On my wife's computer, when she starts Thunderbird, it freezes for 3-8 minutes, and then she gets an unresponsive script error message. The script listed is "script:Chrome://messenger/content/toolbarColor.js:48" If I cancel the script, Thunderbird works so long as it is not closed and restarted. This just started in the past couple of days. I HAVE tried to uninstall and then reinstall Thunderbird, but that had no effect on the issue. She has the latest version of Thunderbird installed, and is using Windows 10 Home.
