The bar immediately above the text area where one changes fonts, sizes, colors, italics, underline etc. in Thunderbird is missing. How can I restore it?
which version of Thunderbird are you running?
I just upgraded to Thunderbird 5, so that's what I will refer to.
When you compose an email, you can launch the 'Formatting Bar' by going to > View and putting a checkmark next to 'Formatting Bar'. This is the > View menu in the window for your new email, not the main Thunderbird window.
Please let us know whether this worked for you. Thanks!
