This version is quite outdated I am sure, but it works like a charm still for important functions!
A feature I would like to suggest is the ability to right click and copy the descriptions to the clipboard!

It's a really handy (and I think the only) addon for reading about about:config entries.
However the addon is outdated and needs entry updates!
