Thunderbird delete messages very slow | News-Feeds

[Hachel]

Version: 140.11.1esr (64-bit)

Since the last update, Thunderbird has been deleting individual messages from the “News Feeds” folder very, very slowly.
Sometimes it takes up to a second. Deleted messages are stored in a local folder
and this folder is only completely emptied after Thunderbird is closed.

Is there a solution for this?

Best regards,
Steven
