Probably Mozilla Firefox, or possibly Seamonkey. Netscape 7.2 was actually based on Firefox 1.5 IIRC.
Anyway, it's up to you which way you want to go. Firefox is just a browser, no email, or anything else. For that you download something like Mozilla Thunderbird. Seamonkey is the continuation of the old Mozilla suite, and will have the email client and other stuff included.
They're both largely the same under the hood, it's just a matter of what's included with the download. Seamonkey does tend to lag behind Firefox in terms of development, but nothing too significant, and there will likely be at least a few extensions that will only work with Firefox. Still, I'd say give them both a try, see which one fits your personality better. They [either one] shouldn't have a problem importing data from Netscape 7.2, so you can try them both for a few days, and keep the one you like best.
I'm using "Windows XP" and still using Netscape 7.2. I'm beginning to realize the end is near.. Whats the closest Browser to Netscape 7.2 ??>
I love the E-Mail & Bookmark function.. I have "folders" set up to save things in, I just can't imagine having to switch to another Browser...
So if any of you know of another Netscape-like browser....PLEASE let me know.
