Firefox page display out.

[gort]

A number of pages viewed through Firefox (all versions) for some reason don't display properly. The formatting is all over the place.

Just started doing it one day, didn't change any settings (as far as I'm aware!)

Have updated, uninstalled/reinstalled FF, Flash etc without success.

An example is Youtube main screen below.

IE works fine but I prefer Firefox. I've Googled it and there are others out there with similar issues but I've tried what's been suggested without success. It's probably a simple fix and I'm being a numpty but any ideas?

EDIT: Just realised that on the google home page, the word "Google" doesn't display either; just the search box and below show.

Uninstall FF AND manually delete both your profile folder and the program files/mozilla folder.

Reboot then install away.

Looks like the stylesheet is missing. Have you tried clearing your cache / doing a CTRL+F5 on pages which don't work?

Thanks both of you, think it's sorted now. I tried CTRL+F5 and it appears to have done the job. If it goes again, I'll try uninstalling / deleting profiles etc.

Thanks again!
