Greetings all, Is there a way to change the margins of viewed markdown files by going into, ''for example, about:config'' or another way? Would this or some other commands allow me to change the left and right margins? I would like to change (widen primarily) the margins of markdown files when I view them on my Firefox browser. I use a lot of Markdown, for writing, scientific work (RMarkdown), and note-taking. I am currently using a Markdown text editor (Abricotine, not that this should matter) that simply calls up Firefox and sends the text/markdown to the screen. However, when I view the .md files the margins seem very small to me. Cheers,
