Thunderbird Support Forum

I am running Supernova version 115.5.2 and have a strange situation (maybe it's normal) when opening it.

If I have received any emails for any account in a previous session, then when I open a new session, the folders for these accounts open expanded and other accounts that did not receive any emails, remain collapsed.

I know there are others who have various issues regarding all folders expanded or collapsed but in Thunderbird before Supernova, I always collapsed all my folders and opened a new session with everything collapsed.

So can anyone tell me how to set-up Supernova so that when I collapse all my folders at the end of a session, a new session will open with all the folders still collapsed?

Thanks.

Hello. Some time ago, empty folders appeared in the side panel of my account, I cannot delete them - how to delete them. Attached is an image with selected folders.

Could not find anything in add-ons, settings, or about:config. There is a topic on this site https://support.mozilla.org/en-US/questions/1086884 but I am not able to follow it because there is no add-on or plugin to enable or I cannot find it.

I am now using Outlook (imap). When I try to permanently delete a bunch of emails it deletes them and then I get a synchronizing inbox bar and the 1,000 or so emails come right back into my inbox. How do I avoid this if I am using Thunderbird?

Example: Have 9600 emails delete 2500 and notifies me that they will be permanently deleted but they never are. They just return a few minutes later. Thanks

how do I change the "from" and "subject" font appearance in thunderbird inbox list view? They are currently a little bizzare with the sender appearing smaller than the subject line etc. I am not familliar with .css file settings and so will need to be considered a simpleton with any explanations. Any aswers I have seen refer to fire fox and assume that I know how to create the changes required or add a .css file somewhere. Thanks in advance. I attach a screen shot of my current inbox view . Hope this explains my problem.
