As a longtime user of Firefox, I couldn't pass up the opportunity to use a 64-bit version of it. I figured I'd give it a try and it's something I've been thinking of doing since I first used Windows Vista Ultimate x64. I honestly never heard of Waterfox until I read this article on Neowin. I installed it on my main PC (Windows 7 Ultimate x64) and I really like it. It definitely feels speedier than the standard 32-bit version of Firefox and things like Flash also feel faster. Another positive thing is that YouTube videos no longer crash my display driver. I assume that using a 64-bit version of Flash had something to do with it.

Anyway, if you have a 64-bit operating system and are open to the idea of using a 64-bit browser than Waterfox is for you. You can download it here alongside its prerequisites.

FAQ:

What is Waterfox?

Waterfox is a high performance browser based on the Mozilla Firefox source code. Made specifically for 64-Bit systems, Waterfox has one thing in mind: speed.

Why should I use a 64-Bit version of Firefox?

For some people with older systems, the 64-Bit version loads quicker and is much more responsive than the 32-Bit build. For people with newer systems, it allows them to use the full potential of their systems.

If there are any bugs, where should I report them?

Unfortunately, since this is a 3rd party build you cannot report any bugs and you?ll just have to hope that they get fixed in the next update by Mozilla.

Is my experience limited if I use a 64-Bit version of Firefox?

The major plugins such as Adobe Flash, Sun Java, Microsoft Silverlight all have supported 64-Bit binaries available.

How does it compare to 32-Bit Firefox?

In benchmarks, the 64-Bit variant of Firefox out-performs the 32-Bit variant. Also because this variant is being built specifically for Windows, there might be further performance increases.

Were there any optimisations made?

Yes, Waterfox was compiled with SSE, SSE2, x64 favoring and the following optimisation flags: /Og /Oi /Ot /Oy /Ob2 /Gs /GF /Gy

Do all my Add-Ons work?

Yes! Add-Ons work on any version of Firefox, on any platform.

I get a msvcr100.dll is missing error.

You must have the Visual C++ Redistributable file linked in the download page installed.

How do I fix the blurry font?

Type about:config in the address bar. In the filter at the top type gfx.direct2d.disabled. Change it from false to true.

I've always wondered just how they produce these 64bit builds, since for a long time the main codebase wasn't 64bit safe. Currently 64bit builds are still slower at JS than 32bit builds, and no amount of compiler optimisations will fix that.

Mozilla still don't consider the 64bit builds ready for anything but developer usage, they still crash randomly and often crash in such a way that the OS never calls their crash handling code (So the bugs go unreported)

I guess that was the case in the past. I haven't tried the 64-bit Nightly builds so I don't know how stable they are over the 32-bit Nightly builds. So far though, Waterfox hasn't crashed once. Perhaps Mozilla finally got around to making Firefox 64-bit friendly.

I still think Mozilla needs to kill the current code and start from scratch.

Agreed, especially with Google having such a nice clean product as Chrome.

Considering it's withstood the competition quite well, I'm guessing a lot of people would disagree with you.

I'd prefer it if Firefox was optimized for SSE2 like Chrome is, but it's not really a concern if the performance is there. (The 64 bit version will be, of course, since all x64 procs have SSE2.)

Quite a lot of snakeoil and even a surprisingly outright lie, in fact. It is designed in hardware so that x86 code takes zero performance hit when run on an x64 machine. None, period.

As for optimization, setting compiler flags can do little magic if the code is not applicable for it. I would guess that forcing the matter can even make it slower as the dedicated instructions become efficient only when used properly.

As for compatibility improvements that are at least evident, I've, for one, settled for Nightly (and temporarily the latest Tracemonkey if it decides to crash).

I've had Waterfox, Palemoon and Aya... whatwasit for some time, run lenghty benches, too. Results were inconclusive but not something to make an impression that either was better than the other. It is no question that both Chrome and Oprah is faster in most cases. Even IE9 holds up in certain test cases.

