Hi @n8marti,
Sorry for the late answer. It seems that you are using an old version of TB and I cannot replicate this issue in the last version of TB and of the theme.
Which version of the theme are you using? I can give a look too see if a quick fix is possible

I'm using the latest TB available from the Ubuntu repos, so I'd have to update it from a different source to get a newer version, which I'm a little reluctant to do because I rely heavily on TB for my day-to-day work and would hate to run into some other unexpected problem.

My extension version is 3.3, updated on Jan. 24th. But I'm fairly certain that I was having this problem before that update, if that's helpful. It's not a serious problem: I can just make sure to leave the filter box empty when I quit Thunderbird and everything works fine. I just sometime forget!
