I have a laptop and a desktop.. both run the same Win 7, both run Firefox 49.02..
The laptop is pretty quick to load .. usually only a few seconds delay.. On the desktop.. the same page may NEVER load..
the little wheel icon just spins and I get timeout errors.. if it does load its a matter of minutes not seconds.
They are synced accounts with the same addons etc.. both work from the same WiFi router..
Can someone please help as its really frustrating to have to wait wait wait..
