At an intermittent frequency between 10 seconds and minutes, Firefox will freeze and the cursor will spin. I've been turning add-ons on and off for weeks now. I've tried safe mode. The bug will only manifest after Firefox has been turned on for days, and I can't survive that long in safe mode without LastPass and uBlock. How do I diagnose this issue, because I'm going crazy.

Are these programs the same? Having more than one version of a program may cause issues.


Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?
