This concern of ShadowAce - I got tired of that with Firefox.I guess I would say that Chromeplus fills all my needs out of the box. I haven’t added any add-ons at all. I was forever messing around with them with Firefox.
“I lost a few extensions/add-ons when I upgraded from 3.6 to 5. How many might I lose upgrading to 6”
I honestly don't know which ones--if any--would be lost in the upgrade. I use several that seem to update themselves fairly quickly with each firefox update.
