Because of firefox 0.9.1 I have now switched over to Firefox full time and looking at bookmarklets (very handy) and have 2 for increasing the colums and widths of textareas on all pages witch I found great (index, forum edit pages)

Create 2 new bookmarks and copy the code in to each bookmark
Code:

Textarea Width Increase javascript:(function(){var i,x; for(i=0;x=document.getElementsByTagName('textarea')[i];++i) x.rows += 5; })() Textarea Height Increase javascript:(function(){var i,x; for(i=0;x=document.getElementsByTagName('textarea')[i];++i) x.cols += 5; })()

Each time you click on ether bookmark will keep increasing the width or height by 5

I annoyance is that it won't work on Textareas that have its style width and or height set

Looking at the code it may work with IE too but when I can't be bothered to run IE, 1 of these days I will check it out
