Initial Load Timezone still detects home timezone #16

Pretty self explanatory.

I'm using latest version of Brave. I install app. I load up https://vytal.io , Initial Load Intl.DateTimeFormat().resolvedOptions().timeZone still detects the home timezone. This affects all of the other time related detections on the site as well.

40 seconds after I posted this, I figured out the solution.

If on Brave Shields, Block Fingerprinting is enabled, then this issue happens. Allowing fingerprinting allows for the full spoof to work.

Disable Brave Shield Anti-fingerprinting

Does it happen only on the first load of a tab? There is a slight delay between when a new tab is opened and the debugger starts mocking the data. This allows for websites to get the original value of the data before it is changed. After the initial loading of a tab, this will no longer be an issue.

it only mocks my initial load after the refresh, no matter if I wait for a few seconds after turning on vytal or go to the website right after. vytal also doesn't have to be recently turned on to make this issue occur, even if you have been running vytal for minutes and go to vytal io it can still detect my initial load, but if I refresh then it fixes.

@Z3R013x Are you opening vytal in a new tab tho? Is it possible for you to record a video? Thanks

Z3R013x commented 2 years ago

I'm turning on vytal while i'm on "new tab" page and then navigate to vytal.io

z0ccc commented 2 years ago

A new tab has to be initialized on an actually url, not a chrome page (like the default new tab page). Looking for ways to improve this and possibly fix the whole initialization issue.

Let me share video with you on mail. just to be clear.
