I noticed the first thing I log on Firefox after turning on the Computer the top menu grey out (lock out sort of) so I'm unable to scroll the browser down or up unless I hit the left mouse button, its isn't a big deal. To get what I'm talking about when you're on Firefox browser move your mouse cursor down to the taskbar, click the taskbar with left mouse button.. See that? Noticed how top menu and the rest grey out (locked out) and you couldn't move the arrow key up or down (move the browser down or up as you're reading the news etc?) till you hit the mouse button to be able to move and the grey out is now white? The thing is this been going on like every once few hours whenever I pause for few second or about to scroll down it does that.. I noticed when its about to grey out (locked out) the icon in far right bottom kinda of flicking..you can barely see it and that when the top menu bar grey out (lock out).. I don't know if it was checking to see if add on need update, but it doesn't do that every few hours, I assumed only once a day it check for update on addon, I'm assuming the icon at far right lower are checking for update.. but I don't think that it. I can't say when it really start doing it, probably few month ago? I'm sure its not been a year, its more of like 2 or 4 month ago.. I don't think I got virus or spyware, since I got anti-virus sheild and other protection.. and use the other advance protection software to check for the files few time there none. Have anyone experiences this? Surely I can't be alone!?!? =0
