Thunderbird Support Forum

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

In Thunderbird 115.3.1, when I click on the Hamburger menu (3 horizontal lines), there is a "Font Size" option, but it does not do anything. Clicking + or - or trying to type in new font size - nothing works. Why?

The upgrade 115.3.1 (32-bit) is unsatisfactory to many people. For me, the worst part is the superhuge message display. I can't seem to be able to reduce the size/font of the displayed message. Other people seem to have the same problem on your "help" site. This kind of display makes it impossible to skim a major part of a message before deciding whether to open it or not. Can you please tell me if this can be fixed and/or if I can get back to the prior version of Thunderbird? I support Mozilla and Thunderbird, but this is the first time I'm really disappointed by an update. Sincerely, Jane [removed phone# and email from public support forum]

Following an automatic update the other day, everything in Thunderbird is oversized. There are in fact some things I can no longer see at all! The program has become very difficult to us to read/write emails. See the image below, a full-screen capture showing the problem . There must be a line to edit in the fonfig file to make the display look normal again. Please help me find that line!! I am visually impaired, and life is difficult enough already! tnx, Paul pgschreier@swissonline.ch

I tried to change the size of the text in Thunderbird and now my entire mail display takes up less than a quarter of an inch of display. I tried uninstalling and reinstalling it, and it is still the same. Is there a way to get rid of those settings and go back to the defaults without doing it inside the program? I have enclosed a screenshot of it. I love my Thunderbird and am lost without it. Please help. Someone. Anyone.

I have been using Thunderbird for years. I loved it and there was never a problem. Until I updated to the latest version. My Operating system is Windows 10. The problem: It was impossible to set the size of the letters in a satisfying way. Only massive letters in writing emails resulted in a readable format on the receiving end. I tried one of the suggestions I found on the internet. Something like "set the same format initially and then again in Latin and the bottom choice of letter types". It did not work for me. So I decided to quit Thunderbird and start working with Gmail. Which is okay, but you have to be online and you have to change websites if you use more than one email address. I don't expect you to have a solution, but I want to inform you that I decided to quit after a years long good experience. Thank you for all your work and effort, Daniel van Schooneveld

how do I increase font size of incoming mail in Thunderbird version 115.4.2 64 bit? I have tried all solutions on your site and nothing happens. Changing the value of font settings makes no difference. The value doesn't change.

I just upgraded to 115 and now Thunderbird is not usable any more. I have a HiDPI 4K screen, KDE Plasma and Wayland. Everything in Thunderbird is HUGE! It cannot be used. All other apps, including Firefox scales right, without issues. What can I do?

The Thunderbird Inbox is a mess..... Everything has lots of room, except the actual message. Mine is about 1" tall! How can I either fix the problem or go back to the previous version? Please bear in mind that I am not a very good problem solver, so I will need a step-by-step solution. Thank you.
