Cliqz is based on the Firefox browser. Firefox stopped their support for Windows XP/Vista in April 2017 ( and we had to follow suit. For security reasons, we cannot provide older versions of Cliqz that are compatible with Windows XP/Vista.

We advise to update to a newer operating system. That said, there is a potential alternate: Firefox offers an Extended Support Release (ESR). While this browser version does not get any new features via updates, it receives the most important security updates (

You can install the Cliqz extension for Firefox on ESR ( Add an ad-blocker and HTTPS Everywhere, and you’ll end up with a similar package as the Cliqz browser.

  • Go to the Cliqz for Desktop download page with any browser (e.g. Apples Safari).
  • Click “Download” for Cliqz for Mac. A little window to open the file will pop-up. Choose “Open with Disk Image Mounter” and click ‘ok’. That’s how you download the installation file for Cliqz.
  • As soon as the download is finished, the so called disc-image (Cliqz.dmg) opens in a separate window. Drag the Cliqz logo into the program folder with your cursor. Note: If you don’t see that window, click on the file you just downloaded (Cliqz.dmg) to open it.

  • Make Cliqz your standard browser, by confirming the option in the pop-up-notification. This means, that hyperlinks will now be opened with Cliqz by default.

Add-ons are immensely useful – but they have a downside as well. A number of them send large amounts of usage data, including personal information, to their respective companies. Several of them even go on to sell this data. In addition, our research shows that many users aren’t fully aware which add-ons are installed or activated in their browser. This happens through no fault of their own – many add-ons are automatically installed along with other programs without the user’s knowledge.

The potential dangers associated with add-ons has actually been a topic of some interest lately – the German press recently unveiled a massive breach of privacy for a certain add-on, with some help from a study conducted by Cliqz ( If you’re interested, you can read up on the issue here:

We want to create an easily controllable environment in our browser that allows us to do our utmost to ensure the privacy and protection of our users. Since we don’t have a way to ensure the safety of add-ons across the board at this time, we unfortunately do not allow their installation in Cliqz.

However, we have included several individual add-ons that have undergone a strict safety evaluation into our browser. At the time of our most recent release, we have included Ghostery, HTTPS Everywhere, LastPass and the beta version of our own ad blocker.

We decided to integrate LastPass because many users requested it and LastPass gave us the option of checking their code in order to understand how they handle user data. This also applies to the open source password manager Bitwarden.

In the future we might check other password managers, like 1Password or Dashlane, but only if we have access to the code and a stable contact with the respective company.

Did you know that you can use a master password in Cliqz for Mac / Windows? Its advantage is that the data will never leave your machine and your passwords are not stored on a server. That’s safe and easy to use.

To set a master password, go to the Menu > Options > Privacy & Security > History and activate option ‘Remember history’.
Then Go to Menu > Options > Privacy & Security > Forms & Passwords and activate the option ‘Use a master password’.

“Top News” informs Cliqz users about the most important events of the day. All linked articles originate from respected and trustworthy news domains within the respective countries.

In order to determine the most relevant news for our users, we first collect and process all articles that were published by these sources, which we then compare among each other and form clusters around current events. The magnitude of these events, their presence on homepages of different news outlets and their time of publication results into a list of Top News, updated hourly to let you be on top of the news.

If you do not want to see news on the Cliqz Tab, you can deactivate them. To do so, click the gear-wheel symbol in the top right corner of the Cliqz Tab. This menu allows you to customize your Cliqz Tab according to your personal taste. You can deactivate the respective options (Most visited sites, Favorites, Search bar, News) by simply flipping the switch. The remaining elements will collapse to the center automatically.

Learn more about Top News on Cliqz Tab.

We are currently not officially supporting Linux, but if you are adventurous, please feel free to try our internal build or build it yourself, the steps can be found here.

