Hello. I have been having an ongoing battle with Mozilla Thunderbird on a Windows 10 computer. Thunderbird turns into a frozen email client with this error message : Warning: Unresponsive script A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete. Script: chrome://messenger/content/folderpane.js:2221 I tried looking up that exact error message, but I cannot find any instance of it. I have already unsuccessfully tried moving and deleting emails, as some other users have done for a similar error message. I am now trying to run it with add ons disabled. Would anyone have a fix worked out for this? I would appreciate the help!
