NEW Nightly Firefox Win 64 bit Discussion

[ferongr]

64 bit Firefox is more secure because of the (much) more memory addresses that can be used for ASLR.

Please provide proof on that. A partial attack against ASLR on 32bit binaries is this and it requires too many conditions to succeed.

[Ver Greeneyes]

There are some other advantages to having a lot of address space. For instance, 64-bit OdinMonkey maps 4 GiB of contiguous address space to put all its addresses in, which it therefore knows won't be used by anything else. I forget the exact details, but having 4 GiB of addresses all to itself helps it make some optimizations.

That statement is partially true. 64-bit has more addresses to randomize.

Windows in particular has a few security tricks available only on 64-bit versions.

do you think it matters more when a drop fall into a lake than in an ocean?

[kronckew]

it used to take many cells in a sample to process DNA at the crime labs. now they can do it with one hair.

the lake is shrinking steadily. some people want to be prepared for the drought.

[Grantius]

That may be, but I want as much as possible to use only 64bit software.
And since it is very annoying that Mozilla now no 64-bit Firefox offers.

Is it because 64bit is a bigger number or is there another reason why, say, VLC needs to use more then 4GB of RAM?

I use a 64 bit operating system and I want to use 64bit software on it, that's all.

What if it was slower than the 32bit software?

[Virtual_ManPL]

simply... devs will need to fix a regression
because 64bit need to be the same as 32bit in performance terms or even better...

[HeinzDo]

What if it was slower than the 32bit software?

I am now at work and there I have the 32-bit Firefox.
But a difference in the speed you can probably find only with tools.
I notice there is no difference when surfing.

You could always switch to Pale Moon or Waterfox.

This is NOT a discussion about third party builds please stop now

[Ver Greeneyes]

Besides, it's not like those unofficial builds wouldn't benefit from having an officially supported tier 1 64-bit Windows build. Just look at all the test failures that they're addressing to get things into a better state - there's no reason to think the unofficial builds don't suffer from the same problems (no matter how obscure they may be).

[HeinzDo]

I also only use the official builds.
Since 2002.
And I stand by it.