  • Cliqz automatically updates by default. However, you can also start an update manually any time you like.
  • Windows: Click on the browser menu icon in the top right corner of the browser and click ‘help’. Then, click ‘about Cliqz’
  • Mac: Click Cliqz up in the window and then click ‘about Cliqz’
  • The window ‘about Cliqz’ opens and automatically starts looking for updates. If there are updates available, they will be downloaded automatically.
  • If the updates are ready to be installed, click the button ‘to finish the update, restart Cliqz’

Follow these five steps to set Cliqz as your default browser in Windows 10:

  1. Click the menu button in the top right corner of the browser window and select “Options”.
  2. In the “General” panel, click on “Make Default”. This will open the “Choose default apps screen” in the Windows settings app.
  3. Scroll down and click the entry under “Web browser”. It will say either “Choose your default browser” or the name of the current browser that is set as default.
  4. In the “Choose an app screen”, click Cliqz to set it as the default browser.
  5. Cliqz is now your default browser. Close the Settings window to save this change.

Tracking is very common online: trackers collect insecure data on three quarters of all web pages, data which enables the identification of the user and allows to track him through the web. Cliqz puts a halt to those practices. It overwrites your information, so that trackers cannot identify you. In the top right corner of the browser you can always see how many trackers are currently being blocked and learn more about those specific trackers.

In addition to that, Cliqz gives you full control over your data. Cliqz does not store personal data, everything stays on your device and under your control. In the transparency-dashboard you can see which data your browser works with and what happens to it. You can always have a look at the transparency dashboard by yourself. Just click the Cliqz-Symbol in the top of your browser (blue circle with black arrow) and choose ‘transparency-dashboard’. Alternatively, type about:transparency in your browser bar and hit enter.

Read more about our Anti-Tracking here.

Disclaimer: Currently the transparency dashboard only works in German. We’re working on an adequate translation.

Cliqz offers the Ghostery anti-tracking tool as a free add-on for the Cliqz desktop browser for Windows, macOS and Linux. You can install Ghostery via the “Security” menu (“Extended Privacy Control”) in the browser settings. Then you will find a small ghost (“Ghosty”) next to the URL bar. A click on it shows you an overview of the trackers found on the opened web page, which can then be blocked individually or all together.

Unlike Cliqz’s anti-tracking, in Ghostery all scripts and elements are permitted by default. You must take action and manually determine which of the hidden services on the visited Website you want to block. To make the decision easier, Ghostery provides some background information about the tracking elements found.

A count badge on the Ghostery icon indicates how many tracking services are active on the current page. The value is usually different from the number displayed in the Control Center (Q-Menu) of Cliqz because Ghostery indicates the number of tracking scripts found, while Cliqz shows the number of tracking requests. After clicking on the Ghostery icon, you will see a list of the trackers found, sorted by categories such as advertising, website analytics, social media, audio/video player, comments or customer interactions. There you can customize the settings for the respective page. Only you have full control over your data. Here you can find more information about the Ghostery integration.

Cliqz is the world’s first browser with an integrated fast-search-engine. When you enter queries, you will see suggestions for websites, which suit your input and ideally give you the required information.

Our independent index suggests up to three websites in real-time, which are chosen because of their relevance. That way, Cliqz makes it completely unnecessary to visit search engine’s result pages when you’re merely doing a navigational search.

It is of course possible that your query does not match any relevant results in our quick-search-window. That’s no problem, though, because you can always us a conventional search engine as a supplement for deeper research. To do that, there’s nothing to do but to hit Enter after you typed your query into the browser bar – you’re probably used to that by other browsers you used.

We have received reports from users who had issues playing videos on the Cliqz desktop browser.

Please try the following trouble-shooting:
Is your Flash Player up to date? (a program for streaming / playing multimedia content including videos, among others)
To download the latest version of Adobe Flash Player, visit

– Is your Cliqz browser up to date?
To see what version of Cliqz you have on Windows, click on the menu icon in the top right corner of the browser window.

In the little window that opens, click on the questionmark icon “?” at the bottom (next to “Customize”). This will open a little menu that includes an item called “About Cliqz”. Click on it to see the current version of the browser, as well as further information.

On Mac, you can find the current version of Cliqz by clicking on the navigation item “Cliqz” in the top left corner of your screen. (Note: this is only visible, if Cliqz is open and the active program.) Next, select “About Cliqz”. This will open a little window with information including the current version number.

You can download the latest released version of Cliqz here.

