Description
Loading a simple profile from a file in Chrome or Safari waits for five seconds for a reply to the WebChannel status message. We added the wait for the WebChannel on the file loading path in #3501, in order to allow symbolicating profiles from files with the help of the browser.
We can skip the WebChannel connection attempt if the userAgent does not contain Firefox.
