Thanks for the heads up. I'll look at the option tomorrow though I don't see a customise option for icons presently. Yes I think I used small or zero icons on v3 too. (Likewise I use folders for bookmarks on toolbar. All those related to particular topic or forum, etc.) But v4 definitely looks more crowded on the toolbar, something I don't like. With v3 I customised it to reduce that kind of thing.)

Last thing I want is to have to stretch the browser dimensions. Affects my work flow. ie: having multiple programs running simultaneously & in view at same time. Is a 30" apple monitor big enough or do I need larger because FF has made things more difficult?
