Every time I start Thunderbird I get the following error:

Warning: Unresponsive script

Script: chome://messenger/content/mailWindows.js171

I check Stop script and Don't ask me again, but it comes up every time start Thunderbird. This is a clean installation. Screens attached.

McAfee has a long reputation for hangs, slow performance and general instability. See https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#McAfee for workarounds and notes on McAfee.
