Thunderbird Support Forum

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

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?

Hi, I got the (unwanted) Update on Thunderbird 115.2.2 (64-Bit).

I use a notebook 14" with full HD. With the new update I have trouble reading the texts in Thunderbird, mail, etc. because of the font size & layout. I wear glasses and I'm 50+ ......

HOW CAN I GET BACK THE OLD LAYOUT AND TEXT SIZE ??

I'm really pissed :(

Thanks, Martin

This is the second problem I have discovered with the latest TB update. Now, my unified folders are not fully populating. For instance, the unified inbox and sent folders are missing a number of messages that can only be accessed through the individual folders. In the case of the unified inbox, it will indicate that new message(s) have been received, but they are only listed in the individual folders. This new update also messed up my unified folder preferences for the appearance of columns, and frankly, I also don't like the new user interface look. If it's not broke, don't fix it.

Thunderbird updated on its own without notice to version 115. When I tried to open Thunderbird, I received login errors for each account and all my messages were missing. I tried uninstalling it and reinstalling version 102 and now it says that my profile is incompatible. My POP account and local messages are all gone. I don't want version 115. It is clearly incompatible with my computer and accounts.

I'm having an issue that's related to 115 as I didn't have this problem on 102. This is also not related to gmail, live.com, icloud or other exchange accounts, only my IMAP accounts are having this problem. I have it set to a unified folder and I display both sent and inbox in the thread. Some of the items in the inbox show twice and some, if not most of the items in the sent folder on the thread show twice as well.

I now have two issues, one is that on my IMAP accounts with my own domain, both the recent sent and recent received emails in a thread are showing up twice. This doesn't happen with previous emails in that thread or with gmail, exchange, outlook.com, live.com, icloud, etc.... Now, I have an issue where the pop ups for calendar notifications keep popping up non stop and either won't go away by hitting "Submit to changes anyway" or if they do go away, they immediately pop back up again. 115 is a big disapointment for me, it's been highly glitchy, many add ons no longer, some that should work, don't work properly, it was hyped a major upgrade and I see very little that distinguishes if from 102 in any meaningful way except some of the icons are more colorful. Is there a way to go back to 102? Either that or I may start using Mac Mail again due to all these bugs.

TB seems to have updated itself this morning so when I just started it, the mailboxes under Inbox are all reordered, and some of my mailboxes have vanished - not even there. The domains of the ones that vanished are not mainstream ones, they are kinzelman.com and medflightair.com

Under Tools | Accounts, the accounts are still there, how do I get to these vanished mailboxes? How did the update vanish them?

In the accounts I don't see any 'hide inbox' or anything to cause them to be invisible.

I became excited about the hype. I downloaded 115 and ran it. Two things I immediately noticed, one is the icon is different, and the other is that the UI looks almost exactly, but not quite, like the old UI. Not that this is bad, I use TB everyday on my Mac and it is my email client. But first impressions were underwhelming especially after the hype. One thing I noticed that's an improvement is that TB now recognized my Mac address book so I no longer need Card Book. Other than that it's much ado about nothing.

How many problems have I had with TB 115, let me count the ways:

• Subscribed calendars won't display on 115, they work on 102
• Sent and received emails from my imap with my domain are duplicated and drive me crazy and nobody seems to be able to fix it despite my long string of communications with you all, works fine on 102
• Non related emails thread together in 115, work fine in 102
• Many add ons that I use and relay on, in 102 do not work on 115

I just reinstalled my OS from a Time Machine Backup in June. I have my cherished 102 back. I will not update for 6-12 months until you all work out the problems with 115. I'm not a Beta tester, I'm a paying user and I resent the poor quality and lack of effort on several of my problems. I never heard back from you all regarding the subscribed calendars that I can install in 115 but don't display. I never heard back from you all regarding emails appearing in the wrong threads. I did hear back from you all on the duplicates, and for a long time, I could tell you thought it was user error. Then you acknowledged that I knew what I was doing and you tried some fixes but seem to have given up as I haven't heard back for days. This is poor customer service and again, I'm a paying user.

Let me know when you work out your problems. But 115 should never have been released as it's barely a Beta product and it offers little upgrade in terms of appearance and a very large downgrade on usability.

Hi. This release is buggy and the new UI is very small (and if you enlarge it the entire layout is affected).

By 'buggy' I mean there is a lag when I delete a message from the inbox, and instead of the other messages moving up to replace the deleted one, the deleted email appears twice. And when I delete multiple messages in succession, the lag causes other messages to be deleted unintentionally.

How to revert to the previous version?

Thanks!

115.3.1 (32-bit) automatically upgraded on Win 11 PC.

Thunderbird mail header rearranged / disappeared and I am unable to get Menu Bar above Custom toolbar?

When I right click on an email in the right pane, I no longer have the option to "Save As" HTML or PDF. Other Save As options are also missing.

Is there a way to restore these features or go back to the previous version of Thunderbird?

Hi, I just got the update to Supernova 115.1 (from 114), and it's clear you guys have been doing a lot of work. Thanks. There are two issues I can't figure out from the UI or the docs:

1. The standard text-only toolbar (File...Edit...View...Go...Events and Tasks...Tools...Help) is not at the top of the toolbar stack, where it should be...instead, it's below the tab-specific toolbar. I can't seem to change the stacking order.
2. The font vertical separation in all of the main email panes is too small, and appears to be un-adjustable. This makes the email box view and the email list view much harder to read than before. Perhaps there's a setting for this in the about:config world?

I know zero about technology but all of a sudden my email changed and I didn't like it and I fiddled around with it and now I have no email at all. I am 81 and don't know tech language but I need help please. I just want my email back the way it has been for 20 years. Thank you.

Thunderbird seems to pick some emails and identify them as toxic and permanently deletes them before I even get a chance to see them. Not in Spam, not in Trash, just completely gone. Gone from the gmail server as well. I have lost two very important emails this way and I need to stop it.

Hello,

a few days ago I switched to the new version 115 and I find it very nice. In my daily work, I use View > Folders > Unread Folders most often.

If I now open unread mails in a folder, the folder is actually no longer an "unread folder". In the "old" version of Thunderbird, folders were refreshed at irregular intervals and folders were automatically hidden when there were no more new mails to read.

This no longer happens with 115. Here the read folders remain visible all day or until I manually select View > Folders > Unread Folders again.

I would therefore be very pleased if this old function were possible again.

Thank you and best regards from Berlin Florian

What on earth have you done on this 'SuperNova' Update?

The Thread Pane is pointlessly large. I used to adjust this to about three lines of emails - now the minimum setting is about TEN lines. I cannot read my emails! They are left taking up about an inch of the screen!

I tried the vertical layout and while I can read the emails better, a huge chunk of the screen is pointlessly taken up with the list - and it's still far too wide.

I found one ridiculously complex 'workaround' which more of less meant writing code - no thanks!

Please sort this now

The very top of the window has Get Messages Write Delete Junk etc. I don't want these there. I use that part of the window to drag it around my screen. I only need some of those features when I'm in an actual message like reply, reply all, etc. Why are they up there?

How to I customize that top bar. And actually I like the old way of the File Edit View being on the top.

This new version is so much worse than the previous one. I see no advantage to any of it. How do I get the old one back.
