HI hirenloong, I am sorry to hear that Firefox is slow on starting up. It sounds like you "Restore tabs from last time" and that there are 50 or more? https://support.mozilla.org/en-US/kb/firefox-takes-long-time-start-up
Please make sure that after the update that the antivirus is allowing Firefox to make the connections to those old tabs. http://kb.mozillazine.org/Firewalls
Please post back with your troubleshooting results.
