An extremely useful filtering extension to TBird. Provides easy, quick user-managed spam filtering, that runs periodically on selected folders -- an excellent value-add onto upstream email provider filtering, saves you time when dealing with your inbox and other active folders. Because FFS extracts spam domains so it will filter them automatically in future, it smooths your email handling every day.

This review is for a previous version of the add-on (0.2.0).

The idea of this new add-on is great! I think many people need to filter the content of any Thunderbird folder (not just Inbox). So, five stars :-)
A question though, can I select only some of the folders in my folder tree, when I create a new rule? And if I can, how can I?

Thanks so much, I'm glad you like the add-on!

Yes, you can select only specific folders. You can either click and drag with the left mouse button to select multiple folders, or hold **Alt** on Windows / **Command (⌘)** on macOS while clicking the folders you want to include.

Hope that helps, and thanks for the five-star review!
