I never use IE anymore. but what I do use depends on how I am feeling or where I am at when I need to download a new one. I have chrome on my M90 (sorry POS) and the desktop, and Opera on the D630 (cause chrome requires XP, and its not a software issue its a "you don't have XP or newer so we are gunna arse rape you and tell you we can't help you" issue. If there was a way to modify the system to read as XP I could get it no problem under it. but I digress. I have used Safari and firefox before, but I don't like the interface at all. :/ Really, I only truely support Safari as it is the only one that out of the box will still work in 2000. But Firefox might, don't know. I had it at one point.
