dont restore automaticaly previous session

[zefilipe]

Hi,

Since the last update of Tab-groups addon (2.14), and Firefox update (53.0.3),
Every times i open firefox after windows starts, it asks every times if i want restore last session !
And before it restores automaticaly the previous session !

I use Session Manager addon, a long times, before using Tab groups ... !

Regards

Workaround/solution

In preferences for Session Manager:

• at shutdown, ask whether to backup the current session
• at startup, load nothing

– and in preferences for Tab Groups:

• suppress the groups view warning about non-restoration of things from last time

Tested successfully with versions 54.x and 55.0 of Firefox on FreeBSD-CURRENT. YMMV.
