How to Auto-Clear Cookies for Specific Sites (and Auto-Reject Consent Banners)

Clearing cookies through your browser’s own settings is usually all-or-nothing: wipe everything, and you’re logged out of every site you actually wanted to stay signed into. Because of that, most people just… don’t clear cookies, ever, which means tracking cookies from sites they visited once months ago are still sitting there quietly. Meanwhile, nearly every site now shows a cookie consent banner on first visit, and the honest habit most people have developed is clicking “Accept” reflexively just to make the popup disappear — which defeats the entire point of the prompt.

These are two different annoyances, but they share the same root cause: cookies are handled at the browser level with no per-site nuance, so the only options are “keep everything” or “manually manage it constantly.”

Why blanket clearing doesn’t work

The reason people don’t just clear all cookies regularly isn’t laziness — it’s that a handful of sites genuinely benefit from persistent cookies (staying logged into email, a project tool you use daily, a shopping cart you don’t want to lose), while most other sites don’t need to remember you at all. A single global “clear everything” switch can’t distinguish between the two, so using it means re-logging into your daily tools constantly, and most people abandon it after a week.

What a per-site approach actually needs

• Whitelist or blacklist rules per site — some sites should be exempt from clearing entirely; others should never be allowed to accumulate cookies in the first place.
• A trigger tied to actually being done with a site, not a fixed timer — clearing the moment a site’s last open tab closes matches how people actually use the web far better than clearing on a schedule that might fire mid-session.
• A manual override for the odd one-off case where you want to clear something right now without waiting for the automatic rule.
• Separate handling for consent banners — auto-clicking “reject” (not “accept”) across as many sites and languages as possible, so the default outcome matches what most people actually want when they see the prompt, instead of the path of least resistance winning by default.

Two tools, one extension

Cookie Combo combines both halves of this: it auto-clears cookies for whichever sites you choose the moment their last tab closes, and — on the Pro tier — auto-rejects cookie consent banners as you browse, with coverage across 1,000+ sites and 40+ languages, so you stop seeing (and reflexively clicking through) the prompt at all on supported sites.

The free tier covers up to 5 site rules (whitelist or blacklist), clearing on tab close and full browser close, a manual “clear cookies now” button for whatever site you’re currently on, and a simple status view showing which rule applies to the current tab.

Pro removes the 5-site cap entirely and adds finer control for people who want to go further: per-cookie-type clearing (so you can drop tracking cookies while keeping login sessions intact on sites you didn’t explicitly whitelist), idle-based clearing for tabs left open for days at a time, a “clear all except whitelist” mode that flips the default to clearing everything except the sites you name, a deeper clean that also wipes localStorage, IndexedDB, and cache (not just cookies), settings synced across your devices, and a clearing log so you can see exactly what was cleared and when.

A reasonable starting setup

Start by blacklisting the handful of sites you know track you and don’t need you logged in — shopping sites you browse but rarely buy from, news sites, anything with heavy ad tracking. Leave the tools you use daily off the list entirely. If consent-banner fatigue is your bigger pain point day to day, that’s the strongest reason to go Pro — auto-reject alone removes a click you’re currently making dozens of times a week.
