In Thunderbird, mails from the holiday rental site Abritel or its UK equivalent Homeway display terribly; they have little depth but stretch out horizontally to a crazy extent. Inspecting the message source suggests that there may be some complex use of HTML tables here. The two images without a photo show what the message looks like. I tried starting in safe mode to disable extensions but that did not fix the problem. The emails display perfectly well on my phone (Aquamail on Android) and in the webmail client of my mail service provider (see the image with the picture). I have Thunderbird 68.2.2 on Windows 10. I have tried to contact Homeaway about this, but I wonder if anyone might have any ideas here. Thanks.