– Is the website not allowing you to watch videos with enabled Anti-Tracking?

Please try the following:

  • Open the Control Center over the upper-right corner next to the address bar (the blue circle with the black arrow)
  • Switch off the Anti-Tracking.

Warning: With this settings you are not protected against trackers anymore. Do not forget to switch the Anti-Tracking on again after watching the video.

– Is the website loading the videos through not secure connections?

HTTPS Everywhere is an extension that aims to make connections to websites secure automatically (when possible). Normally, connections to websites would be made with the unencrypted HTTP protocol. This makes it possible for attackers to listening on, or even manipulate, the connection. To prevent this, many website operators also offer an encrypted connection over HTTPS.

You can temporarily disable HTTPS Everywhere. Click on the Q-Menu (the blue circle with a black mouse pointer), and where it says ‘Prefer HTTPS’, toggle the button to ‘OFF’.

If the video is still not playing after all – please send us the URL to the video through the Support form.

While browsing in a Forget Tab or Forget Window, Cliqz does not store the following data on the computer:

  • History: Visited pages will not be saved to the computer’s history and thus cannot be found via the library or the history results in the search.
  • Cookies: Cookies store information about, for example, page settings, logins and data that is used for plugins like Adobe Flash Player. In Forget Mode this information is not saved.
  • Form fields and search box entries: Text entered into text boxes or search functions on websites is forgotten instantly.
  • Passwords: Newly entered passwords will not be remembered either.
  • Download list: You can download and save files just like in Normal Mode. However, files downloaded in Forget Mode will not show in the downloads menu.
  • Temporary data: Temporary data and data required for offline usage cannot be saved in Forget Mode.

By the way, the data listed can also be removed from the computer after visiting a specific website in Normal Mode via the functions “Reload in Forget Mode” or “Always load in Forget Mode”. If you have opened the respective website in a normal tab or window, you can right-click on its tab to open the tab-menu and select one of the options.

  • “Always load in Forget Mode” automatically deletes the data listed above for this domain from the computer. The next time you visit the website, Cliqz will automatically open it in Forget Mode.
  • “Reload in Forget Mode” will ask for a confirmation to remove the data belonging to this domain from the computer. If you choose “yes” the data will be permanently removed. “No, keep data” will not delete them. If you visit the page again, it will open in Normal Mode.

We are happy to provide a checksum for the current browser version upon request. Please add the following information to your message:

  • Operating system (Windows, Mac or Linux)
  • Language (English or German)
  • Where would you like to download Cliqz from? (for example or website, another website, etc….)

By the way, if you are interested to learn what a checksum is, Wikipedia offers a general description, among others.

In Firefox you can surf in private mode; this means, for example, websites you visit in private mode are not added to your history. Cliqz changes nothing about this.

In private mode, Cliqz only shows you results from the already existing history. To use Cliqz in the private mode, simply open a new private window in Firefox.

Cliqz for Firefox is optimized for usage in Germany and German language. You can try the extension in other languages and countries, but the quality of the website suggestions doesn’t reach the same level. Furthermore, some features such as smart Cliqz are missing.

We are working hard to support more countries and languages. Check back soon for updates.

A fully funded start-up, Cliqz was able to focus on the development of our technologies and on increasing user satisfaction when starting out. Only recently we began building our business model “Cliqz Offers”.

“Cliqz Offers” is a new service aiming to provide users with selected offers that match specific current interests. The function is part of the browser and gets triggered by pre-defined conditions only. Certain search queries or website visits, for example, could prompt the function.

Unlike other similar services, the detection of user intents does not happen on external servers, but solely inside your browser. As a result, your data do not leave your computer and remain under your control.

Cliqz GmbH is a start-up based in Munich with 118 creative professionals from 33 countries. Our goal is to make navigating the net fast, simple and clearly structured.

The company is owned by Burda and Mozilla. Cliqz operates independently from other Burda units and does not exchange any data with them. Websites owned by Burda are not treated any differently from other websites (e.g. with respect to search ranking or anti-tracking). In February 2017 the Cliqz GmbH has acquired the Ghostery brand and Ghostery’s consumer operations.
