FireFox 64-bit?

Hi. I'm at my limit with the 32-bit I'm using. I don't see any 64-bit out. What's the deal? Is there any possible hope for a 64-bit version?

The reason I'm asking this is because FireFox doesn't seem to fully take advantage of my RAM. I have 32GB 2400Mhz DDR3 and I have over 300 tabs and I'm using an addon that actually unloads tabs that are not in use or if they're not used within the past hour. So that helps, but FireFox crashes everytime. Even new fresh installation doesn't help or moving them over to a different computer doesn't help either. To my understanding, the latest version of FireFox has a maximum amount of RAM that it can use so I can only guess that it's 32-bit version.

Unless I'm wrong, please correct me. Don't ask what I use the tabs for. That's just what I do. My systerm is super beefed up so clearly that isn't the issue here.

Note that you are referring to 64-bit Windows only as there has been 64-bit for Mac OSX (combined 32/64) and 64-bit along with 32-bit for Linux since Firefox 4.0 from mozilla.org

Since the Win32 Firefox worked fine and there were a number of technical hurdles that needed to be done to get to Release it was made a lesser priority compared to other things in meantime. If it was the case of needing Win64 Firefox in order to use Firefox on 64-bit Windows then it would have been a top priority.


There is actually some work going on in have Win64 for Release as early as Firefox 37.0. Technically Mozilla could build Win64 Release now but would it be stable and a good idea, no.

From http://forums.mozillazine.org/viewtopic.php?f=23&t=2876519 Mozilla plans to roll out the 64-bit in phases:

Phase 1: A separate 64-bit installer is provided and users are informed about it on the browser's what's new page. 64-bit builds are served from that moment on to users who opted-in. The majority of plugins and binary <strike>add-ons</strike> Extensions won't work in this phase. Phase 2: A universal installer that supports both 32-bit and 64-bit. Flash support is provided either via 64-bit Flash or Shumway, and <strike>add-on</strike> Extensions support is improved. Phase 3: Auto-update functionality.

The proposed version of Firefox for phase 1 is Firefox 37 Stable.

Correction as Addons does not mean one thing as it is a general word that groups together Plugins, Extensions, Themes (both real complete and images aka lightweight), dictionaries, search engines.
