So I ran the usual apps, CCleaner, malwarebytes, checked the add ons, deleted cache files, reinstalled my copy of Firefox...all of them were clean and no problems found.
Googled Firefox with Win 10 and there were lots of people apparently having the same symptoms. Tried a few of the top suggestions but had no luck at all.
Has anyone here had similar problems with Win 10 and Fx?
Any good insights as to what's happening?
BTW, I went back into Win 7 and all worked fine. Installed ver, 49 of Fx in a few minutes and OK.
Surfed around fine without any apparent sluggishness loading the sites.
