Update notification made Firefox loose all my tabs

[Spirogira]

When I started Firefox toay it came with those instructions on how to set Proxyswitcher (never had seen it before), but Ff also lost data on all my more than 1000 open tabs.

It may have been some bad interaction with Tab Groups, my most beloved and necessary addon.

So cheers, I'll see if I recover my tabs.

Just recovered them from a recent backup.
