It turns out Google Chrome ships a default, hidden extension that allows code on `*.google.com` access to private APIs, including your current CPU usage
You can test it out by pasting the following into your Chrome DevTools console on any Google page:
chrome.runtime.sendMessage(
"nkeimhogjdpnpccoofpliimaahmaaome",
{ method: "cpu.getInfo" },
(response) => {
console.log(JSON.stringify(response, null, 2));
},
);

What functionality would I lose/gain if I switch from Firefox to Librewolf? I’m admittedly an amateur in the privacy space, and I’ve been pretty content with Firefox + Ublock and container tabs for different profiles, but I consistently get the issue that my browser fingerprint is pretty unique, and I have no idea how to or even if I can anonymize that anymore.
Librewolf is not associated with Mozilla and does not receive their primary source of funding from Google like Mozilla does.
I really like having the same browser and browser synchronization between my phone and desktop/laptop, so librewolf is out for me. They have no interest or resources to build an Android version. Waterfox does at least have desktop / android option and takes things at least one small step further away from Google.
It is the same browser. LibreWolf doesn’t change much of the Firefox code, mostly just the configuration. They enable various privacy/security settings by default and remove Mozilla telemetry. You can go to the LibreWolf settings and enable Firefox Sync, and it will work just fine with your Mozilla account and other Firefox browsers.
For Android, I like to use Mull, it’s a hardened build of Firefox, similar to LibreWolf.
The previous answer is misleading and partially just wrong. Firefox Sync works just fine in LibreWolf, you just need to enable it in the settings. I currently sync my LibreWolf browser on my Linux desktop to Firefox on iOS and Mull on Android, no issues whatsoever. The only Mozilla services that LibreWolf intentionally removes are their telemetry and Pocket.
Tangent note: I think browser fingerprinting is only a source of concern if you use VPN. Otherwise, your IP is already a good enough identifier, and quite likely doesn’t rotate often enough. Please someone correct me if I’m wrong.
I appreciate the list. I’m not saying there aren’t valid concerns, just that in my day to day life it’s one of those items where the steps needed to avoid browser fingerprinting is usually more work than the value I personally get from my perspective.
I’ve looked into this, and I’m not clueless. I’ve developed websites, I’ve done a lot of stuff with Selenium / Puppeteer, and have toyed with Firefox browser extensions.
I understand the tools they use and it’s just very tricky to fully eliminate this type of thing. For example they can even use the browser window size. Are you going to randomly change window size to some novel dimension when you open up a tab?
What about the JS engine you use. For example using Firefox already narrows down your anonymity by like 95% or something because only a small amount of users use the browser. Etc etc
It’s hard to do this correctly, and I feel like VPN + private window usually takes care of the price fixing thing on the list, for example. When I’m searching for flights I usually do this.
I also use JS blockers in order to try and mess up the scripts that Facebook & Google have hidden over the internet to track you. But ironically, doing that again reduces your anonymity. They know that if their scripts don’t work on you, you get narrowed down again to a very small % of users.
It only takes a few of those pieces of data to be reasonably sure that it’s you. Browser fingerprinting is tricky to really avoid. It’s not impossible, of course. Just saying to really do it right it might be more effort than it’s worth.
The depth of fingerprinting really bothers me and I have accepted that the best at it will succeed.
It is tempting to find the world’s most popular default configuration and use that :) But that’s prob be something gross like Windows 10 & Chrome! In fact, that’d be second after Android & Chrome. Wonder how detectable VMing/emulating those configurations would be.
Agree with you and appreciate the detailed response!
It’s sort of legally gray but generally speaking in the US downloading is a civil offense but not a criminal one. You can get sued by the copyright holder for example but you won’t end up in jail over it.
People usually never get sued for it because it’s not worth it for Comcast to pay for lawyers to try and extract any money out of regular people. Not only will they almost certainly be unable to even recoup the lawyer fees, they risk getting a lot of bad PR for no gain.
What’s usually considered an arrestable offense is uploading aka distribution. Once you start hosting seedboxes then you enter the area where you’re liable to go to prison.
Switching from Firefox to Librewolf has some pros and cons. Librewolf is a fork of Firefox focused on privacy and security, with telemetry stripped out and privacy settings maxed out by default. You’ll gain better out-of-the-box privacy protections, meaning less tracking and data collection without having to tweak settings yourself.
However, you might lose some convenience. Librewolf might not support certain Firefox features like Sync, since it relies on Mozilla’s servers (not sure about that point, maybe it does work). It can also break some websites due to the stricter privacy settings. Another thing to consider is that you won’t get updates as quickly as Firefox.
Regarding browser fingerprinting, it’s a tricky beast. Librewolf can help somewhat by making your fingerprint less unique, but it’s not a silver bullet. Tools like uBlock Origin and container tabs are great, but adding something like the CanvasBlocker extension can also help reduce fingerprinting. Ultimately, no setup is perfect, but Librewolf is a solid step towards better privacy.
if it’s fingerprinting you care about, i’d give mullvad browser a try. it’s a firefox fork tailored to increase privacy and blend you into the crowd (as long as you don’t change any setting/install addons). it’s very very neat.

U can sync regular mobile ff and librewolf. Thats what i currently have.

Thanks for the answer! I run Windows, iOS and Linux across multiple devices, and sync is definitely needed for me as well. I’ll look into Waterfox!

Yeah I’d only worry about it if I were trying to buy drugs on the dark net or something. I guess if torrenting became illegal I would also worry.
I worry about price discrimination

No. If you don’t want to be tracked and you are using a VPN, fingerprinting is a problem as well. Privacy is not concern just for drug dealers.
Became? 🤔
Torrenting itself is not illegal. The distribution of copyrighted material that you don’t own is the illegal part.
Different places have different laws

Firefox sync is disabled by default but you can enable it in the settings.
I don’t really care too too much about privacy. If they get rid of the Pocket button then I’d be happy enough.
About:config
Extensions.pocket.enabled false
May I please steal this for future use?
I stole it too lol
Yes, why to do this?
if it’s fingerprinting you care about, i’d give mullvad browser a try. it’s a firefox fork tailored to increase privacy and blend you into the crowd (as long as you don’t change any setting/install addons). it’s very very neat.
Mostly it’s just FF but with more private defaults (that you can change in the settings trivially anyway), although there are one or two extras.
There is a potential issue, though. Librewolf runs behind, so security vulnerabilities, particularly for zero-day exploits, take longer to be patched.
