I tried and tested, it appears in osticket (default installation), some of the tabs are not working well in some browsers.
So far I found MS edge have no issue, but I have issue with firefox, brave, even chrome at time.
Say under agent view and I'm at staff.php?id=1#account, I can't browse to scp/staff.php?id=1#access or staff.php?id=1#permissions
Is it known issue?
