Firefox says im not indexed but internet explorer says i am??

I was indexed for a couple of weeks then all of a sudden i thought i wasnt indexed as firefox doesnt show any results when i do Site: I check in IE and it shows all the pages? What is going on? Have i been de indexed or havent i? I have already submitted a reconsideration to google and now i will feel stupid if it is just my firefox playing tricks on me, Has anyone had this problem before?

try clearing your cache/history/dns flush and see if it solve the problem

Cache of firefox is more likely the problem.

In January google made some improvement in their instant searches display to make it faster. I believe it is a source of new caching problems .

Cache is correct. Thanks for helping me out
