Re: Why you use K-Meleon?

I just want to thank you for this great browser. I needed a second computer and dug up this old Gateway 486-66 (with a massive 0.7 Gig hard drive) from my closet. I somehow managed to get an old NIC card to work, but could not get anything newer than Netscape 4.8 to run, and could hardly view any modern web pages. I could not even get the Microsoft site to load. K-Meleon loaded it just fine, and the web is actually usable. And I CANNOT manage without tabbed browsing.
I'll have to try this on my new HP Pavilion. If K-Meleon can run on a 486-66, it can run on ANYTHING.

That's the only browser that I can run on my old laptop Toshiba (486 DX2, 48 MB RAM, Windows 95) and surf the web.
Internet Explorer sucks nowadays, it displays a lot of scrap, popups and other s**t, older versions don't display most of the sites properly.
Kmeleon does it very well, tabbed browsing is what I like.
The only way to say whether one browser is better than another is to install both of them onto a slow machine. Then you can tell the difference.
Kmeleon is no.1 as far as speed is concerned if enough RAM is available.
I can give you a example:
K6-2-500 MHz with 640 MB of RAM, Windows 2000 pro SP4, DSL
http://weather.icm.edu.pl opening time:
1. Kmeleon - 17 secons
2. Firebird - 22 seconds
3. IE 5.5 - 23 seconds
4. IE 6.0 - 30 seconds
5. Mozilla 1.5alpha- 50 seconds
6. Mozilla 1.3 stable - 55 seconds.
On other, more complex sites, kmeleon is even faster.
