I'll keep this very short and to the point. If you're a Firefox user from way back and use a Mac desktop, you need this. Runs well (very well, in fact), and all of your old add-ons work. I'm unsure why it's so under the radar, as I wish I would have discovered it a year ago instead of mucking around with ESR.

This version has been out for 20 days or so, so this isn't just a first impression. The new icon really looks like a blue fox urinating. I understand that Alex really needs to change the icon, so maybe he can have a "Make My Icon" contest or something. Speaking of which, boy does this thing piss away memory. It launches using a not great but acceptable half gig, but after a day of average usage, it's usually sucking up triple that amount. And, say I wanted to have a baseball game running in the background while I did something more productive. I'm just kidding. That wouldn't be possible with Waterfox. If I tried to switch to another app I'd be looking at a beachball for ten minutes, I can't even imagine what it would be like to try to work while it was playing video.. So unfortunately, Waterfox seems to be outgrowing me at a pretty rapid pace, and I'm constantly forced to use my backup of Opera even though I hate the layout, and I know it's probably logging every move I make, I just need that 1.5 gb of memory for other things.

After Mozilla's grotesque blunder with addons expired certificates, Waterfox confirmed its benefits as a solid and reliable browser. As for the future, news are pretty good: the next big version should continue putting together what is/was good in Firefox, some old extensions are even being updated, as mentioned in the release notes: https://www.waterfox.net/blog/waterfox-56.2.10-release-download/ I salute Mr Alex's dedication to his project and feel more confident than ever about this great successor to Firefox! :-)

Since my precedent review, I had issues with Chromium on some sites, so Waterfox came back to be my main browser, even if Chromium is faster. But moving forward, some XUL extensions started to have issues: MAFF stopped working, FEBE too, now Cookiebro seems to go the same path... XUL support was the main reason why I switched from Firefox Quantum to Waterfox and, though I've achieved a viable Firefox UI through a combination of userChrome.css and theme, plus various tricks to restore my workflow, I still have issues (in particular, the version of 1Password for FFQ won't work with all my other browsers, while an old version works everywhere except for FFQ! :-/ ) The next version of Waterfox is cooking (based on FF68 ESR) and it's very likely that it will break a lot of things. At that point, the gap between Waterfox and Firefox might only be about privacy — which you can achieve with a bunch of addons and tweaks in Firefox, so... Wait and see. ;-)

Cookiebro finally had an update that makes it appear again in Waterfox! I was convinced it was the browser's guilt instead, as the error was only present in WFx not in FFx... :-o

WTF 56.2.4 is out. Time for a small review. :-) Now that FF Quantum has gone away from me and my use case, I'm still using the last version of Chromium running on OS 10.9 as my main browser, but this will probably change as it's not being updated anymore for that system. Now, I coud call WTF "the old faithful" as it is slowly evolving, integrating security patches from FF, but keeping what I liked in old FF. No doubt it will take the place of Chromium for me, sooner or later. In the meantime, it's my safe choice when Chromium is not satisfactory or buggy on some site.

Jeez, I didn't even know this browser existed until today. I'm glad I found it. I like the older tab style, and it seems to run smoother than the more current version of FF. It's also easy on the CPU (so far, at least). I'm not into using a lot of add-ons, but that seems a nice bonus for other users.

Welcome! :-)
Yeah, extensions can become addictive... :-D
I've got little more than 30 of them enabled! Of course, I could live without many of them but it's like an old pair of shoes that makes you feel so comfortable. ;-)
Essential ones:
- Decentraleyes
- uBlock Origin
- uMatrix

Cosmetics or useful ones that I really like:
- Classic Theme Restorer
- Don't track me Google
- Google Analytics Blocker
- F.B. Purity (Cleans up Facebook)
- Keychain Services Integration
- Mozilla Archive Format
- Stylus

I miss a good Dark mode, though, such as Deluminate on Chrome/Chromium (I use Owl, after having had issues with Night Mode Pro — plus Stylus for specific sites such as... MacUpdate!)

After FF Quantum arrived, Chromium progressively became my main browser, but being somewhat experimental, there's always some site that makes me come back to another browser and Waterfox is really my best choice. In rare cases, I launch FF 52ESR or FF 60ESR, rather for checking or seeing how it evolves, in the latter case: for the time being, I can't see enough benefit in FF60ESR, compared to what I'd lose (including my current password manager, which is a fundamental part of my workflow).

It's true that not all old addons work but the vast majority of them do.
I'm currently running 31 of them, add 20 more that I fire up when I need them (such as Video DownloadHelper ;-) ).
Now that Firefox 52ESR is coming to its end, Waterfox will be the only option left, anyway,
Instead, don't forget that a lot of old XUL addons have been updated for FF56, so if you stick to FF52ESR you'll have to use non-updated versions. ;-)

Not much to add to my former reviews... ;-) It keeps working perfectly, it runs old XUL addons together with new webextensions (just what Firefox should have done!) and keeps the classic look of old Firefox. I regularly test current Firefox (60 at the time of this writing) and I can't see any good reason to abandon my old habits as it's not even faster — at least on my machine (some say it's faster on recent macs...) The promise of future development is quite enthralling as they plan to incorporate the latest enhancements of Firefox (Multiprocess even with classic add-ons?)

