Simple script to force the story text containing element on fanfiction.net & fictionpress.com to be left-aligned and the content wrapper element to use 99% width, massively improving readability if you use halfpage width on a widescreen display. Requires Scriptish.
Need updating for https protocol
The script is good, but when I first used it (on Tampermonkey), for some reason it didn't work. I had a hunch, and I looked at the script's... script. And as I thought, the script is set to work only with the http protocol site, it didn't account for the https protocol which is the default protocol for ffn now. It works after I turn it into http* though, which is small but without it would have made the entire script not work. I think you should update the script to account for it.
