Problem when i press "ENTER"
When I write an email and want to press Enter to jump down "ONE" line, and start a new sentence, it jumps down an extra line so it becomes a space. If I instead write all the time without pressing ENTER, it jumps down one line as usual and the text becomes coherent and nice.
I can't find a setting to avoid the problem of it jumping down double lines when ENTER is pressed.

Are you composing in HTML? If so, then: At the top right of the Thunderbird window, click the menu button ≡ > Settings > Composition > HTML Style Uncheck "Use Paragraph format instead of Body text by default"
This is how I fixed it.
Go to Tools > Settings, then scroll all the way to the bottom and click on Config Editor. Type paragraph in the search line. You will see a line = mail.compose.default_to_paragraph This is NOT what you want, so, over to the right click on the two arrows (top/bottom) to turn this to False Now it will work for you.
