Rated 5 out of 5 stars

Please update plugin to FF 57. I lost about 68 windows. It's horrible from mozilla to block this plug-in.

just removed ff57 and installed ff 56.0.2 Fuf. My tabs are saved. Yeah! Just switched off FF update.
What else could I do? Unpleasant situation

wow!
FF Quantum 57.0.1 CAN SAVE TABS!!!
Now it's no necessary to use plug-in to work with a lot of tabs.
Just update FF to 57.0.1 and be happy =)

This review is for a previous version of the add-on (0.8.1.13).
