One of the best add-ons, I use it every day.
Open tabs is better than bookmarks, I use bookmarks only as backup.
I get more creative when using open tabs and continue where was yesterday.
Session manager have saved me 99% after a firefox crash.

Use Waterfox where old add-ons still work!
I use the portable version, you everything wherever you go...
Waterfox is actually faster and more stable then FF57.

Dump FF57!
