Thunderbird Community Forum

I have set a custom theme on my Thunderbird on Linux. As you can see by the attached image though, the menu bar is hard to read when you get to the right side. Dark background and dark text doesn't really go together. Is there a way to make the background of the menu bars a solid color or something less see-through so the text can be read? I want a light theme, but I need to be able to read the menu.

Hi I am a theme girl and have tried many over time. I had never used the Dynamic Theme which is supposed to change from day to night along with what it's doing outside. It was kind of bland (sorry to the creator) so I tried to change it to another one and it worked just fine. When I came back to my computer it had changed back to the Dynamic one again. Again I changed it then it was back again. Yesterday I actually removed it from my list of addons and now it's back again. How do I stop it? Thanks for any help. ♥

Thanks

Moderator note: Moved to the Thunderbird Desktop forum from the Firefox Desktop forum.

As per my title, where can I find a themes toolbar background image and change it? I have tried looking for manifest.json and header.png files for the theme but I can't find it.

Or is there a way I can override it using CSS somewhere?

Does anyone else have the issue where the interface just looks bad? It's like I'm using an old version of Microsoft office on a Windows 3.1 machine. I see in the settings I can change the font sizes for composing emails but how about the system interface? Others say "just download a theme" but could someone recommend one? This current font makes me want to delete this software and look for alternatives. I only checked out this software because Microsoft sucks. And I'm about ready to leave this one also.

Greetings!

I downloaded a theme that I really like for Thunderbird, but I would like to ask for your help. I would like to change part of the frame to a different color (similar to the one on the left), but I don't know how to do it. I am attaching a photo where I have circled the part I would like to change with red lines.

Thanks for your answers!

My question: is there a way to force a light TB theme and use white tab background text color?

I installed a theme add-on which I like except the associated dark theme. I want to use the theme image with a light TB theme but it appears the tab background text color determines the theme color (light or dark). This image has some darker colors and a light/white tab text looks the best, but this color seems to force a dark theme for the rest of TB (White text ->dark theme). If I change the manifest file to use a different tab background text color I can change the overall theme to light or dark. Using a darker or black tab background text color the theme changes to a light theme. Light tab background text color changes to a dark theme and darker tab background text colors forces a light them. I'm guessing there is a threshold 1/2 way between black and white text that will force the theme one way or another.

The articles I have read on this json file don't provide any examples and this is as far as I have been able to get. I'm new to both TB and modifying this json file. Any help would be appreciated

I am trying to change my Theme and every time I enable a new theme, it changes for a minute but then it reverts back to the old theme that I can't even find anywhere in Thunderbird or on my computer. How do I get the new theme to "stick"?

Hello Mozilla Team,

I would like to request your assistance with an issue regarding complete themes on thunderbird.

The issue here is that I simply cannot install any of them, no matter which one. I've checked multiple and they all display "This add-on is not compatible with your version of Thunderbird. " I am running Thunderbird 128.7.0esr.

I am able to download the normal themes and other add-ons just fine, but I was really looking forward to complete themes.

My PC specs:

Ryzen 5 3600 GTX 1660 SUPER 6GB 16GB RAM SSD 500GB

Windows version 22H2 19045.4170

I hope you are able to assist me on fixing this issue.

Thanks.
