect. It's just broken and buggy. You should not rely on this to save your work! I now have to dig through hundreds of entries in my history to get that work back.

Hate to repeat a manta but Simple & Effective, but that to me, is great compliment - thank you Oh, my Firefox has a light background - could you make it so your product icon can be changed to a black symbol - I didn't see any options for that? Thanks again.

So far I like this much simpler solution to Session Manager. Had too many corruption issues with SM maybe because of the extra features. Just want to save a session and restore which this does fine.
Would like to see it automatically save the session on exit and an option to restore a session on browser start up.

Does what it's suppose to do

Simple and effective.

The core function of this extension is very useful. In the past I would put specific bookmarks in a separate folder, just so I can use "Open All in Tabs" feature. This extensions takes care of that.
The UI can use some improvement. Here are some suggestions:
- Save sessions more easily, i.e. type a session name and finish by hitting Enter on the keyboard, instead of reaching for the mouse to click Save. This breaks the flow of using the keyboard.
- Close the session window automatically after saving a session, or make it an option, because 99% of the time after I save a tab session I don't need to do anything else in the session window.
- Restore a session by SINGLE clicking a button. The double-click loading does not feel natural in a browser, where everything else requires a single click.
- Quicksave button would be nice.
- Fix the size of the saved buttons. It seems that the buttons extend horizontally from one end to the other, so if the saved name is very short, you have a long invisible bar spanning the whole width of the window. I don't want to worry about accidental clicking on the empty area, which isn't really empty.
- Attach a date to each saved session name. Maybe as a tooltip. More info would be useful. Make the list with multiple info columns.
- View the saved URLs in each saved session without actually opening it. Maybe display the list of URLs as a tooltip when scrolling over each session button.
- Option for automatic saving at regular intervals would be nice, but not necessary.

I'll give this 5 stars because it's a brand new extensions and the developer has promised to improve it.

Update: About opening a saved session... The first one I open always requires two clicks, but every following one requires a single click. Strange.
Oh and thx to the author for considering user feedback. This is why the mozilla community is so great!

Waiting for the UI update

5 stars and one star on your repo!

Useful!
