Reply #5: Seems nice and fast. Ubuntu users can probably install it from the repository:

[struggle4progress]

that's how I installed it in latest Mint

Some webpages are problematic: www.google.com (for example)
can't be accessed unless you do something like

Edit >> Preferences >> Network

and then instruct to identify as Safari (say)

Behavior here is somewhat irregular and unpredictable and may
be affected by some cache I can't clear. I couldn't get into
Googleland, then I could get into some of Googleland but not
all of it, then I could get into any of it
