Can't do without it now. Sure it can use improvements, but a really great start.

great add on to save sessions please developer don't fuck up the add on is great as it is!

Bloody brilliant stuff. Thank you :)

amazing. bugged me at the end of december, re-installing fexied the issue. very good app otherwise

Works really well, although need to understand settings and that Firefox now has a similar feature biult-into itself, which saves users from many annoyances or even troubles.

Good to have both if closing browser with many windows happens often to you.

After may similar I tried, this one is most stable and for me do the job perfectly Thanks Sienori!

Useful addon.
Please create a sort function all tabs by url like
jkljlk.host1.url
jkljljgg.host1.url
jhg.host2.url
jhgjkh.host2.url

タブの保存に、素早く元のタブを開けるこのアドオンが大変便利です。
ただ、このアドオンのバグか、ほかのアドオンの影響かはわかりませんが、現在のウィンドウで開くと、一番左端にあるタブが、一番右端で開くようになってしまいました。
解決方法はありますか？
