Thunderbird-Hilfeforum

In the previous version, there was a search box on the toolbar. After the upgrade, it disappeared. How can I restore it?

I tried to customize toolbar but there is no search box in the window of available controls.

Is Thunderbird ever going to fix the 'custom colours'? After the last major update, TB would not longer hold any custom colours. This is problematic because the colours offered are either too light or too dark to be read easily.
