Hey all In the last couple of weeks I have been running Firefox and IE alongside one another. I am very pleased with Firefox, and downloaded Thunderbird too, which seems cool. Now I want to use Firefox as my default browser, and T/Bird instead of OE, since it seems you cannot uninstall IE, much as I would love to! The problem is this: I have unchecked "ensure IE used as default" in Internet Options; when I go to Add/Remove >Set defaults and change my options there, I either get a box which says it is transferring defaults to T/Bird and Firefox, which never completes the transfer, or I set defaults to T/Bird & Firefox, only for them to revert again. I must be doing or not doing something very basic here, but I wonder if anyone can help? OS is W2K Pro.
