From Jim H.
If you're occasionally on public wifi it is a good idea, in my opinion, to use a VPN for security reasons. The following article discusses the Vivaldi Browser, which now includes a free VN -- Proton. I have read elsewhere that Proton is a decent VPN, especially for free:

Some time back I tried the Vivaldi Browser, liked it OK, as I remember, but somehow got away from it. I may try
it again. Here is the download website, if you may have an interest also...Jim
