Jira keeps jumping back

[Joe]

From time to time, when I go to another tab in my browser, then back to Jira, it goes 'back'.

Since I'm not 100% sure where to, I'm not going to claim I know.

Either a history.go(-1) type of back, or simply their own navigation path back - I've no idea.

However, the result is that it either closes the open ticket, or goes back to an earlier one.

It's mighty annoying, only started a month or two back.

Is there anything to do?

p.s.

this is not my main account.  I could not use that one to log in here, for some reason it claims to have sent the login code but it's not coming.  Yay for 2fa where it's absolutely unnecessary.

p.p.s 

due to the above I cannot start a support request either.
