Firefox 107 arrives with some changes and fixing 21 vulnerabilities

The new version of the popular web browser has already been released Firefox 107 along with which a long-term branch update, Firefox 102.5.0, has also been released. In addition to innovations and bug fixes, fixes 21 vulnerabilities. Ten vulnerabilities are marked as dangerous.

Seven vulnerabilities (collected under CVE-2022-45421, CVE-2022-45409, CVE-2022-45407, CVE-2022-45406, CVE-2022-45405) are caused by memory issues, such as buffer overflows and file rollbacks already released into memory areas.

These problems can potentially lead to the execution of malicious code when specially crafted pages are opened. Two vulnerabilities (CVE-2022-45408, CVE-2022-45404) allow bypassing the full screen mode notification, for example, to simulate a browser interface and trick the user with phishing.

Main new features of Firefox 107

In the new version of Firefox 107 we can find that the ability to analyze power consumption on Linux and macOS systems with Intel processors to the profiling interface (Performance tab in Developer Tools) (previously, power profiling was only available on Windows 11 systems and Apple computers with an M1 chip).

Another change that stands out from the new version of Firefox 107 is that added Cookie Full Protection mode, which previously applied only when opening sites in private browsing mode and choosing strict mode to block unwanted content (strict).

In Total Cookie Protection mode, se uses separate isolated storage for the Cookies of each site, which does not allow the use of Cookies to track movement between sites, since all Cookies set from third-party blocks loaded on the site (iframe, js, etc.) are linked to the site from which these blocks were downloaded and are not transmitted when accessing these blocks from other sites.

In addition to this, it is also noted that added support for image selection panels introduced since Android 7.1 (Image keyboard, a mechanism for sending images and other multimedia content directly to text-editing forms in applications.)

Improved performance of Windows builds on Windows 11 22H2 when handling link navigation in the IME (Input Method Editor) and Microsoft Defender subsystems.

Regarding the improvements for developers, it should be noted that CSS properties contain-intrinsic-size, contain-intrinsic-width, contain-intrinsic-height, contain-intrinsic-block-size, and contain-intrinsic-inline-size have been implemented to allow specifying the size of the element which will be used regardless of the effect on the size of child elements (for example, increasing the size of a child element may stretch the parent element).

The proposed properties allow the browser to immediately determine the size without waiting for the child elements to be drawn. If set to "auto", the last rendered size of the element will be used to set the size.

Of the other changes that stand out in this new version:

• Debugging plugins based on WebExtension technology has been simplified in web developer tools.
• Added option “–devtools” (webext run –devtools) to the webext utility, which allows you to automatically open a browser window with web developer tools, for example, to identify the cause of an error. Simplified inspection of popups.
• A Reload button has been added to the panel to reload the WebExtension after making code changes.
• Provided proactive loading of intermediate certificates to reduce the number of errors when opening sites over HTTPS.
• The texts in the included sites increase in content when the text is selected.
