How does Firefox 4 improve memory use?
One of the items that bugged many people about Firefox 4, until very recently, was its use of memory.
That is, Firefox 4 (to put it politely) was a memory hog.
That's no longer the case as the browser is set to exit development and become generally available on March 22.
"Beta 11 revealed a method JIT which is part of
reclaim memory from object chains that get created by web pages," Mike Beltzner, director of Firefox at Mozilla told me. "Beta 12 fixed a
lot of that."
It sure did.
Fixing that one leak alone, isn't the only way that Mozilla developers have improved memory management and usage in Firefox 4.
