It seems opening version.html in a tab slows down or hangs Thunderbird for some users.
This happens occasionally when QuickFilters ads are loaded into a new tab in Thunderbird. The tab shows "Loading" and the condition locks all other function in Thunderbird. I am unable to exit Thunderbird and must use Task Manger to end the task. The problem does NOT affect any other function within Thunderbird that I can detect. When I restart Thunderbird the "ad tab" is not shown and full function is restored.
Thunderbird version 102.9.1 (64-bit)
Windows 10 Pro Version 10.0.19045
