Managing Browser Profiles when using Cross Browser testing in Coded UI Test

This post addresses specific challenges in managing browser profiles for cross-browser testing with Coded UI Test. It details two common issues: 1) when a profile is not picked up, providing solutions involving command-line arguments (`--user-data-dir`) and environment variables (`ChromeProfileDirectory`, `FireFoxProfileDirectory`), and 2) when multiple Chrome browser launches fail due to profile locking, explaining that Chrome's profile directory cannot be shared by multiple instances and suggesting workarounds like creating temporary copies of the profile folder. It also notes that Firefox handles this by copying profiles internally.
