I just installed Librewolf today, using it now. Being a fork of FF it makes a very smooth transition.

I use a similar set up. Librewolf on Linux and IronFox on Android. You could still use a Firefox account to sync, but I wouldn’t. I’ve heard there’s a way to host an older version of Firefox sync locally, but I haven’t looked into it.

LibreWolf finally has an account at mastodon @librewolf@chaos.social

If you want to keep the Gecko Engine from Mozilla to support an alternative to Google's monopoly here are a couple alternative for Linux :

• Librewolf
• Mullvad Browser
• Zen Browser

For Android you have to be aware that unfortunately every firefox based browser lack of per-site isolation unlike chromium browsers.

• IronFox (active fork of Mull by DivestOS)
• Fennec

On the dark side of the spectrum you have chromium browser such as :

• Brave (Linux & Android) (disable cryptocrap, sponsor backgrounds and it's quite good)
• Cromite (Android)

I've been using LibraWolf on desktop for several years now. It's just far simpler than modifying standard Firefox. for my personal needs.

https://digdeeper.club/articles/browsers.xhtml has a somewhat comprehensive analysis of a dozen of the browsers you might consider, illuminating depressing (and sometimes surprising) privacy problems with literally all of them.

In the end it absurdly recommends something which forked from Firefox a very long time ago, which is obviously not a reasonable choice from a security standpoint. I don't have a good recommendation, but I definitely don't agree with that article's conclusion: privacy features are pointless if your browser is trivially vulnerable to exploits for a plethora of old bugs, which will inevitably be the case for a volunteer-run project that diverged from Firefox a long time ago and thus cannot benefit from Mozilla's security fixes in each new release.

However, despite its ridiculous conclusion, that page's analysis could still be helpful when you're deciding which of the terrible options to pick.

Floorp and librewolf, among others.

Ironfox on Android, easily is the best.

LibreWolf is what I use, but I heard Zen Browser is another fork that's been getting some traction. I don't use it though, but I've heard from someone who does that it works for them. thumbs-up

So I haven't been following the Firefox thing that closely. Fennec isn't an alternative because it uses Firefox's Sync and Brave is out of the question because it's crypto Chrome?

librewolf, mullvad, zen browser? all fork of firefox

Depends on your specific case, but IMO in order of preference for deskop, Tor Browser as much as possible, followed by Mullvad Browser as much as you can, for scenarios where you cannot use Tor Browser, followed by LibreWolf for the few sites that require persistent logins (you'll need to enable setting cookies for those specific sites). There's also other Firefox forks like GNU IceCat (unofficial binary for it), Floorp and Zen Browser.

For a less complicated alternative, just swap out Firefox with LibreWolf. Just make sure to read the ENTIRE docs to save yourself from any nasty surprises. Especially about RFP (Resist Fingerprinting), WebGL, Canvas, etc.

On Andriod, again, there's Tor Browser, IronFox, Fennec F-Driod. Additionally if you want a browser based on a different engine, there's Cromite, which is based off of Chromium, but it's probably better to stay with a less commonly used engine like Firefox rather than keep using the mainstream monopoly of Google.

As an aside, this video helped me understand some stuff better and it seems to be less of Mozilla being untrustworthy and more about them being total losers in communication. I recommend checking it out.

Use any fork of Firefox without the sync option.

Zen browser is very good.

Floorp :)
