How it works

Up and running in seconds.

Add your keywords

Type the words or phrases you want to block. Or just click any element on a page — ElementHider generates a rule for it instantly.

ElementHider scans every page

The extension watches every page you visit and catches new content as it loads — works on infinite feeds, SPAs, and dynamic sites.

Matching content disappears

Hidden, blurred, highlighted, or replaced — whichever way you choose. No refresh needed, no clutter, no spoilers.

Free features

Everything you need, nothing you don't.

No accounts, no trackers, no bloat. All your rules run entirely in your browser.

Hide by keyword

Type a word or phrase and every matching section of every page vanishes — spoilers, distractions, brands, anything you choose.

Annoying sidebar 👆

Point & click hiding

Click any element on a page — a banner, a feed, a sidebar — and ElementHider turns it into a permanent hiding rule.

The surprise twist left everyone speechless. (hover to reveal)

Blur mode

Soften content instead of removing it. Hover to reveal when you're ready — no accidental spoilers, total control.

Works as you scroll

Hides new content as it loads dynamically — handles infinite feeds, lazy-loaded posts, and single-page apps without a refresh.

Would hide "The ending of episode 8..."

Test mode

Preview what would be hidden before any content disappears — outlined in green. Safe to experiment without losing anything.

Only on reddit.com

Site-specific rules

Pin any keyword to a specific domain so it only fires on reddit.com or youtube.com — not on every site you visit.

Never. All your keywords and rules are stored locally in your browser's sync storage — nothing is ever transmitted to us or any third party. The sole exception is the optional Supporter Pack verification, which stores only your email address to confirm your purchase status.
