I'm very happy with medium-wattage LED lights of that sort, although I tend to prefer fewer higher-wattage fixtures for which LED bulbs are still pricy. I've been putting them into new fixtures, but pretty much all my existing ones are still CFLs and will be until the presently-installed ones die. Hopefully 100W (or better yet 125W) equivalent daylight LED bulbs will be more affordable by then; if not I may look into some 2-into-1 splitters for the 60W.

I discovered something interesting with LED bulbs: the "bulb" is purely for diffusion. I broke the glass on a relatively expensive 75W bulb, and the LED elements in the bottom work just fine bare (indeed, they probably are better cooled without it.) Very nice change from incandescents (toast) or worse yet CFLs (where the paranoid-of-mercury sorts would freak out on a break.)

I am really hoping to get my roof insulated in the next few years and when that's done, get solar panels. At ~35c per marginal kilowatt hour (ones closer to baseline are cheaper but we're up around 200% already) solar will pay off pretty quickly.

Chrome and Firefox run tabs and windows the same way (internally; there are differences between Chrome and Firefox and how they handle process isolation) Both won't (normally) ever run a whole second instance, although they can be subverted to do so.

Try Process Explorer (from Microsoft) : https://technet.microsoft.com/en-us/...sexplorer.aspx although I'm not sure it will give the specific additional information you want, it's pretty much the most detailed view of what's running available.
