Bug in latest release: Open all dials

With the FVD Speed Dial release from 9th october there is a bug with the open all dials feature.

Currently I have 4 groups with serval dials. The first group contains 6 dials and I usually open them with this feature "open all dials".

But with this release if I use this feature the dials of this group opens + beside a secind firefox window opens with the dials from other groups. The weird thing is that the wrong dials are not open all at once, it opens with a delay of 10 seconds and each one closes itself before the next one opens.
