I'm using AGV and IE7... I had Firefox but I had to delete it due to lack of space on hard drive. XD Old computer, small hard drive...

answer,

Buy a USB thumb drive. Run Firefox off of said thumb drive

then you can do whatever you want on his computer and he can still use a perfectly fine setup that really has no disadvantages to the average user.

his right.
you can't change the mind of someone who uses logic in his thinking.
I would advice AVG over norton though

lolita, you might think about buying a new, cheap harddrive and moving all the large data files over to it...or just do a direct copy (ghost)
Whats your PC's Config?

Do like I did to my grandfather. I installed firefox and completely removed all instances of Internet Explorer for about 2 weeks while I was back home. Came back down and he was already used to it and could care less about IE.

Good information.

You're missing Most Correct View though.  It would be:  FF >> IE7 > Safari=Opera >>>>>>>> IE6. 

Most mediocre websites are coded specifically for FF/IE7.  Most good websites validate xhtml transitional at least making them capatible across the board.

Safari is decent on Windows, but if you're on Windows, you shouldn't be using Safari... there are better alternatives.

You ever hear the old saying, "You can lead a horse to water, but you can't make him drink?"  That's pretty much it.  If he doesn't want to use Firefox, you can't force him.  My parents use IE and Outlook too, and they also have Norton Internet Security and a popup blocker installed, and they wonder why their computer runs slower than molasses uphill and still gets infected when they click on ads.

One thing I will say is there's nothing forcing you to use IE on his computer.  Install Firefox, and leave IE as the default browser.  When you want to surf the web, use Firefox.  The great thing about a browser that isn't integrated into the operating system is that it doesn't affect anything else when you install it.  When I'm visiting with my parents and want to use the internet, I just run Firefox.  No big deal.

I was speaking from a design standpoint... any designer will ensure that their work displays correctly in IE but there are the occasional screwups, especially on large sites. But, hands-down, IE6 is the worst browser for correctly displaying code. IE7 is marginally better but has its own hangups. On nearly a daily basis, I want to kick the entire IE team in the nuts for refusing to conform to W3C standards. It's complete crap and it ends up costing me and my clients valuable time and money because MS wants to do things their own way.

Oh, and if you stick to standardized coding, Safari displays things correctly more often than Opera. Opera has its fair share of screw-ups while Safari is slightly better. Neither one is that great, though. FF is definitely the best.

Opera tends to have compliance as a badge, i.e. they have the minimum possible in each area to put it on their marketing, while Firefox tends to be compliant 100% in common areas and have little support for generally unused parts of the standard. Neither is perfect, of course, and full inline SVG in Firefox is desirable.

Iceweasel >>>>>>> Firefox>Opera>Safari>Konqueror>IE7>>>>IE6 is my opinion.
