Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).

"Clear the Cache":

"Remove Cookies" from sites causing problems:

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

• Don't make any changes on the Safe mode start window.

i've tried the cache removal multiple times. just tried remove cookies, and safe mode as well. absolutely no change.

the strangest thing is that if i zoom using CTRL and the mouse wheel, either one level up or down, it will center, but at the default zoom it does this. I've tested on 6 other machines and can not reproduce the issue.

additionally, i had installed nothing new, or done any changes to my computer before this happened. I had firefox open and it was fine, next time it was open after playing a game for a while, it was like this.

and here is a picture. black boxes/blur is just my censoring. http://img72.imageshack.us/img72/2697/92835422.jpg

If you have increased the minimum font size then try the default setting "none" as a (too) high value can cause issues.

• Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow websites to choose their fonts.

• Tools > Options > Content : Fonts & Colors > Advanced > [X] "Allow pages to choose their own fonts, instead of my selections above"

• https://support.mozilla.org/kb/Changing+fonts+and+colors

It is better not to increase the minimum font size, but use an extension to set the default page zoom to prevent issues with overlapping text or text getting positioned wrongly.

both of those are already set that way. changed them and reset and same result. no change.

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

• https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

See:

• http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

just tried that. no change. additionally i removed firefox from my computer, removed every single file and folder from the computer, and even wiped the registry of firefox, and its STILL happening.

okay, now i'm at a total loss. right after i posted that, it's now happening on chrome and IE....

Do you have security software (firewall) that can block such CSS files?

You can try to reset (power off/on) the router to see if that helps.

• http://kb.mozillazine.org/Websites_look_wrong

disabled my entire antivirus and firewall, no change.

restarted the router and tried 3 times. no change

then tried everything else on those two pages i didn't try yet. no change.

still same thing on firefox, chrome and ie. but it still started on firefox. wasn't until i tried erasing/reinstalling firefox that it popped up on the other two.

so i guess thats it? theres no way to fix this short of reinstalling windows at this point?

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. (I created an account JUST to write this reply)

In hindsight I realize it worked for everything but the default mode in your situation. I looked at your screen shot and your system time looks fine.

So nevermind. I feel sheepish. In case anybody else ever has this problem, perhaps my answer will help ^_^

I found this thread in search of my own answer to my own question.
