Facility says I need Firefox 4, but I'm under Firefox 3.6.1 but when I go to properties it shows Firefox 4.00

I installed Firefox 4 on my laptop (upgraded) and when I need to install an extension, it is said that I need Firefox 4 to run and I'm in Firefox 3.6.10. (I already installed on my desktop without problem)

Followed the instructions above, but reboot is grayed out
