No. ElementHider is a lightweight content script that watches for page changes locally — it makes no network requests while you browse, so your pages load at full speed. Most users report zero noticeable impact on performance.

Yes. ElementHider handles dynamic content correctly on all three. On YouTube it hides matching video titles and descriptions as they load; on Reddit it filters post titles and comments; on X / Twitter it catches new tweets in your feed in real-time — no page refresh needed.

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.

The free version includes keyword hiding, point-and-click hiding, blur mode, site-specific rules, test mode, and smart suggestions. The Supporter Pack (€9.99, one-time) adds Groups (mute a whole topic in one click), Highlight and Replace display modes, Regexp matching, Dark mode, and Smart Learning with the Keyword Map.

Every rule is fully editable and deletable from the extension popup at any time. You can also use Test mode before committing — it outlines matched content in green, letting you preview the effect without actually removing anything from the page.

Yes. ElementHider is available on both the Chrome Web Store and the Firefox Add-ons store. Your Supporter Pack license works across both browsers — just verify with your Ko-fi email in the extension popup on any device you install it on.

Absolutely. ElementHider is a general-purpose content filter — people use it to reduce feed noise, remove distracting sidebars and recommendation panels, hide layoff headlines while job searching, clean up social media feeds, or simply focus on what they actually came to read. If the text or element appears on a webpage, you can hide it.

Yes. Keywords are stored in your browser's built-in sync storage, so they automatically appear on every device where you're signed in to the same browser profile — no account or extra steps needed.

Hide removes matching content completely — the text or element becomes invisible. Blur keeps the content in place but makes it unreadable by default; hover over it to reveal the text when you're ready. Use Blur when you want the option to check whether something is worth reading, and Hide when you simply don't want to see it at all.

Keyword hiding already hides the whole block that contains a match — not just the word itself. You can control how far up the page the hiding reaches by adjusting the keyword's hiding reach: a higher value hides larger parent elements, so a single keyword can take out an entire card, post, or section. For cases where you want to hide something with no recognisable text — a sidebar widget, an ad unit — the point-and-click picker lets you click any element on the page and ElementHider generates a CSS selector rule that hides it permanently on that site.

Yes — it shipped in v1.1.1, live now on both the Chrome Web Store and Firefox Add-ons. It watches which words tend to appear alongside content your own keywords already hide — e.g. "leaked" or "ending revealed" showing up near a "spoiler" match — and suggests them as one-click additions, entirely on-device with nothing ever sent anywhere. Your original keyword's own matches always hide on their own; you can opt individual keywords or groups in, combine a suggestion with your keyword so it also catches cases where the keyword alone wouldn't have (broadening what gets caught, never restricting it), and adjust the Smartness threshold per keyword or group to trade off more suggestions vs. higher confidence.
