Rated 5 out of 5 stars

FYI Pearl Trees options are stored at extensions.bro_toolbar in your about:config file. Helpful for all OPIE users. In OPIE's Configure tab, under Pearl trees, double click "preference root." Where it says (Unknown) type in extensions.bro_toolbar and click save. Voila! Pearl trees options will be backed up.

This review is for a previous version of the add-on (5.1.9).
