Unlock custom CSS usage in Thunderbird

Settings/Options > Advanced > General > Config Editor...
toolkit.legacyUserProfileCustomizations.stylesheets > true

Where to find Thunderbird profile folder? The correct location for user styles.

1. Find your profile folder
Windows
C:\Users\ USERNAME \AppData\Roaming\Thunderbird\Profiles\ PROFILE FOLDER NAME \
Hidden files must be visible to see AppData folder. Alternatively open %APPDATA%\Thunderbird\Profiles\ from explorers location bar.
Linux
/home/ username /.thunderbird/ profile folder name /
Hidden files must be visible to see .mozilla folder.
Mac OS X
~\Library\Thunderbird\Profiles\ PROFILE FOLDER NAME \ or
~\Library\Application Support\Thunderbird\Profiles\ PROFILE FOLDER NAME \
\Users\ USERNAME \Library\Application\Support\Thunderbird\Profiles\

2. User styles belong into \chrome\ folder. Create it, if there is none yet. It should look like this afterwards:
\ PROFILE FOLDER NAME \chrome\

3. Copy userChrome.css, userContent.css and \config\, \css\, \images\ folders into \chrome\ folder. It should look like this afterwards:
\chrome\config\
\chrome\css\
\chrome\image\
\chrome\userChrome.css
\chrome\userContent.css

How to use custom user styles?

The userChrome.css and userContent.css files works like an options\configurations file. All main "features" can be enabled and disabled there.
Edit userChrome.css and userContent.css with any text editor (Notepad++ recommended on Windows) and enable or disable any feature you like by modifying, removing or outcommenting available @import strings.
Restart Thunderbird after every modification for changes to take effect.

Example
If "classic button appearance for navigation toolbar buttons" should be enabled, the corresponding line has to look like this:
@import "./css/buttons/ctb_on_main_toolbars.css"; /**/

If "classic button appearance for navigation toolbar buttons" should be disabled, the corresponding line has to look like this:
/* @import "./css/buttons/ctb_on_main_toolbars.css"; /**/

Note
Code between /* and */ won't be used by Thunderbird unless there are other /* or */ in-between.

How to find item ids and attributes?

Hit Ctrl+Alt+Shift+I or open 'Tools > WebDeveloper > Browser Toolbox'.

Inspect ui or web content.

Force popups to stay open for inspection: Click on 'Customize Tools and get help button' (= button with three dots) and select 'Disable popup auto-hide'.

customcssfortb's Issues

Ivent invitation support - ctb_on_main_toolbars.css

1. Describe the issue
   ctb_on_main_toolbars.css seems to lack styling for event/invitation related buttons (they use default styling when compared to other one)

2. What should have happened instead?
   All button on toolbar should have the same style

3. Steps to reproduce the issue?
   Open the message that have an event/invitation for default Lightning addon

I believe this can be fixed by addingone of the following element #imip-view-toolbox (or maybe .lightning-notification-bar) to the existing style

ThunderBird 78: ctb_on_main_toolbars - "Compose new message" window

1. Describe the issue
   After update to ThunderBird 78 some new elements were introduced to "Compose new message" window.
   They are not styled properly

2. What should have happened instead?
   I believe that new elements shod be styled the same as currently existing ones.

3. Steps to reproduce the issue?
   Open "Compose new message". Observe CC, BCC section.
   Compare it to filters of the message pane (in vanilla they share same visual style)

Spaces Toolbar handling

How To Hide Spaces Toolbar Button (Linux) 102.11.1

Account Colors Add-On

Sorry -- I couldn't find the General Discussion Area and didn't know where else to post this. Its not really an open issue.

thanks

1. Describe the issue
   There was an Add-On Extension called "Account Colors" that provided for setting different colors for users who managed multiple email accounts with Thunderbird. That Add-On stopped working after version 68 of TB and the original Developer decided not to rewrite it for the "New and Improved (?)" Thunderbird.

There have been several "suggestions" like using BorderColors (which only works in the Compose window) or setting Filter/Tags to tag each message a different color in the message pane but neither of these actually allow setting a color by Account and does nothing in the Unified Folder Tree --- the original Add-On even allowed for setting a color for the Local Folders, too.

This may be the wrong place (I did post on the TB Mozilla forum) but was wondering if there is a way to set Account Colors in a User Chrome Style Sheet for TB?

I'm not a programmer, just a frustrated user who has downgraded all my systems to Thunderbird Version 68 just to keep the original Account Color Add-On. Others have done the same and some have even switched to a different email client.

If you have the time, please take a look at the original Account Colors Add-On options and see how flexible it was.

Thanks for your time --- if CustomCSSforTb could work, please let me know.

6. System information

Removing rounded corners from the menus of thunderbird 102

1. Describe the issue
   One of the annoying changes I have noticed in tb 102 is the rounded corners that appear in menus, as seen in the screenshots below. They have that w11 look with the rounded corners, the ones that appear white do not follow the gtk theme of the desktop and when the window is inactive, the text on the main toolbar almost invisible (light grey letters on dark grey background.
   I tried your css, I played around with its options but it does not seem to solve anything of the above, so the main question here is if any of this is doable via css.

2. What should have happened instead?
   A lot, as I described above. I would be happy even if I managed to only get the right-click white menus to follow the gtk theme.

3. Steps to reproduce the issue?
   Install or upgrade to thunderbird 102 on a linux distro, prefereably on one using a dark gtk theme.

4. SCREENSHOTS with/without this projects files
   The all white right right click menu with the rounded corners

Recurring event icon TB 102

Hi,

I upgraded to TB version 102 and somehow there is an icon now in the title of repeating events.

Picture of it here: https://bug1674912.bmoattachments.org/attachment.cgi?id=9264242.

Is it possible to remove that somehow with CustomCSSforTb?

Add all information required in 1-5 and delete this line and everything above it before submitting.

1. Describe the issue
   There are some issues with ctb_on_main_toolbars.css.
   When this module is enabled some toolbars (mail, address book, calendar, tasks, etc) have different height.
   Also, toolbar button styling is not applied all the time.

2. What should have happened instead?
   All toolbar buttons should be visually the same

3. Steps to reproduce the issue?
   Enable ctb_on_main_toolbars.css. Cycle through mail, address book, calendar, tasks.
   Observe toolbar height and buttons styling

4. SCREENSHOTS with/without this projects files (drag & drop images into this post)

Mail >

• No styling for Delete, Archive buttons (multiple emails are selected)
• Toolbar height is smaller when Root folder tree item is selected (email adress preferences)
