Strange problem with Update 11.3-U2

[OG_Flicky]

So this is a bit of a strange one i have installed the latest update 11.3-U2.
The problem is when i try to use any of the menu funcions while using Firefox i can not click on anything but when i use chrome it is working fine.
Is anyone else having this problem or do they know how to fix it?

up until now ive never had to post anything because ive never had a problem in the year ive been using FreeNAS

I saw the same issue -- but Ctrl+F5 (which clears your cache) will fix it as @Yorick said.
