I travel to two different locations a few times a year. I use the same basic "computer" for each one, though they're far apart. It works through a "sneaker network," where data files, profiles, etc, are copied to a portable hard drive and then copied to the next computer, so they're fairly identical. The problem is that this last time (and I've been doing this for perhaps about 3 years), Firefox has refused to do anything online. I can use it offline, but not online. The "work online" is unchecked, so it should be online. But it refuses to do anything. After several Firefox reboots, windows reboots, checking everything, Firefox still does nothing. Currently I'm using Waterfox and Edge. Both work fine. Thunderbird works fine. I've had this problem since Tuesday night. So about 48 hours now, and nothing at all. The way I transfer from one computer to another without losing email or current Firefox status is to copy the newest profile over, delete the old, and then copy the current program, as well. Thus, the program is up to date, as is the profile, but all I get when I type in any address is that dot thing at the top, going side to side. Thank you in advance.
