most of the time nothing has even changed on these tabs but yet i kept them open because i was looking at a whole bunch of things at once then firefox crashes and i get annoyed.

Reproducible: Always

Steps to Reproduce:
1. open lots of tabs
2. set firefox to load previous tabs from last open session 
3. close then open firefox and watch as they all reload causing a minor to major slow down
Actual Results:  
SLOW

Expected Results:  
depends on how fast your computer is too fast for you to notice the lag

not reload upon opening of firefox
