What happened with text font size in Thunderbird 115.3.0?

I've been using Thunderbird for years, but the latest update is terrible! The message list is almost unreadable, and there's no way to change the font, or at least increase the reading size of the list!. Space between lines is non existing, Font size is small, no zoom option... overall, your worst update ever! After this update, and if nothing changes very quickly, I definitely will opt for other email client than yours.

Font settings before under preferences no longer seem to work. What does work and to me is an improvement is that the font settings are now under the View menu. You can reduce, increase size to whatever you want.

Those settings no longer work for me.   I am stuck in the tiny default size.  V. 115.50  Windows 11

This new configuration needs to revert back to the previous version. No matter what adjustments are made to font size, etc., it is not as appealing or legible as the previous version.

Playing around with view / density, zoom, font size, I got back to almost normal (see very thin photo below):
edit: plus I used the Mozilla 'light' theme, which helped a lot as it used a different font style.

And why did they move the menus around?  File, Edit, etc. is _always_ at the top placing other menu bars close to the work area.  Change for the sake of change confuses long time users and makes us look at other solutions.  Very, very unhappy to have to now spend time trying to get the UI back into something I can just use, without relearning where everything is.

I agree, even with the change in density / font size. I believe the contrasts/color/fonts have been changed (To be more "smooth" ?) and after only half an hour, I have an headache trying to focus on the screen

and there's no way to change the font

I keep finding people saying things like that and I have no idea why.

The Supernova 115* has more user friendly methods to control the Font Size than ever before.

On 'Menu Bar' toobar - View > Font Size > increase font size/decrease font size

On 'Unified Toolbar' use the 3 line 'Menu app' icon - click on it to see 'Font size' - you do not even need to locate it - it's on the opening menu list - where it tells you the currently used size in pixels and offers + and - icons to increase/decrease the font size.

The 'View' > 'Density' controls the space in between items and there are 3 options.

The Message Pane itself if using same default size can alos be influenced by the same Font Size controls, BUT people tend to put html code into emails in an attempt to control the design. In Thunderbird this can also be very much controlled and often people like this area a little larger in font size than used elsewhere.

Some people just use the Zoom - let's be very clear on this - Zoom only effects the Message Pane - the contents of an opened email - Zoom does not effect other areas like 'Folder Pane'.

However, if you end up using the Zoom a lot then it means you should set up something more suitable to prevent all that unnecessary zooming.

  • Settings > General
  • scroll to 'Language & Appearance'
  • click on 'Advanced'
  • Select 'Fonts for:' and choose 'Latin'
  • Set all Font Size a bit larger than you are using for the Folder Pane & Thread Pane eg: 16px
  • Set the 'minimum size' a bit smaller, so it stops people from forcing tiny font eg: 12px
  • Then select 'Font For:' and choose 'Other Writing Systems' (bottom of list)
  • set identical font sizes as the 'Latin'.
  • If you want more control over fonts then uncheck 'Allow messages to use other fonts'
  • Click on OK

The above sets up settings for both western and unicode, so do make sure you set up for both 'Latin' and 'Other Writing Systems' and indeed any other language format you use eg: Cyrillic

2 computers here with the same Thunderbird version (115.5.1), and on one everything works fine when managing font size, and on the other one it is a mess.

The main difference is for the one having issues the screen size is 3440x1440, when the other one is only 1920x1080.

Could it be related?

Yes.  Screen size 3440 x 1440.  Is this one of those ultra wide screen monitors? Some MAC computers run those pixel sizes and often are using something they call duel retina or scale of eg: 125%  basically a type of zoom, so it renders a sharper image.  Thunderbird uses pixels for font size not points. So on each screen a 'pixel' will be a certain size. It means a 12px on one screen can look larger than on the other, due to individual pixel size.

You may also discover the font choice in 'Language & Appearance' settings can effect the general UI font size controls. It generally is not an issue, but in a particular MAC in another Support forum I've been trying to find out why inceasing Font Size does not effect eg: Folder Pane and it looks like there is a setting in Languages & Appearance which seems to block the font size.

