Element Rules 作成者: Max

Point at anything on a page and turn it into a rule: hide it, blur it, remove it, click it, or change
it — immediately, after a delay, when it scrolls into view, or on the next in-page navigation.

Pick, don't write CSS. Hover to highlight, use ↑/↓ to walk up and down the DOM, and click once to
act. Prefer more control? Edit the generated selector before saving, or switch the rule to "all similar
elements" so everything that matches gets the same treatment.

Rules survive reloads. Every rule is saved and re-applied automatically on the pages it belongs
to — per-site by default, with optional URL filters, exclusions, path prefixes, or all sites at once.

• Hide or blur — compiled into one stylesheet applied before the first paint, so the element never
  flashes on screen.
• Remove, click, plus style, class, attribute and text edits.
• Media controls: play, pause, mute, volume, playback speed, seek, fullscreen.
• Scroll into view, focus, and dispatch custom events.
• Destructive actions offer an Undo for a few seconds.

• As soon as the element appears — works with infinite scroll and late-loaded content.
• After a delay, counted either from when the element appears or from page load.
• When the page finishes loading.
• When the element scrolls into view.
• After navigating within the page, for single-page apps.
• Keep retrying until something matches.
• Only when you run it — from the popup, the right-click menu, or a keyboard shortcut.

The rule editor and the popup's quick edit can apply an unsaved draft to the live page, report how many
elements matched, and undo the test. A preview never touches your saved rules.


A preset library covers generic patterns only: consent banners, privacy dialogs, age gates, newsletter
popups, registration walls, sticky headers, floating video players, chat widgets, share rails, and
autoplaying or loud media. Presets stay off until you install them.


Import a JSON array of { label, selector, action, site, enabled } objects and they are mapped onto the
rule model. Unsupported fields are dropped with a note in the import result.

• No network access of any kind — no analytics, no telemetry, no remote configuration, no remote
  code. Everything ships inside the add-on.
• Rules and settings live in your browser's local extension storage and never leave your machine unless
  you export them yourself.
• No accounts, no sign-in, no tracking.
• The add-on's own interface lives in a shadow root and never touches the page's globals.

• Access your data for all websites — a general element blocker has to look at the page you point
  it at; that is the entire feature. Pages are processed locally and nothing is sent anywhere.
• Storage — to keep your rules and settings.
• Context menus — for the right-click entry that starts the picker.

• Alt+Shift+E — start the picker
• Alt+Shift+R — turn rules on or off for the current site

Both can be rebound in the add-on manager.

Open source and MIT licensed. The add-on ships no site-specific rules: if a page needs a selector of its
own, you create it at runtime with the picker.
