After using Firefox for 30 minutes or longer Firefox slows and the cursor gets behind and jerky. Eventually will not respond and I have to reboot my iMac twice to clear the problems caused by Firefox. I have deleted all internet caches, cookies and web content. I have done the recommended delete and update. It works for a day or two and then the problem starts over again. Firefox is definitely causing a problem and I am going to have to stop using it. Safari does not have these problems. iMac OS 10.12.6, Firefox 59.0.2.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Note: If you start to have any problem, Close Firefox.
