GMAIL OAuth problem. Does not open OAuth window without closing existing browser session.

GMAIL OAuth authentication window would not open when adding new account.   I had an existing firefox browser session running.  eM client was just waiting forever for OAuth window that would not open.  I had to close down the firefox browser, and then the eM client opened a new firefox session automatically and opened the OAuth window.  This is a bug!  the eM client should have opened a new window in the existing firefox session.  It took me almost 30 minutes to figure out that I had to close my existing firefox browser.  eM version 7.2.34062.0
