A Firefox extension that makes webpages easy on the eyes. Similar to Chrome's “Dark Reader” extension. Owl can be activated by a hotkey combination (default: alt + shift + d) or thru a toolbar icon popup menu. The latter offers the following options: - Turn Owl ON/OFF - Use Classic Theme on this website - Disable Owl for this website - Always enable on this website _[Edited by nniicc, January 09]_
