Pocket is great for this. Just hit that pocket icon and close the tab. Now it's gone from your life forever. I just hope that the browser extension will keep working even if the service closes down, so I can keep putting things into Pocket and never ever read them.
That is, until you collect a few dozen thousand pocket bookmarks at which point you are at "there was this thing... how was it called?... have I saved it to pocket? Maybe I did... or not?"
