Mostly I find Firefox 3, beta 5 a great pleasure to use. Fast and very intuitive user friendly way of working. Established Firefox applications are gradually becoming functional. Today I found Tab Scope works of FF 3 beta 5. This app allows the user to see a small preview of a page by holding mouse cursor over tab.
I cannot download exe files. Yesterday I could not do it on FF, switched to Safari then had to resort to Internet Explorer. Wish I thought of trying Opera first, but I was a bit tired of messing around. FF3 beta 5 is a beta, users are warned that it is only for testing, so I should not complain, and it's possible that the problem is restricted to my computer, or XP home edition (SP 2). I'll be switching to Mac X Leopard next month, but XP it is for now, which is the most widespread OS in the world at present.
