Thunderbird Community Forum

I have my OS (F43 Budgie) and Thunderbird in dark mode. When I click reply to an email I get black text on a dark background.

Question number one: what will the recipient see exactly? Question number two: how do I setup Thunderbird so that I can read the reply I'm typing?

For as far back as I can remember I've been using Mozilla Thunderbird on a old computer running Windows 7. I've a Win10 machine here so a few months ago, I downloaded the latest Thunderbird and I was suprised to see it looked very different. After a bit of experimenting I managed to get it looking familiar so I uninstalled it with the intention of trying it again early in 2026 when I've a bit more free time, So this morning I installed the latest version but it looks even more different now :-(

I'm not sure how to attach images here but if it works, the original one looked like Capture01 and this morning's one is like Capture02. I still had my installer from a few months ago so I installed that one and it looks the same as today's one. Notice that there's no menu bar any more and AFAICT I can only view email headers and not their contents. Also, the 3 boxes at the top RHS (for sizing the window / minimizing it etc) don't work at all.

Is it me doing something wrong - or are there maybe some settings somewhere that I need to experiment with?

I use a work email server outsourced to office365.com and Thunderbird v115.18.0 (64-bit).

I connect using Thunderbird with IMAP, and am subscribed to 100s of my folders there.

I reorganized my folders there, moving them about using THUNDERBIRD (not, as I've learned now, using the Outlook Web interface that I "should" have used). Needless to say, I was only moving subscribed folders about.

Now I find that the subscriptions to folders which have been moved or even deleted cannot be manipulated. Folders with the same name but now in different hierarchies can't be subscribed to.

I have removed the account, recreated it and Unsubscribed from EVERY FOLDER. But the erroneous subscriptions do not go away.

I have a laptop that updated itself and is now updated to the latest version of Thunderbird. Desktop computer is still on v.115. I have the Local Folders on the laptop set to use a shared folder on the desktop and locally store incoming emails on the laptop. I use the shared folder for archiving emails on the desktop. So LaptopMail is stored on D:\LocalMail on the laptop and the Local Folders is set to store files on the desktop through the private local network on a shared folder (D:\Mail-Common on the desktop hard drive) Up until today this worked almost flawlessly. When things do go sideways on an update (which happens with thunderbird more than I like) I ususally search for an answer first. Normally, I find an answer that works.

The problem is exactly as was in this post [ https://support.mozilla.org/en-US/questions/1512216#search ] The fix however didn't work for me. I cannot directly edit the Local Directory path either. The browse button still works though. Currently, D:\Mail-Common is mapped to the "N:" drive and all that is in the Local Directory path in the Local Folders settings is N:

Any more suggestions are more than welcome
