Windows 10: Firefox 64-bit is now available to download

I have used x64 versions of Seamonkey and Pale Moon since 2011, and since I have plenty of opportunity to compare x86 versions, I find it snappier and more responsive as well.

I never knew that IE 11 was sanboxed: really?
*Smile

 

Definitely snappier here too.

 

The rendering seems much quicker (snappier). I had been using IE11 because it was better at rendering (snappier). Probably ought to run some tests. Peacekeeper used to measure rendering speed, but that is defunct now.

 

I've been using x64 builds of FF for years now. There are nightlies, Pale Moon, and more recently betas. All of them have been rather stable and usable for me. I always keep a vanilla x86 FF for compatibility - sometimes I go overboard with security precautions and add-ons and then some sites get broken. As far as speed - once you get an SSD and a decent system, speed is no longer an issue. The benchmarks may argue about nanoseconds, but I certainly can't feel them in real life, so I never bother looking at benchmarks anymore.

As to the "advantage" - that was Mozilla's argument for years, they did not develop x64 FF since they did not see the advantage. My reason is that running anything 32bit on a 64bit OS requires the additional emulation layer and is simply unnatural, however well it might work. It also seems more secure, but just because the majority does not run it.

 

I downloaded and installed Cyberfox 64 bit...i never knew this alternative to Mozilla Firefox existed...anyway Cyberfox loads up faster..Mozilla Firefox add-ons i use are compatible....and Cyberfox does not crash as Mozilla Firefox does with Adobe Flash Player plugin.I could not watch Demand 5 catch up player at all...keep getting the Flash player plugin crashed message.

Since installing Cyberfox Demand 5,BBC iplayer,Itv player programs play perfectly as if you watching a dvd...quality is amazing...maybe it's something to do with my 64 Bit 8.1 OS i have along with 64 Bit AMD Graphic Driver.

I like it.Uninstalled Mozilla Firefox and never looked back.

 

Been using x64 builds for years as well. Never any real issues of note other than the typical bugs present in unstable software.

 

First time using the 64bit as well and I am quite surprised. Definitely snappier, all my addons still work (don't use many tho) and even adobe flash seems to be working fine

 

put ff 64 on desktop and had a few problems with it not responding
web page a bit slower to show
use pale moon 64 on here for awhile and no problems so far
don't use edge as my touch pad will not scroll but works alright on pale moon

 

Im a little lost here, Firefox 64bit has been out and supported for a long time now....Been using it for a long time now even before Windows 10 and the 64bit FF has been fine since the launch of Windows 10 as well. I guess this is why im a little confused on the thread. If im missing something, forgive me.

 

Only in nightly alpha and only recently developer builds. Not the mainstream product.

 

The official release of a non-beta version of Firefox 64 bit was with release 42. All the previous releases were either beta or alpha versions.

 

I tried 64 bit CyberFox and WaterFox in the past and really couldn't see any benefit to using them over 32 bit Firefox. I haven't tried the new 64 bit Firefox yet, but I did read about this new vulnerability:

Latest EMET Bypass Targets WoW64 Windows Subsystem | Threatpost | The first stop for security news

Getting away from the emulation layer may be enough reason to switch to a 64 bit browser.

 

If I am not misunderstanding this article,

If you use 32 bit software a lot, you should use 32 bit operating systems. If you use mostly 64 bit software then you should use 64 bit operating systems.

I thought 64 bit was suppose to protect your computer at boot time better then a 32 bit system.

I don't know if Linux is effected by this. A lot of people add wine, which runs some 32 & 16 bit software.

So, should you run windows 10 32 bit if you use mostly 32 bit software?

 

ff 64bit been a pain on desktop had to uninstall it was locking up the computer.
also had to uninstall 32bit as well as it was playing up now reinstalled 32bit and everything fine.
yet pale moon 64bit works alright.

 

I believe the move to 64 bit Windows was driven mainly by the desire to install/utilize more than four gigs of ram.

Kernel Patch Protection aka PatchGuard, is a feature of 64 bit versions of Windows and was first introduced with XP x64. Whether it's good or bad is hotly debated and needs a separate thread *Smile

Note that if you use a 32 bit operating system you will only be able to run 32 bit software.

I haven't studied the WoW64 vulnerability article yet. For the moment it makes sense to use 64 bit apps that are internet facing when possible.
