Setting up browser profiles for privacy work but realized I never verified the fingerprint isolation actually works.

My current testing:

1. Run browserleaks.com in Profile A - record Canvas hash, WebGL renderer

2. 2. Run same in Profile B

3. 3. Check if values overlap

Questions for the community:

• Are there automated test suites for fingerprint isolation?

• - What's the most important vector to check first?

• - Does AudioContext fingerprinting actually matter in practice?

Tested FireKey (app.firekey.ai) which claims hardware-level spoofing - cross-profile Canvas/WebGL hashes were different. But curious what systematic verification others use.
