THIS IT WHAT MY MOZILLA WINDOW LOOK LIKE

THIS IT WHAT MY MOZILLA WINDOWS LOOK LIKE. PLZ HELP!

I have the same thing... :/ What is it?

Try disabling that Persona, and revert to the Default theme (Tools > Add-ons > Themes). See Use themes to change the look of Firefox and http://kb.mozillazine.org/Themes (Lightweight theme)

If that doesn't fix the window size, do you have that problem when running in the Firefox SafeMode? http://support.mozilla.com/en-US/kb/Safe+Mode Don't select anything right now, just use "Continue in SafeMode."

If not, see this: http://support.mozilla.com/en-US/kb/troubleshooting+extensions+and+theme...

Same problem in Germany, is it a virus, a trojan or some kind of malware???

I found one add-on which cause the problem - "FBFAN" - I don't know what was that, and how it get into my firefox, but uninstalling solved the problem.

THANK YOU GUYS FOR ALL YOUR HELP... IT OKEY NOW. I JUST REMOVED ONE ADD-ONS THAT I DONT REMEMBER ON INSTALLING. MOZILLA SHOULD CHECK ON THAT. I THINK THE ADD-ON THAT I UNISTALL WAS SAME AS MARKUS...

THANKS AGAIN! :)

It would be really helpful for us "helpers" if you tell us exactly which addon or extension was causing that problem for you (like Markus did), to help us help other users who may have that same problem.

thankx guys just googled the "FBfan" - it's a facebook become a fan add-on. suggestion also helped in my case, thx a lot
