A computer tech downloaded FF. Now all my .html files are FF files. I'm used to IE 6.0 where I can right-click, and view and edit source code. FF only lets me view. My IE also no longer has a menu bar. How do I get that back? I want IE to be my default browser.
Thx!!

Here's how to get IE 6 to be your default browser again.

1. Open Control Panel and double-click Internet Options.
2. Click the Programs tab.
3. Click to select the Internet Explorer should check to see whether it is the default browser check box.
4. Click OK.
5. Start Internet Explorer and when you are prompted to make it the default browser, click Yes.

Can't you just uninstall Firefox?
And also, for the menu bar, just rightclick at the top

Or, here`s a thought, why not let this so called "Computer Tech" fix his own screw up, especially if you did not OK the install of Firefox.
