I have to refresh Firefox every time I open it after previously closing it
Whenever I close down Firefox, it is then very slow to restart. When it does restart, pages are very (and I mean very!) slow to load. I have to go into help>troubleshooting and then refresh. This can take up to 5 minutes in total from first opening the browser. Once refreshed, all is well and performance is as slick as usual. Any ideas please? I am using a macbook pro running El Capitan 10.11.1 Firefox version 42.0
Thanks in advance!

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