Icon unreadable on light theme

[crystalfp]

Could the icon be more dark? With a light theme is invisible.

Thanks! mario

That is strange. The icon actually is black for the default (light) theme:

There's even special handling of icons for light/dark themes defined in the manifest:

"theme_icons": [
    {
      "dark": "/_images/signatureswitch-64px-white.png",
      "light": "/_images/signatureswitch-64px-black.png",
      "size": 64
    },
    {
      "dark": "/_images/signatureswitch-32px-white.png",
      "light": "/_images/signatureswitch-32px-black.png",
      "size": 32
    },
    {
      "dark": "/_images/signatureswitch-16px-white.png",
      "light": "/_images/signatureswitch-16px-black.png",
      "size": 16
    }
  ]

I'll need more info about your installation/settings to figure this out.

These are the theme loaded and the one selected: If I switch to the default theme, the icon reappears in black. Seems like this "light" theme (from Mozilla) is somehow not recognized. Thunderbird 78.3.2 Anyway, switching to default theme seems that does not change anything compared to the "light" one. I solve the problem this way. Thanks! mario

OK... you may report this finding in the official Thunderbird bugtracker. Thanks.

No worries. I already replied and created another bug. ;-) Thanks, @crystalfp !