The compose text is too tiny regardless of font or text size you choose. I have to choose HUGE for it to look like medium. But when I send it, the recipient receives it as huge. TB 115.5.1 has become virtually unusable for me at this stage. Will try to find backup of a pre-100 version and set it to never, ever update.

In 'Settings > Composition'

You should select: Variable Font and Size Medium so that it always renders as whatever the recipient uses as 'medium'.  

But when it comes to you composing messages, the 'Medium' is determined by whatever you have set up as medium in 'Settings > General > Language & Appearance > Advanced'.

The 'Proportional - Sans Serif - Size: eg: 16 = medium for you.

But you must set up 'Fonts for' 'Latin' and ''Other Writing Systems' because 'Latin deal with western encoding and 'Other Writing Systems' deals with unicode encoding'.

The advise I have previously offered basically tells people what they need to check. However, people seems to mess up all sorts of things and it all goes out of ballance. Many times people set minimum sizes which are so large they override all their normal settings.

I cannot offer advise on what to do specifically in your case until you state exactly what settings you are using.  In Help > Troubleshooting Information, scroll down to 'Important Modified Preferences' and look for lines that start with 'font.' Copy all those 'font' lines and paste it into a comment, then I'll know what you are using.

Am using the latest portable version of TB. Odd thing is that it works perfectly fine on another computer (windows 10, 2560x1440p display). On main PC (4k display) and dual booting Win 10 and 11,  text, view is large in Win 11 but tiny on Win 10, esp when composing.

Am thinking nothing wrong with TB itself, just odd scaling behavior on high res displays.

This is because the scaling effects the pixel size itself, so a size 12 can look much smaller on a high res display. When using a high res display please check this via the Menu app icon (3 lines) Font Size = 12px ? 

If the computer is forcing smaller size pixels then this setting may be too small and if it gets down to something like 7px then it may be difficult to increase that size - therefore do this -

  • Settings > General
  • scroll to bottom and click on 'Config Editor'
  • in search type: uifont
  • look for : mail.uifontsize
  • click on pencil icon to get edit mode
  • remove the low number and type in 12
  • click on tick icon to save

This should get a better setting in Font Size and make it operational again. It has worked for those people have reported a much smaller size eg: 7px and they cannot increase it by clicking on the small + icon.

i would like to share with the dev a small bug in thunderbird about shortcuts in mail window.

so, every time i read my mail it is impossible to use the zoom shortcuts CTRL-/+  the directly.

i must first to play with the size font icone and after that i can use the shortcuts to zoom in the the mail.

It's really painfull because thunderbird has a bad managment font size in raw text: regardless of the settings i can use, the raw text font size are always small.

this bug is still there even after an update version or a OS changing (manjaro-ubuntu)

Version: thunderbird 115.7.0

OS: endeavoursos (archlinux)

regards

Almost afraid to use TB in business correspondence. I reply to a mail and the first part of the sentence is the normal font I would use, but mid-sentence it changes to a tiny font that looks silly and unprofessional. And I only know that when viewing it in the sent folder. No warning whatsoever that this is the way it will look. How about an option to see how the composition will actually look before mail is sent?

Not entirely sure what occured but here is some info:

When you compose, text can get altered if you use 'paste' because when you 'copy' text you are also copying formatting, so it's best to use 'Edit' > 'Paste with formatting' so only the text is pasted and the formatting follows whatever you have selected in Thunderbird. 

I also notice you mention 'Reply'.  This means any formatting the sender included in their email to you is now also included in the 'Write' reply email which you now want to type. This can influence the formatting of whatever you type depending upon the html css in email. 

There are ways to get around this - when you click on reply to open new Write and it includes the email you are replying to - use Ctrl+A to highlight everything and then select 'Format' > 'Remove all text styles', so that you can apply eg: Variable width' to everything.

To check what you send before sending there are a couple of options:

  1. Save as a draft, select 'Drafts' folder and select email to see content.
  2. use 'File' > 'Send Later' which puts email already prepared for sending in the 'Outbox' which is located in the 'Local Folders' account. Select email to read. If it looks wrong - right clickon email and select 'Edit as new message'. This means you do not lose all the content and can use the Ctrl+A to remove formatting and reset. You can then delete the 'wrong' email in Outbox'.
