Invisible line-breaks in text fields
Hello!
I have been having an issue on some websites where the enter key does not insert a visible line-break. They are there, but are not visible in the text field itself.
For example, I was recently writing on the Tomshardware forums and noticed that whenever I pressed enter more than once to create multiple consecutive line-breaks, only the first one was visible in the forum post editor. However, when using the forum post preview function, the line-breaks were actually there, even though I could not see them in the editor's text field. I attached a screenshot showing the problem.
I also noticed that this only happens on some websites. The text field I am writing in now works as expected - all line-breaks are visible. Chrome and Edge also work as expected on all websites, so this is only affecting Firefox.
Does anyone know how to fix this? :)
