.. oki well i'm learning howto grab what version of the browser as i'm kinda getting aware that some browsers need different code for things.

but i've come across a weird problem, or well just something weird.
why does it pass back this as my brower info?

navigator.appCodeName = Mozilla
navigator.appName = Microsoft Internet Explorer
navigator.appVersion = 4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
navigator.userAgent = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
navigator.platform = Win32

i mean i thought Mozilla was a different internet browser entirely
and this is my current browser version 6.0.2600.0000.xpclnt_qfe.021108-2107

so hmm... just wondering why these report things different to what i'd expect them to.

Mozilla is a seperate browser, but it lies to prevent websites from blocking access to its users (many websites won't allow the browser in if MSIE isn't in the useragent string)

using php you can write a clarification script by noticing mozillas always have a /then a number to indicate if its 4.7 or 6.0.

Yup. I'm using Opera but it's identified as IE 6.0. No detecting sites can tell.

I thought *most* browser's where actually based upon mozilla's code, or used large parts of mozilla's code for the browser?.

Im probably wrong lol.

Netscape does. Not any others that I can think of. Opera and IE are certainly their own code.

Bossy comment that most people hate: It's browsers not browser's

Yeah for a while Mozilla and AOL were together so Mozilla is just an open source Netscape...

Opera=(navigator.userAgent.indexOf("Opera") != -1) ? true : false;

and thats tha java of it
it just seemed weird to me that IE was comming back with the CodeName Mozilla and was returning v4.0 as the major one (when i would've though 4.3 would've been prefered) then in brackets a minor version.
just kinda confusing is all.

In Opera you can change the browser's identity. You can choose between Opera, various Mozilla Versions and IE 6.0. (File -> Quick Preferences)

indi, my brower dosen't broadcast as Opera, so your script can't tell. You can choose what to identify as.

And no, Mozilla is much more than an open-source netscape, it's faster and less clunky

Hmmm, okay .

You could make a page to check it, and we could see .

Personally, I think that if Opera can trick Microsoft's site into thinking I'm using IE 6, it's pretty undetectable.

Mouse -- AMEN! Mozilla, ah . . .

Looking forward to Mo's Firebird 1.0. Ah . . .

Opera is pretty good, though.

indi it returns the same info as the javascript version
people who change thier browers to fool should know there are ways around it no matter what.



Mozilla=(document.getElementById) ? true : false;
iExplorer=(navigator.appVersion.indexOf("MSIE") != -1) ? true : false;
NetScape6=(navigator.vendor == ("Netscape6") != -1) ? true : false;
NetScapeOther=(document.layers) ? true : false;
Opera=(navigator.userAgent.indexOf("Opera") != -1) ? true : false;

thats the javascript you'd need for each one... you just check particular elements, not matter what you set your broswer to they don't change.

heh, it works and it works very well regardless of client side issues.
In order to detect it tho you have to make it a priority before detecting mozilla and explorer browsers.
