Firefox 110 version comes with GPU Sandboxing on Windows
Security
Let's review: a Sandbox is used to isolate a process, so a virus or malware will not be able to directly use a process in order to attack other processes; so it will be more difficult, because it has to leave the Sandbox to achieve its goals of attacks on the computer or server. .
But it is not the first time that Firefox incorporates the concept of Sandbox; as for example in the socket and content processes.
History
GPU Sandboxing has already had its several years of development and this news is an achievement for this famous browser, because it has been criticized for the way it had been using sandboxing.
.Here you can see a history of the issue that started on March 15, 2017.
Challenges
According to bugzilla a problem is being worked on that is related to the file system, so the firstly the sandobox will not be so secure, as most likely you will have full access to the file system.
As soon as the problem is solved in future versions, full access to the files will be removed, so the sandbox will be providing the expected security.
