What's your computer system and Firefox version?
Is this with all web sites, some, a few?
Could be that you have CR/LF (\r\n; %0d%0a) as line ending and that both these characters act a a line break.
Maybe use a text editor that can set the line ending to LF (\n; %0a) only.
Do you mean even the simple boring text boxes on this forum, or fancier rich text editors on email sites, for example? If it happens even on this forum, I would suspect some incompatibility between your keyboard software and Firefox.
One workaround may be to use Shift+Enter, which traditionally creates a new line without creating a new paragraph.
