Fire well and truly Foxed

Well I've tried a few things to fix the display problems in Firefox - all in vain, I'm afraid. I searched Google for advice on 'Firefox display problems' - it returned 42 million pages !!! It seems that there are so many potential problems with Firefox that one could easily spend one's limited remaining life buggering about with this - I am not going to do that. If anyone has any bright ideas please let me know. Otherwise, Firefox users - you are foxed.
