As I recall, T stands for Talos, which is the name of the Mozilla performance suite. TP5 is the 5th version of one particular benchmark which takes pages from the "current" eb (hence the need for new versions every few years). I guess 'P' is for performance, but I forget.
Actually, even that just used the Acronym without explanation.
I missed the link in the 'answer though'.
So 'after TP5' means after loading a manually curated list based on the top 500 web pages?
Huh, in that case I'm impressed with how Firefox has improved.
Yeah, I don't know what the "P" in "TP" stands for. Maybe "pageset". "T" is for "Talos". It's version 5. Or at least, the previous one was TP4 -- I don't know if there was a TP3. :)

Yes. TP5 is a list of 100 pages (based on Alexa 500, I believe, but I'm not sure), and we load the pages 5 times in 30 tabs.
