I show both 66.0.4 the latest 64bit version, which my computer is 64 bit. I also show 66.0.3 which is a 32 bit version that I don't want on this computer. How do I get rid of the one, and stop it from reloading or updating and keep the 64 bit version only. It seems that I've had nothing but trouble with Firefox the last week or so. First you just out of the blue disabled some of my extensions.Without warning. No thanks to you I got them back. And was ready to stop using Firefox after being with you for over 20 years. Then trying to log in to this page, I kept getting and error saying that both the username and password are case sensitive. I figured that out also but not without some intense web searching.
