>Please DO process-per-tab. I have a lot of memory. I want you to use it.

I hope that you ask them to add it as an option instead of replacing the current model. Firefox already uses my 8GB memory quite easily when I have many tabs open.

It is available as an option. "dom.ipc.processCount" in about:config allows you to set the maximum number of processes that it'll use. Set it to something like 1000 and it'll use a separate process for each tab (unless you actually open up 1001 tabs).

They are also working on a UI for changing that max process count (don't think that's in Firefox 54, but I could be wrong), but that UI currently only offers values 1 through 7, as it's just really unlikely that a normal user would actually want to sacrifice their RAM like that.
