Following closely, a patch release for Firefox 96.0.1 has been issued that resolves a bug in Firefox 96 related to parsing the 'Content-Length' header, which manifested during the use of HTTP/3. The issue stemmed from the case-sensitive search for the string 'Content-Length:', causing it to miss lowercase variants like 'content-length:'. Additionally, this version fixes a Windows-specific problem that disrupted the proper functioning of bypass rules for proxy settings.
Moreover, an issue in the HTTP/3 code that caused infinite looping when trying to access websites via the HTTP/3 protocol with DoH (DNS over HTTPS) has been addressed, though it was not mentioned in the release notes.
Additionally, the new version of the mobile browser Firefox Focus for Android includes a Total Cookie Protection mode, which means that each site has a separate isolated storage for cookies, preventing cookies from tracking movement across sites. All cookies set by third-party blocks (iframes, js, etc.) loaded on the site are tied to the main site and are not passed when accessing these blocks from other sites.
To address issues on websites caused by the blocking of external scripts, Firefox Focus has also added support for the SmartBlock mechanism, which automatically replaces tracking scripts with placeholders that ensure the website loads correctly. Placeholders have been prepared for some popular user tracking scripts listed by Disconnect, including scripts for Facebook, Twitter, Yandex, VKontakte, and Google widgets.
Let’s recall that the Firefox Focus browser is focused on ensuring privacy and giving users complete control over their data. Firefox Focus includes tools for blocking unwanted content, such as ads, social media widgets, and external JavaScript code for tracking movements. Blocking third-party code significantly reduces the volume of downloaded materials and positively affects page load speed. For example, compared to the mobile version of Firefox for Android, pages load on average 20% faster in Focus. The browser also features a button for quickly closing the tab while clearing all associated logs, cache entries, and cookies. A downside is the lack of support for extensions, tabs, and bookmarks.
In Firefox Focus, the sending of telemetry data with anonymized statistics on user behavior is enabled by default. Information about the data collection is clearly indicated in the settings and can be disabled by the user. Besides telemetry, upon installation of the browser, information about the source of the application (campaign identifier, IP address, country, locale, OS) is sent. If the data sending mode is not disabled, information about the frequency of application usage is periodically sent afterward. The data includes details about application launch activity, used settings, frequency of opening pages from the address bar, and the frequency of search queries (information about which specific sites are opened is not transmitted). The statistics are sent to servers the third-party company Adjust GmbH, which also possesses data about the device's IP address.
