Ad Killer for Quora™

Removes all ads, sponsored content, promoted content, and teasers for "premium" posts. Tries to leave all useful content in place. I wrote it because the other Quora™ ad blocker I found made the site unusable by also removing the upvote/downvote buttons and the sidebar. This tries to simply remove the ads and leave the site fully usable. Let me know if it misses any ads for you. Quora™ makes changes to their site from time to time that breaks something, all easily fixed. And note that if you make the extension's icon visible in the browser toolbar, it'll keep a running tally of how many ads it removes.
