If have discovered that if i have a Message Filter directed to a folder, it will work fine if the parent of the destination folder is open. If i collapse the parent of the destination folder, Mozilla will not find the destination filter and will desactivate the Message Filter. So in conclusion if i want to use the filters i have to open the coplete folder tree.
What build are you using? Are you directing it to a local folder? See bug 115228
Yeah, ok... but then is the bug corrected in build 0.9.9?... because i'm working with 0.9.7...
Yes, 0.9.9 should include the fix. Marking this a duplicate. *** This bug has been marked as a duplicate of 115228 ***
