I've been using
Chrome on our household's newer more quirky 8.1 system today.
I kept
essentially the same, or substituted some for similar, security extensions discussed & also added onto Firefox for both
XP &
Windows 7 systems.
With Chrome, I chose
Adblock (Adblock plus on Firefox),
Ghostery, HTTPS Everywhere (beta release),
Lastpass, Scriptblock (filling the absence of NoScript), &
WOT.
Scriptblock is relatively new for Chrome. It's straightforward setting it to remember to
Allow, Block, or Temporarily Allow scripts, & works very smoothly! I recommend it.
Browsing with Win 8.1 initially feels more responsive with the latest
Chrome in comparison with our latest released Firefox. The opposite has been true on the
tried & true XP sp 3 where
Chrome's greater demand on resources led me to choose to replace it with
Comodo Dragon which feels lighter, faster, yet nearly identical, albeit shall need to catch up with Chrome's update patches
..forever.
Humbly, IMO, browsing w/
Sandboxie makes up for this. I think
Opera/Chromium/under
Blink shall continue to have less extensions than available for
Chrome. I think I favor Comodo's alternative offering,
Ice Dragon, to Firefox on our Windows 7 (
stable Dragon stable); and so installed
Comodo Dragon there too!
