Thunderbird Community Forum

This seems to have occurred in the last month or so.

Whenever I click on a message in the folders pane, the message is not displayed correctly in any of the three layout views but, if I am offered to display in a browser, it does! Also, if I select 'Edit as a new message' it displays correctly, as also do iPhone and iPads. The screenshot shows the problem?

Any ideas, anyone?

Thunderbird (153.4.0esr (64-bit) ) does not display or let the user change its printer setting before launching print preview from the print command. If Thunderbird is set to choose a missing printer, it gets stuck trying to contact the missing device in order to prepare a print preview. It seems to be stuck forever, it does not seem to time out. There is no cancel button. If you close the document tab, you can permanently lose the document if it is a draft email, unless the email service saves it in a trash folder. The printer setting can be cleared if the user manages to learn how to display and clear the troubleshooting information.

Thunderbird needs to display the printer setting and permit the user to change it before launching the print preview operation. It needs to display a cancel button during the print preview operation.

Lately, Thunderbird has been using excessive CPU time even when idle. I am on Windows 11 and running the 153.3.1esr release of Thunderbird. It's impacting other applications. When I exit Thunderbird, everything runs faster. Right now it's using over 7% CPU and about 500 MB of ram.

Hardware is HP Pavilion Desktop 590-p0xxx. Intel i5-8400 2.8 GHz 12 GB ram.