All in all, if it works for you, good. If it doesn't, however, better be sure that those loud promises of these custom compiles being the fastest and whatnot are full of very big holes.

It's disappointing to me that the Firefox devs are still waffling over how to do it properly.

Like, we know what we need to do this, and we are making plans to do it, but we don't actually want to do it.

Heh.

They're working on it (see here). Unfortunately, it isn't a high-priority feature.

Even up to the mid point of 2011 they still had random chunks of code that assumed 32bit OSs (Converting pointers to 32bit integer, etc.). As for the article, that's entirely made up, what I think happened is that somebody noticed Mozilla was running 64bit regression tests, and assumed that meant an official release was coming (Which it isn't for a while until they sort all the problems out)

I still think Mozilla needs to kill the current code and start from scratch.

There's no reason to do that, the incremental upgrades they're doing now are much better (Stopping the project for a year to rewrite vs. rewriting a component incrementally over a couple of releases)

It already is.

Have been using waterfox for the last few weeks so far and absolutely no problems whatsoever (same with firefox), constantly kept open for about 10 hours a day and memory usage always around 450MB (high res image threads, about 1GB then).

It is a wee bit more snappier and smooth than firefox 10 I find.

Been using x64 nightly for months now and has been as stable as the x32 builds sharing almost all the same bugs. No reason not to use it especially now that flash has an x64 plugin.

Well, you say that, but it doesn't explain the devs discussing it as if it isn't used much over here http://groups.google...=64-bit&lnk=ol

The only discussion I can see is about having less code paths (Firefox includes SSE optimised code paths and normal paths, a native 64bit build doesn't need the normal code paths since it can guarantee the CPU can do SSE). And as a side effect it also means the compiler can include SSE functions anywhere, not just in optimised areas (As is done currently due to how compilers work)

Edit: So the question is "Can we use SSE everywhere?" not "Can we use SSE?"

Been using Waterfox for a while now. Even if it's built by Mozilla, it's NOT Firefox, so it has to be better!! Have NEVER liked Firefox.

Can't say as I've never noticed it being any faster than any other browser. All browsers runs blazingly fast on my sytems and the day that some one says about how slow a browser is on their systems, is the day I should go over and fix their computer!

Palemoon, http://www.palemoon.org/ also has a 64bit version, but I use the 32bit version of that on my 32bit machines.

As far as Chrome, if I were to ever use that again, which isn't happening, it would be SRWare Iron, NOT Google Chrome crap!!

What about the Windows Media Player plug-in?

Unfortunately, 32-bit plugins won't work with Waterfox. It's up to Microsoft to release a 64-bit version of the WMP plugin. So far though, the major plugins work: Flash, Java, and Silverlight.

And even the 32-bit plugin hasn't been updated for years, what's up with that!?

In 32bit code, since we have to explicitly think and do work about every place where we want to do SSE2, and since it's a performance/size compromise, we end up not doing it in many places.

So yes, I know they use it to some degree, but from what I can tell not much.

It's based on the Firefox source code so aside from being 64-bit, it's virtually identical to the official 32-bit version.

And even the 32-bit plugin hasn't been updated for years, what's up with that!?

That's one of the issues of using a 64-bit browser. If you use Firefox with a lot of plugins, then Waterfox may not be good. Fortunately, I only use a handful of plugins and most of them have 64-bit versions.

