Hide the Reddit sidebar until you actually need it.
Posts with lots of text in reddit can become extremely crowded by the sidebar, especially if you frequently have two windows open side by side. This extension fixes that by adding a widget to the top of the sidebar to collapse and expand it as needed. If you'd rather have the sidebar still there, but have the option to collapse it, you can change the default behavior in the options page.
