1.6b1 vs. FF 9.0.1, scrambles Rated 2 out of 5 stars

Now I had to delete the whole brief.sqlite (while exiting and restarting FF) because the contents of the right don't show what should be there.

For example:
left category 1 -> contents category 23
left category 2 -> contents category 7
left category 3 -> contents category 12
left category 4 -> contents category 5

and so on - it's a mess

This review is for a previous version of the add-on (1.5.4).