    • AltSendme 0.4.1 by Razvan Serea AltSendme is a minimal, cross-platform application designed for fast, secure, and private peer-to-peer file transfers. It allows users to send files or entire directories directly between devices without relying on cloud servers, accounts, or any personal information. Everything is encrypted end-to-end using modern protocols like QUIC and TLS 1.3, ensuring both strong security and low-latency performance. Transfers are verified with BLAKE3 for data integrity, and interrupted downloads automatically resume, making the experience reliable even on unstable connections. You can transfer anything—images, videos, documents, and more. Integrity checks are performed on both ends, so your files are automatically verified for correctness during both sending and receiving. AltSendme works seamlessly across local networks or long-distance links, capable of saturating multi-gigabit connections for extremely fast delivery. With built-in NAT traversal and encrypted relay fallback, it connects devices almost anywhere. The app integrates with the Sendme CLI and will soon support mobile and web platforms. Fully free and open-source, AltSendme offers a lightweight, privacy-first alternative to traditional cloud-based services, removing size limits, upload costs, and unnecessary data exposure. AltSendme 0.4.1 changelog: Release Highlights Self-hosted relays: Run your own iroh relay so transfers don't rely on public infrastructure. Includes a full deployment template in deploy/relay/ with Docker Compose for a VPS and configuration examples for production use. Fly.io support: One-click deploy template for Fly.io, including a quick-start config (fly.dev.toml) for testing without a custom domain, plus production setup with Let's Encrypt and your own hostname. Relay settings UI: New Settings → Network panel to choose how AltSendme connects: automatic public relays, custom self-hosted URLs (with optional auth token), or disabled. Test connections, verify latency, and see live relay status in the footer. Disable relays: Turn off relay servers entirely when you only need same-network transfers (e.g. LAN). Direct connections only. No relay hop required when devices can reach each other. Android graduates from beta: Android is now part of the regular release cycle alongside desktop. APKs ship with each version (universal, arm64, and armv7). Other improvements Private relay access control via shared auth token Relay fallback notifications when a custom relay is unreachable Broadcast mode toggle in sharing settings Android release build fixes (split-per-ABI APKs, universal APK preservation) UI polish: mobile safe-area insets, dropzone layout, transfer progress animation Bug fixes for minification-related serialization issues and system tray icon loading What's Changed feat(relay): add relay status functionality and settings UI (a120cdf) feat(relay): implement custom relay server configuration and verification (51276c7) feat(relay): add configuration for private relay access and enhance observability features (48fbabf) feat(relay): enhance relay URL validation, display connection status (d4fffa0) feat(relay): add RelayChangeGuard component and enhance relay-related translations (16ba514) feat(broadcast): add toggle setting for broadcast mode in sharing UI (ca6d977) fix(relay): correct QUIC discovery port, pin image, templatize fly.dev (52a2ba5) fix: More broken serialization due to minification (67491a9) fix(android): preserve true universal APK across per-ABI builds (e9f256f) fix(ui): conditional safe-area insets padding on mobile (1182f0e) refactor(transfer): CircularRing component animation fix (944572b) chore(android): drop x86 and x86_64 release APKs, keep universal+arm64+armv7 (34ada0b) Download: AltSendme 0.4.1 | ARM64 | ~9.0 MB (Open Source) Download: AltSendme for MacOS | Android Links: AltSendme Home Page | GitHub | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
    • You are mostly right about the ephemeral nature of it. As I mention in the article, if you dont add a second device or take a backup of your account before uninstalling it, then yes you will lose access to your account. That said, in terms of actual user experience when you sync multiple devices your message history carries across and there's also a Saved Messages chat like there is on Telegram to send messages and attachments between your installs. But yh, what you point out are correct and its not trying to emulate Messenger or Telegram.
    • OK so SearXNG is a meta search engine that you can install locally or use via a public instance. It scrapes other search engines which you choose and then sorts the results. Not as complicated as multiple relays
    • The only difference here is that you think you came up with these reasons. You didn't. These age old fearmongering lies (that were NEVER true) were funded by and the anger stoked by Putin through proxies like Farage (and later in the USA, Trump) and filtered down through the skinheads, Neonazis, etc. until it reached the uninformed, ignorant, and gullible -- never realizing they were being played for fools against their own best interests. Even now, despite all of the EVIDENCE proving that Brexit was a terrible mistake for ALL citizens of the UK and that its supporters were tricked by Putin's proxies into sabotaging their own nation, you're still here defending these well-known lies as if they were ever true. Not only are they not true. They NEVER were. So, when are you going to realize that you were lied to and actually get angry at the liars and charlatans who lied to you, instead of blaming the innocent people they lied to you about?
