Is it possible to scroll exactly one line with firefox?

more options

If you read long texts with a web browser, it is easier for the eye to have something that guides them.

One simple solution is to read at the bottom of the screen and scroll down one line after the other.

Up to now I could not find a way to scroll exactly one line with firefox. Cursor-Down moves more than one line in my setup.

A plugin which provides a ruler or something like this would work, too.

In about:config, setting toolkit.scrollbox.verticalScrollDistance to 1 gives you a result close to 1 line, but because text sizes and line heights may vary, I'm sure it's not going to give you perfect results.
