If using the share sheet slows you down, add this bookmarklet to Firefox. The bookmarklet will save the title as the action name and the url as a note. Omnifocus sets a due date of tomorrow to remind you to take it out of your inbox and process it and it autosaves to eliminate any need to interact with Omnifocus. Hit it and keep on going. The bookmark can be edited to share to specific projects and change the due date.

javascript:window.location='omnifocus:///add?project=&due=tomorrow&note='+encodeURIComponent(window.location)+'&name='+encodeURIComponent(document.title)+'&autosave=true'
