The multiprocess feature was one of the main reasons, I switched to Chrome in the first place. I think, it is just a good idea to keep the things separated, so one tab can not stop the whole browser.

Today, the browser more and more becomes that, which was called "operating system" some years ago. Many applications today run just from the browser and instead of switching apps, you switch the tabs....

So, it is just a good idea in my opinion to upgrade the security of the browser to a higher level.

I am not sure about the memory consumption, but since Chrome seems to have solved this topic, also Firefox should be able to, and maybe it's also time for me to switch back?
