1904211 - Exiting Thunderbird during startup causes any message tab that didn't load to be blank in future sessions

Status: UNCONFIRMED

(Thunderbird :: Toolbars and Tabs, defect)

Description

[Barry Abel]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36

Steps to reproduce:

I started Thunderbird, then hit ctrl-q after the message tabs appeared but before all their titles appeared. This caused Thunderbird to exit. I then restarted Thunderbird.

Discovered using Thunderbird 115.12.1 (64-bit) in Manjaro Xfce.

Actual results:

Any tabs whose titles hadn't appeared before hitting ctrl-q were now blank - title and content.

Expected results:

The state of the message tabs should be preserved regardless of when the program exits.

I haven't tested this using other ways of exiting Thunderbird.

This is serious because it involves a loss of information - the messages that the user considered important enough to leave open. Also, it's unfortunately a realistic scenario; it happened when I was trying to figure out why Thunderbird had just unexpectedly closed, which is probably that I had accidentally hit ctrl-q instead of ctrl-w.

I don't know whether it matters, but I had dozens of tabs open when this happened.
