User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:11.0) Gecko/20100101 Firefox/11.0 Build ID: 20120310010446 Steps to reproduce: I create custom filter action using nsIMsgFilterCustomAction with property isAsync = true, that calls copyListener.OnStopCopy(0) when action is complete. I add it to filters actions list using nsIMsgFilterService.addCustomAction function. Then I crate new filter in Thunderbird and add 2 actions: my custom action and any another buildin thunderbird action. Then I run this filter from Tools menu. Actual results: My custom action completes successful, but following actions from the same filter are not run. Following filters are run. Expected results: The following after custom actions should be run.

Egor, have you resolved your issue?

(In reply to Wayne Mery (:wsmwk) from comment #1) > Egor, have you resolved your issue? Mery, unfortunatly, no, I haven't. I still use synchronouse method.

This issue, like many others associated with manual filters, will be resolved by the patch that I am doing on bug 695671, so I am going to dup this.
