Reproducible: Always Steps to Reproduce: 1. Edit->Preferences->Main 2. check 'Show the Downloads window....' AND 'Close it when all d/ls are finished' 3. close preferences 4. Download a file (while no other files are still downloading), for instance the Lightning Plugin at https://addons.mozilla.org/en-US/thunderbird/addon/2313 5. When the file finishes, a popup in the bottom right corner will say 'All files have finished downloading'--click the link Actual Results: By the time the popup appears, the DM has closed (based on the preference). Clicking the link, opens the DM for a flash second, and then it closes itself immediately again. Expected Results: Since the user explicitly has clicked to open the DM, the DM should stay open for the click (similarly to if one goes to Tools->Downloads) The behavior only occurs when both these configuration options are checked. With one or neither checked, behavior is as expected.
