LibreWolf is a web browser that is primarily aimed at users who attach particular importance to data protection and security. The software is based on Mozilla Firefox, but it removes all elements that could potentially collect user data. LibreWolf puts data protection above all other aspects and accepts some restrictions in return. But how does the browser perform in everyday use? Is it a real alternative to Firefox or only of interest to a small target group?
Data protection is becoming increasingly important on the internet. While large browser providers such as Google and Microsoft collect data about their users’ surfing behavior and evaluate it for advertising purposes, alternatives such as Firefox are trying to better protect privacy. But even Mozilla relies on Google as its search engine by default and collects telemetry data in order to further develop its software. LibreWolf goes one step further and removes all data transfer to third-party providers. The browser blocks tracking, prevents fingerprinting, and ensures that as few traces as possible are left behind when surfing. This has advantages for users who want to remain anonymous, but it can also lead to restrictions when using certain websites. In this article, we take a detailed look at LibreWolf, its strengths, and its weaknesses.
Overview
LibreWolf Without Advertising and Tracking
A key feature of LibreWolf is the consistent implementation of data protection measures. While other browsers offer different levels of protection, LibreWolf is set to completely block tracking and advertising from the outset. Users do not need to install any additional add-ons or manually adjust settings—all privacy-friendly features are already activated. This means that websites cannot set any analysis or advertising cookies, which makes it much more difficult to track surfing behavior.
The integrated protection against fingerprinting is particularly noteworthy. Many websites use technical features of the browser to identify users even without cookies. These include the screen resolution, installed fonts, and the hardware configuration of the device. LibreWolf ensures that this information is obscured so that websites cannot create unique profiles. This protection is particularly important for users who want to be anonymous online, but it can also mean that certain pages are not displayed correctly.
Another advantage is that LibreWolf does not display any advertising content by default. The browser includes the “uBlock Origin” add-on by default, which not only blocks advertising but also filters known tracking scripts and potentially harmful websites. As a result, websites load faster, and the risk of being directed to fraudulent or infected sites is reduced.
Firefox Alternative with Limitations
However, the advantages mentioned also come with some limitations. Although LibreWolf is based on Firefox, there are some significant differences that affect everyday use. One of the biggest differences is the lack of automatic updates. While Firefox regularly installs new versions on its own, LibreWolf users have to manually check for updates and install them. This should also be done before use to ensure the necessary security.
If you always want to use the latest version, you can install the “LibreWolf Updater” add-on, which informs you of new updates. Without this additional add-on, however, there is a risk that users will use outdated software, which can pose security risks.
The default language of LibreWolf also differs from Firefox. After installation, the browser is set to English by default. If you want to change the user interface to German, you have to adjust this yourself in the settings under General > Language. Although this is not a major obstacle, it could put off some users who expect to be able to use it immediately without any additional configuration steps.
Another detail is the choice of default search engine. While Firefox uses Google by default, LibreWolf relies on DuckDuckGo, a search engine known for its data protection approach. DuckDuckGo does not save any search histories and does not create any user profiles. However, if you are used to Google search, you have to set it as the default manually. This is possible, but requires a few additional steps in the settings.
Another feature of LibreWolf is that the browser automatically deletes all cookies, the cache, and the history after each session. While this provides more data protection, it can be problematic for users who want to log in to websites permanently. For example, anyone who accesses online services and does not want to re-enter their access data each time must define specific exceptions in the settings under Cookies and website data. Overall, LibreWolf therefore offers a high level of security, but requires a certain willingness to adapt on the part of users.

Protection Functions Can Sometimes Interfere With Websites
LibreWolf’s strict data protection measures not only have advantages, but can also mean that certain websites do not function properly. Some sites rely on fingerprinting methods to uniquely identify users and deny access if they do not receive sufficient information. This can be the case, for example, with online banking portals or streaming services that use certain security mechanisms to recognize devices.
In such cases, it is possible to deactivate the protective measures for individual pages. LibreWolf offers a shield icon in the address bar, which users can use to set an exception for certain websites. If the protection function is deactivated for a page, it can be loaded normally again. However, you should be careful and only exclude trustworthy sites from the data protection measures.
Another problem can occur if websites rely on cookies being stored over several sessions. As LibreWolf deletes all cookies by default when the browser is closed, it can happen that users have to log in again every time they visit or that certain page settings are lost. If you want to change this behavior, you have to define specific exceptions for individual websites.
These restrictions mean that LibreWolf is not suitable for every user. Those who regularly work with websites that have strict security requirements or offer many interactive functions may be better served by Firefox or other browsers.
Who Is LibreWolf Suitable for?
LibreWolf is a good choice for users who attach particular importance to data protection and are prepared to forego some comfort functions. The browser is one of the best options available, especially for people who want to surf anonymously. It is also suitable for users who like Firefox but do not want telemetry and tracking functions.
However, there are also user groups for whom LibreWolf is less suitable. People who prefer convenient use and automatic updates may have difficulties with the manual updates. Users who frequently use online services and rely on a permanent login also have to deal with the strict cookie deletion mechanisms.
Overall, LibreWolf offers one of the most consistent data protection solutions for everyday surfing. Anyone who wants maximum privacy and can come to terms with the restrictions will find LibreWolf a strong alternative to conventional browsers.
