Long starting time...
The browser need often more than 1 or 2 minutes to start.
There is an earlier thread about this. .One or two minutes is exceptionally long. It should not be taking more than 10 or 15 seconds even after first switching on the computer, and maybe 5 seconds for some users. A warm restart should take 5 seconds or less.
Are you opening by restoring the previous session with lots of tabs?
Try turning off antivirus and firewall while disconnected from the Internet, and see if it loads any faster.
