QTWebKit Browsers QupZilla - Dooble - QTWeb Internet Browser


Recommended Posts

We mostly talked about QupZilla version 1.1.5 in the past. I have now tested newer versions again. Yes, it does not meet fast development and is basically obsolete. It can be interesting for the KernelEx 4.5.2 user to have an alternative for Firefox 9.0.1 or 10.x with RT's Network Security Services nss update.
Qupzilla 1.3.5 runs with Javascript disabled. In my opinion, today 1.8.9 (last XP version, but 2.0.2 runs on my XPSP3, too) isn't much better in terms of website display either.
Its OpenSSL (LIBEAY32.DLL, SSLEAY32.DLL) is nearly unusable, but I can simply update that version by replacing these files. Newer versions support important cryptographic protocol TLS 1.2, too.
I tested that on two machines. On the first with KernelEx core updates 25 (Kext disabled), I use OpenSSL (1.0.2u), on the second with KernelEx 4.5.2, I can use version (1.0.2L) or alternatively - I think it was -, in any case, however,


e.g. https://www.dll-files.com , https://www.npcglib.org/~stathis/blog/precompiled-openssl/ , https://indy.fulgan.com/SSL/Archive/

History and Bookmarks work. The tests are with the portable version (portableapps.com launcher).

Disable Javascript in the settings.ini.

[Web-Browser-Settings] allowJavaScript=false
Path Portable: ...\QupZillaPortable\Data\PROFILE

Unfortunately, I did not find some old versions like 1.1.8 or 1.2 anymore, even on archive.org for the possibility to try an older dll of Qupzilla to enable JS.  Presumably Javascript of those old browsers brings quite little.




KernelEx mode: Win2000SP4

The portable 1.3.5 already have Launcher 2.2.0, that doesn't work on ME/98. The Launcher can be replaced by the next older Launcher 2.1.2.
Because I couldn't find any older versions, I built it myself with the PortableAppsLauncherGenerator 2.1.2 and NSISPortable 2.46.1.

The successor of Qupzilla is Falkon browser.
I assembled a first API list:


I started experimenting with DX10/11 , mesa, wine files, like dwrite.dll, libwine.dll, wined3d.dll. Apparently there are mandatory dependencies for Falkon here.
For testing I have to enable among others [D3D9.DLL]Direct3DCreate9Ex, [msvcrt.dll]memmove_s=>ucrtbase.dll:, [KERNEL32.DLL]InitOnceBeginInitialize=o4e, CompareStringEx=z9e.
I can't leave them on permanently because various errors result in other programs. I enable them for testing only.
Is there a Falkon browser setting to prevent these calls similar to Firefox "layers.acceleration.enabled;false", "webgl.angle.try-d3d11;false"?

Dooble Browser


Dooble.exe files can be unpacked with 7Zip, too.

1.30 runs on ME/98. Extremely unstable with JS enabled. Javascript can be disabled in the Dooble.ini ([settingsWindow] javascriptEnabled=false). The profile name is ".dooble" and is in the program folder (...\DoobleBrowser\.dooble\Dooble\Dooble.ini).

1.43 (2013): Start it once. After the crash disable JS (see above). And try to start Dooble again. If this doesn't work, run it on XP and disable Javascript. Afterwards use the new profile on ME. On XP the profile name is OS user name (...\DoobleBrowser\-username-\.dooble). 1.43 crashes immediately with JS enabled.
Updated: libeay32.dll, ssleay32.dll, libssl32.dll
I can't find some Dooble versions anymore, also not on archive.org.

KernelEx mode: Win2000SP4

QTWeb Internet Browser
Development has been discontinued. But the Website is still online. Latest version  3.8.5 (2013). It already supports TLS 1.2.
3.8.5 runs on ME/98. Javascript must be disabled. Before you allow internet access you must disable JS, otherwise QT Web will crash. Or set JS in the registry to disabled: (HKEY_CURRENT_USER\Software\QtWeb.NET\QtWeb Internet Browser\websettings) String enableJavascript to false.

Portable version: Profile folder > ...\QTWebBrowser\QtWebSettings\QtWeb.NET > QtWeb Internet Browser.ini [websettings] enableJavascript=false

KernelEx mode: Win2000SP4

Slimboat - latest version 1.1.54 (2015) It crashes on start.

After a web search I have versions 1.1.17 and higher. I also found an older version 1.1.8 (2012) on my HDD.
QtWebKit4.dll 4.9.3 can be replaced by an older version (e.g. of SB 1.1.8) to start without error. Don't take QtWebKit4.dll of 1.1.17 or newer.

Configuration version 1.1.52 (2014), with older QtWebKit4.dll (4.7.4), libeay32.dll, ssleay32.dll

Problem - versions 1.1.53 and 1.1.54: Disabled SSL 3.0 protocol disables TLS 1.2, too! This is probably unwanted and a bug.

Changelog 1.1.53: "Added option to disable SSL 3.0 protocol to avoid POODLE attack. SSL 3.0 protocol is disabled by default. If you wish to connect to legacy websites supporting only SSL 3.0, you can turn it on in Tools:options:security."

Configuration: QtWebKit4.dll (4.7.4), libeay32.dll, ssleay32.dll

Javascript doesn't matter.

Portable: The setup exe can be unpacked with 7Zip (no installation). Delete $PLUGINSDIR and $TEMP. Then create a file settings.ini in the SB program folder with entry


The profile folder appdata appears on SB start.

https://www.afterdawn.com/software/network/browsers/slimboat.cfm/v1_1_17#all_versions The versions below (1.1.17 - 1.1.54) have the wrong name.. Slimjet = Slimboat




KernelEx mode: Win2000SP4

Versions 1.1.33 and higher require Kext or KernelEx core updates. KernelEx 4.5.2 users can try version 1.1.32.


Not usable:

Midori Browser doesn't quite fit in here.

Version 0.46 (2012) works, but is nearly unusable. Apparently no https, no TLS 1.2 support. 0.47 comes with a new libjavascriptcoregtk-3.0-0.dll and Midori causes an error in that dll on start. Disabling JS doesn't help in this case. KernelEx mode: Win2000SP4

Anyhow Midori versions are available on archive.org.



Xombrero keyboard controlled browser (discontinued) - latest version 1.6.3 (2013) on sourceforge


missing APIs (Hresult)

It starts with error in libjavascriptcoregtk-3.0-0.dll like Midori!

On XP Xombrero runs by replacing USP10.dll by the file of vista. But in my opinion it isn't really usable anymore.
