Firefox 110 is out: here is what is new

Firefox 110.0 new features and improvements

Firefox 110 is a big update that introduces several changes and improvements.

Windows security improvements

Firefox for Windows supports GPU sandboxing now in the latest version of the browser. GPU sandboxing isolates the process of the graphics processor to neutralize malware attacks or reduce the impact that they can have on the system.

Firefox users may load about:support and check the GPU Process Sandbox Level value there to find out if it is enabled. Any value above 0 means that the sandbox is active.

The second Windows-specific feature enables users of the browser to block third-party modules that inject themselves into Firefox. The main idea behind the feature is to block third-party modules that cause issues, such as browser crashes.

To use the feature, load about:third-party in the Firefox address bar. Firefox lists all third-party modules on the page. A click on the “block this module” button prevents the module from being loaded in Firefox in the future. A restart is required to block the module. Modules may be unblocked at a later point by repeating the process.

Mozilla Firefox highlights modules that caused Firefox or some of its components to crash on the page. The following help page walks you through the process in detail.

Other changes and fixes

Firefox users may import data, bookmarks, history and passwords, from Opera, Opera GX and Vivaldi next to Edge, Chrome and Safari starting with this release.
Firefox users on macOS and Linux have Canvas2D GPU acceleration enabled now.
WebGL performance improvements on all desktop operating systems that are supported.
On Windows 10 and 11, overlay of hardware-decoded video with non-Intel GPUs us now supported, which improves video playback performance and video scaling quality.
The keyboard shortcuts Ctrl-Backspace and Ctrl-Delete may be used to clear date, time and datetime, local input fields. (Mac users need to replace Ctrl with Cmd).

Developer changes

Container queries and container query length units are now supported by default.
The color-gamut media query is now supported.
The list attribute is supported in <input> elements with type=”color” on Windows and Linux.
Serialization of native Error types now includes the stack property in workers when using Worker.postMessage() and structuredClone().
The midi permission of the Permission API is now supported.
ReadableStream now supports asynchronous iteration over the chunks in a stream using the for await…of syntax.
Various WebDriver BiDi improvements.

Enterprise changes

Mozilla supports downloading language packs now using the same syntax as downloading Firefox. This bug report has details on the feature. Basically, what it means is that it is now easier for Enterprises to install language packs via a policy.

Firefox supports the DisableThirdPartyModuleBlocking policy now, which prevents users from disabling injected modules on the about:third-party page of the browser. This does not apply to ESR.

Security updates / fixes

Firefox 110 addresses 19 different security issues in the web browser. The maximum severity of a vulnerability is high, which is second to the highest severity rating of critical.

Outlook

Firefox 111 Stable and Firefox 102.9 ESR will be released on March 14, 2023.
