Firefox preventing PC going into sleep mode

From about the time I installed Dropbox 2-3 weeks ago my Windows 10 PC won't go into sleep mode unless I close Firefox first. Closing Dropbox makes no difference so it might just be co-incidence. If I use Norton to run a scan and go into sleep mode at end that also works, and PC stays asleep until I wake it. Have tried refreshing Firefox but no improvement (running Firefox 91.0.2 (64bit)). Any thoughts please?

Chosen solution

After 48 hrs the problem seems to have been resolved. The actions I took that may have contributed and which might help others with a similar problem :- 1) cleared all history and cache, 2) refreshed Firefox, 3) logged out of Dropbox (but logging back in hasn't brought the problem back)

Please note: Many have reported issues when their systems go into sleep mode when Firefox is running.
