This feels similar to some of the ideas I have already seen, so if it's been done someone can point me. (MilesAhead, your stuff is ringing a bell but this feels just a hair different.)
I Do "multi-batching" of my web pages with X topical tabs on an instance, and then Y more topical tabs on a new instance, producing two items on my task bar consisting of two copies of (currently Firefox but later someone can expand this) with batched tabs according to whatever project I am working on at the moment.
I would like to be able to save something like a Firefox Icon (named as needed) that would then produce one new instance with those tabs loaded. Important: *Not* to call up any existing instance and "smash the new tabs onto it". (That tends to happen on some sites I visit.) So for example when I click the raw Firefox Icon, I get a new instance, so just have the utility have previously analyzed what sites were loaded, then just reload them.
