I really feel dumb but I did solve the problem. I remembered that just before the malfunction of Chrome I had installed adblock plus for android. So I uninstalled it. Having done that Chrome said the proxy server connection failed. My weather apps didn't work and Firefox said it couldn't find the proxy server. Well, I had no idea where to find the proxy server either, of course. Hoping for some information I went to the adblock site and found the installation directions. As directed I had modified the network. Undoing that solved my problems with all the apps including Chrome. I thought my sad story might help another newbie like myself. Be careful if you install adblock plus.
