Current Thunderbird v38.2.0 (although problem existed in at least one previous version). Thunderbird startup is very slow (four [4] minutes) before opening the mail accounts. Error message

"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/mailWindow.js:177"

appears upon completion. Closing the error message (any way) restores normal operation and speed. Thank you for your help!

To diagnose problems with Thunderbird, try one of the following:

  • Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
  • Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 8, Windows 7, Windows Vista, Windows XP, OSX
If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.

You could also include troubleshooting information in your next answer.

To find the Troubleshooting information:

  • Open Help (or click on three-line-icon and select Help)
  • Choose Troubleshooting Information
  • Use the button Copy to clipboard to select all. Do not check box "Include account names"!
  • Paste this in your post.
