Hi,

I'm using Thunderbird 115.0, MacOS Venture 13.4.1 on a MacBook Pro (Apple M2 Pro).

I downloaded your manifest.json, created an xpi and installed it into Thuinderbird, but didn't get the full effect that I can see in your screenshots. As you will see below, while the sidebar with Inbox etc changed to solarized much of the rest has kept my previous dark settings:

I cropped this image to avoid having to smudge people's info, but I think this show what I'm talking about.

Cheers,
Ron.

I currently have Thunderbird version 102.13 installed, which is quite outdated compared to the newer 115.0 version you mentioned.

Moreover, I came across some information on the internet stating that Thunderbird is collaborating with the team behind the popular K-9 Android email app to create a fusion of both platforms. This indicates that there might be significant changes in future versions, potentially breaking compatibility with older versions. It's a bit disheartening to hear about this possible 'fatal' break with the past. 😞

Thanks for the reply. I might have a play locally and see if I can get any of those other blocks changed. When I've got some time, of course.

I've been messing about a bit with userChrome.css and I think it should be possible to theme the rest of the UI (albeit in a much more fragile way that will likely break between updates unfortunately). I'm going to poke at it a bit more, but here's what I have so far:

userChrome.css:

#spacesToolbar {
    background-color: #001f28 !important;
}

#threadTree {
    background-color: #002b36 !important;
}

table[is="tree-view-table"] {
    background-color: #002b36 !important;
}

th[is="tree-view-table-header-cell"] {
    background-color: #002b36 !important;
}
