Urquhart & alternaut:
Many thanks for pointing to possible Chrome standalone downloading sites. I'll glom onto a copy asap.
As for Flash Player: For obvious security reasons I'm leery of installing a standalone player. The only reason I have Shockwave Flash as an add-on in Firefox is because it's one of the few plugins that Mozilla has vetted for use with same. With Firefox Quantum most of my previous extensions and plugins are no longer supported by Firefox and were disabled; Firefox, on the other hand, improved its functionality and most of those older bits were no longer 'necessary'.
