User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID: 20170628075643 Steps to reproduce: Steps: 1. Login to Win-7 or Win-10 or MAC Sierra. 2. Open Firefox browser running latest version i.e. 54.0.1 3. Try doing anything else on system i.e. open Outlook, access folder, etc. Actual results: Observation: 1. As soon as Firefox comes up, Screen freezes and One can do nothing for a while say a minute or so. 2. If User starts opening up other applications or accessing folders, It leads to explorer crashing on windows and on MAC, One has to force quit or kill application and as last resort, restart the system. 3. But after sometime, say a minute or two, System becomes normal. Expected results: Expectation: 1. Ideally, Nothing should freeze and everything should work as It were. 2. Firefox older version were lighter around 20-24, Ok-Ok till 37-39
