> but when I look down the list 16/58 javascript attributes are red (the lowest category of similarity ratio) and only two of those are overtly dependent on a version number, another six refer to screen size/resolution. It seems to me that leaves quite a lot of information which isn't going to change all the quickly.
I disagree. Going through the list, the following attributes are basically 100% tied to the browser or browser version, because nobody is going to change them:
* User agent
* Accept
* Content encoding
* Upgrade Insecure Requests
* User agent
* Platform
* Cookies enabled
* Navigator properties
* BuildID
* Product
* Product sub
* Vendor
* Vendor sub
* Java enabled
* List of plugins (note that plugins were deprecated by major browsers years ago)
* Do Not Track (DNT has been deprecated in favor of GPC, and if you want to stay anonymous you should leave it as the default)
* Audio formats
* Audio context
* Frequency analyser
* Audio data
* Video formats
* Media devices
The following are very correlated to your geo ip, so unless you're pretending to be a Mongolian with a US geo IP, it reveals very little.
Content language
Timezone
Content language
These are actually valuable for fingerprinting, but most of these basically boil down to "what device you're using". If you're using an iPhone 16 running iOS 18.5, chances are most of the device related attributes will be the same as everyone else with an iPhone 16 on iOS 18.5.
Canvas
* List of fonts (JS)
* Use of Adblock
* Hardware concurrency
* Device memory
* WebGL Vendor
* WebGL Renderer
* WebGL Data
* WebGL Parameters
* Keyboard layout
These are basically screen dimensions but repeated several times:
* Screen width
* Screen height
* Screen depth
* Screen available top
* Screen available Left
* Screen available Height
* Screen available width
* Screen left
* Screen top
These are non-issues as long as you don't touch such settings, and are reset if you clear browsing data.
* Permissions
* Use of local storage
* Use of session storage
* Use of IndexedDB
These basically boil down to "whether you're using a phone, laptop, or desktop"
* Accelerometer
* Gyroscope
* Proximity sensor
* Battery
* Connection
The last few seem related to flash but since that's been deprecated years ago they're non-issues.