While I'm still using Firefox 52 ESR, I frequently run Waterfox and I consider more and more using it for a number of reasons:
- it IS Firefox 56 while FF52ESR has only its security fixes, so...
- ... many extensions can't update in FF52 while they can in WTF56
- it keeps the XUL extensions working
- it keeps the Classic interface (not 'butt-ugly' FF57+ ;-) )
- it's supposed to be less 'telemetric' than Firefox
To be fair, there are a few uncertain things about it, though:
- addons.mozilla.org recognizes it as being Firefox 50.0! :-o
- some extensions that should work don't... (or not yet)
- it has not frequent updates (and no up to date blog to keep users informed about its development progress)
- it seems to rely on one single man, no one can tell if he will be able to keep up with the effort for years, for whatever reason...
Anyway, it's a very good choice, for the time being, especially for the old users reluctant to FF57+!

I like it better than Safari and chrome nonsense. It also works very well on older OS such as OSX 10.8 which is abandoned by firefox. So if you're running older OS this or seamonkey are your best bets. Seamonkey has email built in but is much slower to upgrade.

After trying a bunch of sites, the current version (55.1.0.1) seems to work perfectly. It took me time to find that localization doesn't work as in Firefox: it's a setting in the prefs! — strange enough, the languages are not sorted alphabetically, so I had to watch carefully until I found French... Importing a profile from FFx: apparently you only can do it on the first launch and it doesn't import everything. Copying the profile and editing profiles.ini doesn't work. I had to create a profile with the same name of my FFx profile then copy the old profile's contents into the new folder. It took a few launches for Waterfox to sort things out but in the end all seems to be working. The "ethical" search engine is a nice addition. For me, it will be when FF57 (or even Waterfox 57?) comes out that we'll see how they compare. Wait and see.

I've done a thorough test of WTF56 and nearly all is working ok.
Only had a few glitches with some extensions: CLEO didn't work at all, but FEBE worked ok, NoSquint Plus is a bit clunky. Mozilla Archive Format and some other don't work but according to the dev, they might in future releases...
As I need old versions of 1password and BookMacster (not updated for OS 10.9.5 — but whose extensions are working in Chromium!!!), it's a show stopper for me that they don't work neither in WTF56 nor in FF57 (the updated extensions don't recognize the old apps and vice versa...)
Of course, I can't blame it on Waterfox, which remains an interesting alternative to Firefox.
Oh! There's a big issue, though: importing bookmarks doesn't work at all! But the old trick of copying places.sqlite from my Firefox profile works. ;-) (actually, it also still works between FF45.9 ESR and FF57, they don't seem to have change that file's format)
In the end, it's nice to have a more recent version of Firefox that I can fire when I need it, but it doesn't solve my biggest issues with Firefox (and, all in all, Chromium does...)

Anyway, I've also tried Enpass as a replacement for 1password, very similar and free for basic needs like mine. I've also found a workaround for BookMacster, so in the end, I'm now using Waterfox
instead of FF45.9 ESR.
The nice thing is I can use FF whenever I like without messing up my profile, as they are separate.
Performance wise, there's not much difference between those two. FF57 instead is a bit speedier, but not that much (maximum 1s on heavy sites) — but the horrible square interface is repulsive...

Just FYI to other readers out there— Firefox for Mac is already 64-bit, and has been for quite a a few years now. Therefore, I’m not sure there’s a whole lot of advantage to running Waterfox on Mac over the regular mainstream Firefox. But there might be a few disadvantages. For example, being a down stream fork, any new features or (more importantly) security updates have to be incorporated into the Waterfox project before it's pushed out to us. Things are different on the Windows side of the fence, where this Waterfox project originated. Despite Windows being 64-bit since Vista, many (if not most) programs still run in 32-bit mode. For Windows, I admire and applaud Waterfox's efforts.

Chromium still loads webpages 3x faster for me. Yahoo mail took almost 2 minutes to load with this, but less than 20 seconds with Chromium. Perhaps the developers might consider an ultra lightweight, stripped-down, version in the future that is specifically designed for speed ... Just an idea ...

Not only is this Firefox clone compatible with Firefox itself but apparently it simply takes over your Fx Default personality folder and opens with all Extensions and Bookmarks plus the latest version of Flash already loaded. The only thing that differentiates Waterfox from Fx is that it's been tweaked to load and open pages a bit faster. If I had fewer Extensions its speed might improve. You may or may not find Wfx preferable to Fx, but it's easy to try out and see. Though I found no problems with it I'm knocking off one star just because for me it's not that much faster than Fx. But I'm going to continue to use it to see what future versions may bring.

SERIOUS SECOND THOUGHTS: When I wrote the above review I knew that Wfx was 64bit only but now discover that all but two of my Extensions - 1Password and Adobe Flash - have been disabled because only 64bit extensions will work on it.. The developer names only three Extensions that work on Wfx - Adobe Flash, Silverlight and Java (he doesn't mention 1Pwd but it does work.) Notice that all three the developer mentions are highly vulnerable to hackers. If this is good enough for you, try it out. But it's definitely not enough for me and I regret leaving even four stars for this browser without testing it thoroughly. Egg on my face but please ignore my rating. I'm deleting it.
