Facebook is left justified on my machine only. erashing cache does not fix it. need help.

Question

this just started today.
i've followed every single step on the support with no change.
-i've updated to firefox 10
-i've cleared both caches 10 times, also used third party programs and manually after that did not work. no change.
-i've tested the font size (it's where it should be)
-tested java script (it is on)
-tested zoom. When zooming in or out the page fixes itself and goes centered, but when at the default zoom, the site is left justified instead of centered.
i would really appreciate some help here. bad enough firefox crashes enough for other reasons, but now that the number one page i go to on a daily basis isn't working right it's basically enough reason to leave for good.

Answer 1

I have an answer!!!
Check it out, I uninstalled Firefox and IE from my machine, reloaded the default IE.
When I reloaded it (IE) and went to facebook, my machine said there was a certificate error, i hadnt seen this before for some reason (my wife ignored it or something).
I clicked ignore and it came up with the left justified angry mess we all hate so much, well IE then popped up in the bottom saying something about blocking the content associated with the bad security certificates, also giving me an option to display said content, i clicked the button and low and behold beautiful colorful facebook pops up.
Well I press back and go back to the Certificate Error screen and I click on technical details, it says something along the lines of "Certificate for this website works starting November 11, 2011, and system time is march 02, 2002.....
.......wait what?
I look down, sure enough, system time, 2:44AM, 03/02/2002.
......So I reset the time (this tells me, by the way, i need to crack open my laptop and replace that little nifty system battery that keeps the clock accurate, they go out every so often, newegg/ebay sells them for cheap),
so after i reset the time i simply (on the error page even) hit refresh and bam, like there was never anything ever wrong.
Conclusion: if your system time is messed up (how often do you really look at it) and the year is wrong, it'll screw up EVERY browser you try to use, because every browser (in an attempt to protect you from risky websites) is blocking content that doesnt have a valid security certificate (because the date is xx years away from even being initiated).
Hope this gets to you in time before you go all Office Space on your computer.
