found that the latest version of CC (3.04) was compacting "global-messages-db.sqlite", ie global search database in Thunderbird. I know that some people complain about the fact that this file's size increases constantly, but I'd rather that CC wouldn't tale care of it. And I can't see Thunderbird in CC application scope in the UI. So how can I disable that checking? thanks.
...but wait... having a closer look at CC Firefox section, I see that it's in fact called Firefox/Mozilla, meaning that it may include Thunderbird at least for the setting "compact databases" usually restricted to urlclassifier.sqlite in Firefox. So I may have the answer to my question. Remains that I would have prefered two separate settings for FF and Thb
