Status: RESOLVED DUPLICATE of bug 1785812

(Thunderbird :: Message Reader UI, defect)

Description

[carodri2]

Attachment: paint-error.jpg

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.102 Safari/537.36

Steps to reproduce:

Open Thunderbird

Actual results:

Initial window opens and does not complete display of the UI with all folders and messages. See attachment.

Expected results:

After the initial window appears and a brief period, the rest of the UI should come up.

This started happening with the 08/18/22 release; the 08/17/22 release does not have this issue.

Yes, I had seen that as well. 😳
But I can't say exactly how I got rid of the bug.

The error log was full of messages like: "can't access 'textContent'..." or something like that. @Reporter: if you see these messages too, please copy one here.

Troubleshoot Mode had helped - but disabling AddOns was not sufficient.

Next I tried:

• "More Troubleshooting Information" -> "Clear startup cache"
• Restart Thunderbird
  But that didn't seem to help.

Next I opened the context menu of the Toolbar and activated:

• Customize -> Restore Default Set
• Restart Thunderbird
  Didn't help either.

Next I opened the Customize Toolbar dialog again and switched the options: "Title Bar"/"Drag Space" and Icon setting.
With success! After a final restart, I got my content back.

Switching again does not bring the error back. So I don't know what helped.

@Reporter: Maybe you can try my steps in reverse order. We might find out what helps that way.
