I saw that and was confused about it, as well. To a layman, one of the things I struggled with is the lack of documentation on this project.
I might be tempted to put a sort of documentation together, once I really got Netsurf running on my towered Amiga4000 PPC.
Not to say that Chris isn't doing great work, the browser definitely works on classic systems, but obviously it's not without issues. It's a big project for just one guy.
Chris does a humdinger of a job!
Anyhow, if you're trying to run this on a classic system you need to download the version from this thread,
O.K. - just did that.
But it seems I'm going round in circles, as the ReadMe of this archive says again:
"
Short: Fast CSS capable web browser
Uploader: chris@unsatisfactorysoftware.co.uk (Chris Young)
Author: NetSurf contributors (OS4 port by Chris Young)
Type: comm/www
Version: 3.4
Architecture: ppc-amigaos >= 4.0.0
This is NetSurf 3.4 for AmigaOS 4.
For the latest version, visit http://www.netsurf-browser.org
..."
I want the version for OS 3.9 - not the OS 4.x version!
AISS is not required (at least I didn't need to install it,
Hmmm - if AISS is not required - why did Chris write:
Prerequisites: AISS and a PNG DataType.
In his posting #572 Chris even wrote:
Oops, I should have mentioned that. It needs AISS installed, even if the default theme is selected (not sure why, need to check that). http://www.masonicons.de
Well, I have all the WarpDatatypes installed - including a PNG datatype, but I'm not sure about which AISS version to use (see my first posting #625).
Is the linked AISS version (aiss419.lha) for OS 3.x or is it for OS 4.x?
Unfortunately I cannot check its "ReadMe" here from work, as all I get is:
"

I'm running OS3.9 + BB1-4 + WarpDT's).
I'm running OS 3.9+BBs1-2/WarpOS 16.1. My TCP/IP stack is MiamiDX.
My hardware is:
A4000 with CyberstormPPC (50/200 mHz, 128 mB); MediatorPCI with Voodoo4, Terratec 512i digital and 10/100 mBit NIC in Zorro III; Deneb USB 2.0 highspeed in Zorro III.
Just unpack the archive, run the installer, it installs to a directory, assign NetSurf: to point that directory, and run it from the icon.
I certainly will, once I know where to get the latest OS 3.x version (the version linked for download here in this thread seems to be for OS 4.x, at least according to the ReadMe) and once the AISS issue is resolved...
You'll probably want to play around with the config options, there's a a few tips on those buried somewhere in this thread, haha.
LoL
But first let me get the stuff properly installed...

Good luck, post a screenshot when you get it running! 
Will do, but I'm afraid I will need more help to get it running...
