The same with 1:23.0.1.deb1-1, also with a new profile.

Here too!

I also ran into this problem.
Happy to help if I can...

I asked on #debian-next and at least one person said that this works on sid with version 23.0.1.
So it's likely broken somehow with Parabola and not upstream.

Maybe this is a clue.
When I try to "undo closed tab" using Pentadactyl add-on (hg6938), I get this error message: "'Illegal value' when calling method: [nsISessionStore::getClosedTabCount]".
This doesn't appear to be reported as a Pentadactyl bug, so maybe something to do with our Iceweasel customization?

this bug only exists in Parabola, I have libre-Debian and Trisquel on another partition sharing the same home and works perfectly with the same profile, in libre-debian, trisquel and Parabola I have iceweasel 24
