You misunderstand. They're calculating a fingerprint that identifies you across sessions despite you changing up a bunch of values on your browser with an extension because that's all highly detectable. They know it's junk data they don't use it. It actually is worse because you stop blending in with the crowd.
You're better off blending in then trying to look unique with every visit. The latter is a flawed concept.
Read the arkenfox guide they get into it. Most extensions just reduce your ability to blend in to the crowd and thus should be avoided.
If you're actually interested in reducing your fingerprint you should read the arkenfox guide which leverages built in features from firefox. You'll see very quickly that if someone wants to fingerprint you it's trivial and there's little you can do short of TOR.
Librewolf/mule is essentially pre-packaged Firefox w/arkenfox and some things stripped out.
The devs work informally on it which is why some releases lag. Like the jump to v128 lagged on mule because Firefox switched the way their repo worked and mull is based off of the Firefox source with some build scripts to change the logo, branding and add arkenfox settings by default.
The flags used by Arkenfox are largely funded by the tor project as they work to upstream many of the tor browser changes back into Firefox which enables efficiency for future tor builds.
This benefits everyone as the privacy preserving features of tor can be used off of the tor network too.
"The feature automatically locks your phone when it detects your phone has been snatched from your hand. It uses data from your phone's accelerometer and gyroscope"
Look I'm fine if the govt wants to say a particular corporation is too big to fail. But trying to let that company remain private is not how too big to fail works. If you want a bailout, the govt owns your company, and the govt is obliged to maintain ownership for as long as it's deemed too big to fail...e.g. critical to national interests.
You'd be surprised maybe how many developers don't properly remove all files they put on your computer. Adobe is notorious for this.
