How to Block Reddit Ads in 2026

Reddit's ads are quieter than YouTube's or Twitch's, but they are also more numerous — and by design they blend into your feed. This guide covers the mechanics and the clean way to hide them in 2026.

For the underlying mechanism, see how ad blockers work. For the broader tracking picture on social platforms, see social media privacy.

What Reddit ads actually look like

Reddit has four ad formats worth knowing:

• Promoted posts in the feed, styled to look like normal posts with a small "promoted" badge.
• Sponsored comments in threads, usually near the top, again badged.
• Sidebar ads on old Reddit and community sidebars.
• App and premium interstitials: "Get the Reddit app", "Try Reddit Premium", "You've hit your read limit" prompts.

Only the sidebar ads look like traditional banner ads. The rest are rendered inline with normal content.

Why Reddit is trickier than banner-heavy sites

On a typical publisher site, ads come from a small number of third-party domains (Google Ad Manager, Amazon, a few SSPs). A network filter list blocks the domain, the ad never loads, done.

Reddit serves its ads from its own API, alongside real posts, from the same endpoint. From the network perspective, a promoted post request looks identical to a normal post request. The only reliable "this is an ad" signal is in the rendered HTML — a promoted flag, a specific badge, a specific CSS class.

Blocking Reddit ads therefore requires cosmetic filters (element hiding), not network filters. Any blocker without cosmetic filter support will miss the majority of Reddit ads.

The clean 2026 setup

1. Install NovaBlock from the Chrome Web Store or Firefox Add-ons.
2. Open reddit.com. Promoted posts, sponsored comments, and app interstitials disappear on new Reddit, old Reddit and sh.reddit.com.
3. If you use old.reddit.com, sidebar ads are already gone via network rules.

That is the whole setup. No custom filters, no per-subreddit configuration.

Comparison

Mobile

Options in order of quality:

• Firefox for Android + NovaBlock on old.reddit.com. The most reliable option. Old Reddit is denser, faster, and much easier to keep clean.
• DNS-based blocker (NextDNS, AdGuard DNS). Blocks tracking, does not hide promoted posts inside the app.
• Official Reddit app: no ad blocker will work here. Reddit Premium is the only clean option.

Old Reddit versus new Reddit

If you dislike ads on Reddit, the fastest quality-of-life change is to switch to old.reddit.com. It is denser, faster, has fewer ad slots by default, and is easier for any blocker to clean. You can force old Reddit for all reddit.com URLs in your preferences (Settings → Feed → "Opt out of the redesign").

New Reddit and sh.reddit.com are the current defaults and still block well with NovaBlock, but if you prefer a stripped-down experience, old Reddit is a no-cost improvement independent of ad blocking.

Pros and cons

Pros

• Cleaner feed, faster scrolling, less visual noise.
• Fewer prompts to install the Reddit app or upgrade to Premium.
• Trackers on Reddit get blocked as a side effect — Reddit ships Google Analytics, Meta Pixel and other third-party pixels by default.

Cons

• If a subreddit uses promoted-post-style CSS for a legitimate community post (rare, but happens), it can also get hidden. NovaBlock's element picker un-hides in one click.
• The Reddit mobile app is off-limits.

What about the mod-tool subreddits?

Nothing changes there. Cosmetic filters are scoped to the ad selectors, not to any subreddit-specific styling. Mod queues, mod mail and old.reddit.com's mod interfaces continue to work.

Conclusion

Reddit ads are subtle by design, which makes cosmetic-filter support the thing that separates a working Reddit blocker from a broken one. NovaBlock ships that support by default, and pairing it with old.reddit.com gives you the cleanest possible Reddit in 2026. See features for the full protection list.
