Hello,

The new UI has this massive customizable toolbar at the top of the screen, it wastes a lot of space and doesn't look good compared to the old UI, you can fully customize it even leaving it blank but that does not remove it entirely and it looks off with just a blank nothing up there, where is the option to completely remove this new toolbar?

Regards,

I'd like the list of messages in a stronger font, with less white space. And distinguishing unread messages by color instead of bold.

Can any of that be configured?

I'm a Thunderbird newbie, moving from Agent where the inbox displayed twice as many message headers in the same space, but was more readable because all messages were in a bold font but the unread messages were in red.

Hi. I really like the new look of 115, but the file menu should be above the toolbar. Is there a way to put the file menu at the top of the window (above the toolbar)?

Thanks

Hi,

after updating to new Thunderbird 115.0 menu bar appeared below tool bar and I couldn't find a way how to put it above as in previous versions. Please see attached image. Any idea?

Thank you.

Since Thunderbird changed the menu bar is not any more above the email bar. It is with Bestand, Bewerken, Beeld enz.

How can I get it back at the top??

It is far less easy now.

I wanted to ask for help but on the Dutch site I could not find a button for help. Only at he English site.

But I am Dutch.

Hope that I can get the Menu bar on top again like in Firefox..

Please help and change it back.

Kind regards

I currently use:

  <profile>\chrome\userChrome.css 

to make various buttons stand out for some elderly users that I support. For example:

1. button-archive:hover {

  border: 2px dashed black !important;

}

1. button-archive,
2. hdrArchiveButton {

  background-image: none !important;
  background-color: #66ff66 !important; 

}

I can't figure out how to do this with Supernova (115+). Thanks.

I have a userChrome.css to change the color of unread messages in the "list of messages" pane to orange:

/* Messagepane text */ treechildren::-moz-tree-cell-text(new) {

       color: #34ebdc !important;
       font-weight: normal;

} treechildren::-moz-tree-cell-text(unread) {

       color: #34c6eb !important;
       font-weight: normal !important;

}

This worked fine in TB 102 and prior. When I upgraded to TB 115 this no longer has any effect. I'm not sure if the userChrome.css is being ignored or if the styling elements in userChrome.css have changed.

I'm on Windows 11 and userChrome.css is located in 2 places: C:\Users\$username\AppData\Roaming\Thunderbird\Profiles\$profile.default\chrome\userChrome.css C:\Users\$username\Application Data\Thunderbird\Profiles\$profile.default\chrome\userChrome.css

Re: userchrome.css It appears only part of my userchrome file affects customization in latest release (115). Is there any information on use of, or changes needed, to continue customizations, e.g. mail folders font weight, message pane grid lines, mail folder pane background color, thickness of pane splitters, etc.?? Everything worked in 102.x...

After upgrading to 115.0, the mailbox display has an all-white background. This is not nearly as easy to read is in version 112, which has alternating lines of white & grey for the background.

How can I customize 115 to have alternating colours for the background of each summary line?

I want the unread messages in the list of messages pane to be "orange". I had the following in userChrome.css which worked prior to TB 115:

/* Messagepane text */ treechildren::-moz-tree-cell-text(new) {

      color: #34ebdc !important;
      font-weight: normal;

} treechildren::-moz-tree-cell-text(unread) {

      color: #34c6eb !important;
      font-weight: normal !important;

}

When I upgraded to TB 115 this no longer has any effect. How do I do this in TB 115+?

Thanks. mike

Does anyone know how to change the folderpane colours in 115. I use a userChrome.css, which no longer works in 115, as I beleive the commands have changed.

This is what I use currently, but have no idea what changed need to be made to make it work in 115. Any help would be appreciated.

Hi, In TB 102 the menu toolbar was still above the button toolbar, if I am not mistaken. In TB 115 this seems to have changed... I could not find a way to customize it back as it was. Pointers anyone ? Thank you.

was recently forced to upgrade to winblows 11.. in the previous version of Thunderbird, 102.2 64 bit, I could follow these instructions to background colors in the various panes .

https://support.mozilla.org/en-US/questions/1389364

Now with version 115.0, I am having issues getting it to work.

the CSS file I am using is

1. threadTree > treechildren {

 font-size: 16pt !important;
 font-family: Times !important;
 background-color: lightgrey !important;
 color: navy !important;

}

1. folderTree > treechildren {

 font-size: 16pt !important;
 font-family: Times !important;
 background-color: lightgrey !important;
 color: navy !important;

} after I follow the instructions, carefully, nothing happens. see screenshot attached...

I have 2 questions:

1 - what am i doing wrong? 2 - In the attached screenshot, how can I get rid of that toolbar in green on the left?

Hi I find horizontal lines between messages a big help. I've updated to TB 115.0 and the lines have disappeared. I referred to the past set-up method. I've checked that the chrome.css file still exists in the correct directory and have checked toolkit.legacyUserProfileCustomizations.stylesheets is set to true. I've tried switching to false, close down, open and back to true, close down, open, without success. Can anyone please advise how to reinstate this feature? Thanks

Re: userchrome.css It appears only part of my userchrome file affects customization in latest release (115).

Q: Is there any information on how to do customizations for the following specific items: 1. message pane grid lines, 2. message row alternating colors 3. thickness of all pane splitters?

Thanks for any leads....

I used to use something like this to reduce the fontsize and remove bold from the folder items...

   #folderTree > treechildren::-moz-tree-cell-text {
     font-size: 75% !important;
     font-weight: normal !important;
   }

I've looked through this file and tried a few likely options but nothing seems to work...

https://searchfox.org/comm-esr115/source/mail/themes/shared/mail/folderPane.css

Would anyone have a suggestion as to how to convert the above snippet from the old CSS scheme to 115?

Actually, I would also like to change what is bolded in the folder pane to blue (unbold) like the next example for the message thread pane which does work in 115...

   #threadTree tbody [data-properties~="unread"] {
     color: #5FAFFF !important;
     font-weight: normal !important;
   }

Hello, I have been using a custom userChrome.css in the past, but it does not work since I upgraded to 115.0.1

Is the userChrome.css still supported? I have turned it on in config mgr, and tried every resource I cna find on the web, but my userChrome.css is ignored.

TIA...

Yesterday I tried the 115 (Supernova) and I was disappointed because of the toolbar on top of the TB window: I think that you should let the user choose where put any toolbar, and I didn't find the way to move in its "classical" place (not at top but below the menu). There is a way to do it? And if not, please consider to give it as soon as possible.
