Trying to expand or collapse a group by double clicking anywhere but the arrow in the subject field does not work. When a group is collapsed, double-clicking on the "Today" group header in subject field will open a new Thunderbird window with no tabs open. When a group is already expanded double-clicking on the the group header row does nothing. Reproducible: Always Steps to Reproduce: 1.Set view to sort by "Date" and "Group by Sort" 2.Double-click on the group headers anywhere except the expand/collapse arrows 3. Actual Results: When group is collapsed, new Thunderbird window opens with no open tabs. When group is already expanded, nothing happens. Expected Results: Double-clicking anywhere in the group header row should expand or collapse the respective group, such as in Outlook.

Aureliano, do you also see this ?

(In reply to comment #1) >Double-clicking anywhere in the group header row should expand or collapse the >respective group, such as in Outlook. Why? In TB to collapse\expande thread you must click (*1 click*) on expand/collapse arrows. This because when you double click >Double-click on the group headers anywhere except the expand/collapse arrows TB open message (or messages) in tab or new window based on your option. In my opinion this is Invalid because the behavior is deliberate.

Reporter, do you still see this problem when using a current version of thunderbird? And if you do not, please close bug report by changing resolution to worksforme

RESOLVED INCOMPLETE due to lack of response to last question. If you feel this change was made in error, please respond to this bug with your reasons why.

Yes, I am still experiencing this issue with the current version of TB (10.0.2). Based on Aureliano's comment it is apparent that these are deliberate behaviors. In my opinion, expanding the groups should be possible from clicking anywhere on the header row but that would ultimately be a Wish List item though. However, he did mention that double clicking on the collapsed group should open up the messages in new tabs or windows based on your preferences. In my case, the new windows open up but the messages are not displayed. Is that the desired behavior as well?

Blake, what do you think? Current behavior may be intentional but I think this change would be useful. Double click on folders expands a list of subfolders. And this request seem analogous (except that double clicking threads will not work)

The current behavior is all over the map, depending on whether it's a mail, feed, or news folder and also whether the dummy header is expanded/collapsed at the time and then on how mail.operate_on_msgs_in_collapsed_threads is set. Opening implied multiselect messages sometimes works sometimes opens empty tabs. This patch will make a click anywhere in the header (cyclers too) select the row, and make a double click anywhere toggle expand/collapse. An <enter> will also toggle.
