Multi-processor support coming for Firefox

So does this mean that Firefox will now consume 100% of my available CPU cores now, as well as 100% of my memory?

Only when running Flash.

Should be "multi-process", not "multi-processor".

A single (classic) process can use a single processor; multiple processes can use multiple processors.

I thought you could use a single process with multiple threads to run on multiple processors.

But we have had processes with multiple threads that enable concurrent calculation in a single process for quite some time now, haven't we?

Very true on all modern OS's. Has anyone here looked into the firefox source to see if they are using threads in a parallel way?

chrome and Chrome? They need to change the name of their UI.

Maybe Chrome needs to change the name of their browser.
