Set your privacy preferences once.
BrowserConsent is a free, open source extension for Chrome and Firefox. Tell it once how you want cookie banners answered, Reject all or Accept all, and it gives every website that answer for you. It also shows you which sites track you anyway.
Needs Chrome 111 or Firefox 140, or newer.
From the store for Chrome, by hand for Firefox.
BrowserConsent is in the Chrome Web Store, which also keeps it up to date. For Firefox you load it yourself from the latest release on GitHub.
Chrome, Edge, Brave and other Chromium browsers
- 01Open BrowserConsent in the Chrome Web Store.
- 02Click Add to Chrome and confirm.
Installed an earlier copy by hand? Remove it and install from the store. Chrome treats the two as different extensions, so your settings and receipt do not carry over.
Firefox
- 01Download katla-browserconsent-firefox-1.1.1.zip.
- 02Open
about:debugging#/runtime/this-firefox. - 03Click Load Temporary Add-on and pick the zip.
Firefox only keeps an unsigned add-on until it restarts, so you will need to load it again next time.
A welcome page opens once it is installed. BrowserConsent does not run on any website until you have chosen Reject all or Accept all there and ticked each statement.
One answer, given to every site.
Most websites ask for your cookie consent on your first visit. BrowserConsent gives them the same answer every time, so you do not have to.
Answers cookie banners for you
Pick Reject all or Accept all once. Where a consent platform has its own JavaScript API, BrowserConsent records your choice through it, so the site’s consent record is updated the way the platform intends. Otherwise it presses the banner’s matching button.
Knows the banners you actually meet
It recognises 39 consent platforms, among them OneTrust, Cookiebot, Usercentrics, Didomi, Sourcepoint and TrustArc. A banner it does not recognise is left alone.
Warns you about trackers
The toolbar badge turns red when a site sets a tracking cookie or sends a pixel before you have answered its banner, or after you said no. It knows 34 common trackers, such as Google Analytics, Meta Pixel and TikTok.
Blocks them, if you want
Switch on blocking and those trackers are stopped on every site that does not have your consent. It is off until you turn it on, because some sites may not work fully with it.
Keeps a record
You get a receipt of exactly what you agreed to and a log of every banner answered for you. Export them or withdraw at any time.
Your own click always wins
Banners you have already answered are left alone, and BrowserConsent steps aside as soon as you click or type on a page. If a banner has no way to reject on its first screen, it is left for you.
Accept all is a real consent
Websites and their partners may then use cookies for analytics, personalisation and advertising under their own privacy policies, so BrowserConsent asks you to agree to that separately.
39 consent platforms, recognised by name.

Katla collects nothing.
BrowserConsent has no servers, no analytics and no remote code. Your settings, receipt and activity log stay in your browser, and uninstalling removes them.
- RUNS ON
- Chrome, Edge, Brave and other Chromium browsers, and Firefox
- STARTS
- Only after you have read what it does and agreed to it
- DATA
- Everything stays in your browser. Nothing is sent to Katla.
Run a website? This is the other side of the banner.
Katla is a cookie consent platform for websites. It scans your site, classifies the cookies it finds and gives you a banner that stays up to date with them. BrowserConsent is the visitor’s side of that. Want to see what your own site sets? Run the cookie checker.
