Cliqz for Windows is automatically switched to 64-bit version

As announced in mid-February, all users of the 32-bit version will now receive an upgrade to the 64-bit version. This makes the Cliqz Browser even more stable, secure and faster.

The 64-bit version of Cliqz has more security and fewer crashes

If you used the 32-bit version of Cliqz for Windows so far, we will automatically migrate your browser to the 64-bit version with the latest update. The only prerequisite is that your computer meets the minimum system requirements: a 64-bit operating system (Windows 7 or higher) and >2 GB RAM. You can continue to use your user profile with all your bookmarks and settings.

What’s the difference between 32-bit and 64-bit?

64-bit applications can access more memory and are less likely to crash than 32-bit applications. The 64-bit architecture also provides better support for a security feature called Address Space Layout Randomization (ASLR).

This security mechanism, which is an integral part of any modern operating system, is involved in preventing exploitation of memory corruption vulnerabilities. It guards against buffer-overflow attacks by randomizing the location where system executables are loaded into memory. This makes it far more difficult for attackers to guess the position of processes and functions in memory. If an attacker tries to exploit an incorrect address space location, the target application will crash, stop the attack and alert the system. In this way, ASLR contributes to general system security.

How to reverse the 64-bit update

If for some reason you don’t want to use the 64-bit version of Cliqz for Windows, you can revert to the 32-bit version. Simply download the latest 32-bit version from the Cliqz website and reinstall it. After that, the 32-bit version will no longer automatically be migrated to the 64-bit version.

When downloading from our website, new users will automatically receive the recommended browser version for their system (based on OS and RAM). The same applies to the Cliqz Browser for Mac, which has also been optimized for 64-bit. Windows users have the additional option to manually select the version they wish to install.

Try the 64-bit version of the Cliqz Browser right now. We look forward to your feedback.
