FIREFOX gets stuck

[nunof32]

Hello,

macOS High Sierra 10.13.4. Firefox 60.0

Following yesterday's installation of last version (60.0) I have a problem with Firefox on one - and only one - of the accounts on my MAC : when I launch Firefox the home page displays ok, the first site I access displays ok but from then onwards nothing else responds : Firefox is really stuck.

I have alreday tried to clean the cache, recover previous sessions, but the problem persists. Is there a file created and used by Firefox, specific to this account, that I must get rid of in order to unblock the situation ? (I suppose I can also re-install Firefox from scratch on my computer but how do I make sure there is no spurious file left around that will make the problem persist ?).

Thanks for any help available.

Used Refresh Firefox feature. Situation seems now back to normal.
