Research Network :: Porting modern versions of QT to Windows XP :: Reply by Darth Agnon

2026-10-11T14:04:11+00:00

I was doing some research for Qt 5 and 6 on Win XP, and found the following projects:

So I appear to have fucked up the QT on XP thing in the beginning and I need to like redo it and remake it and then I should have it working, I think. I might just avoid QT6 and recompile shit as QT5 since I have to rebuild it all anyways.

Pale Moon has been rather crashy in recent months. But they haven't given up and someone figured out and fixed the garbage collector, no more freezes due to it getting stuck.

Also wonder what to make of this.

Impressive !!!
That tells me that the Basilisk developer is working on something that is *NOT* UXP.
And, if I had to guess, does *NOT* target the XP Crowd.

No, people there are kinda weird and I'm apprehensive / reluctant when it comes to posting / asking certain things. The UI does look Australis, running on something that's not Windows (he's not a Windows guy). And the developer announced stop of development for undetermined amount of time.

So yeah, who knows.

I wanted to try his multi-process Basilisk, it mostly just prevents one tab from slowing the rest down, but apparently only works on Linux. I tried building it on Windows, but it crashes with some weird error about not being to load some resource and no one cared to look into it.

And not being into programming, didn't feel like digging into it.

I probably wouldn't be able to cope with C++ anyway. Even C#, which is somewhat humane, I get sick of and can't look at at some point.

Windows 9x and older :: How do you back up WinMe/9x? :: Author Darth Agnon

2026-10-10T18:30:00+00:00

I recently got down my mum's old WinME Dell Inspiron 8000 to polish, and decided I'd better back it up, in case the HDD flaked out. It has always been a flakey machine, and has stayed with us across 3 countries, me and my 2 brothers, my mum's degree, etc.

Most machines I just do a data backup with FreeFileSync and leave the OS and driver installers separate. But this old machine, I want to get everything with a disk image. Then I found out that DOS-based Windows doesn't have the Volume Shadow Copy Service and can't be imaged, without booting from a floppy disk into DOS. That's a royal pain and I have no floppies to sacrifice, nor do I trust this as a regular backup solution. I need to be able to image the computer/clone the HDD while it's On, in Windows.

Has anyone else had issues with this? What do you use to backup your old WinME/9x computers? Am I missing something obvious?

2026-10-10T20:10:12+00:00

On Windows 95 and 98, it is a trivial matter: Start -> Shut down... -> Restart in MS-DOS mode.
On Windows ME, you must install a patch to restore this ability. Such a patch can be installed from within Windows, without needing a DOS floppy, so do not worry about that.
If your machine has a CD-ROM drive, you can also trivially turn any MS-DOS floppy image into a bootable ISO ready to burn to a CD, if you would prefer that route.
Once you have such ability, you should use either PowerQuest Drive Image or Norton Ghost, the best version of which for 9x I am still looking into.
Update: This is apparently not the best way to go about it these days. I'm looking into other methods - I suggest you wait a minute.

Someone recommended me Acronis TrueImage, which allegedly has some sort of driver that functions in place of Volume Shadow Copy Services. I haven't tested that yet, though. I installed Norton Ghost, which was a bit unclear on if it could make a bootable CD (and I couldn't find a copy of MS DOS, as it comes with PC DOS).

I'd be very interested in that WinME patch to restore DOS booting abilities.

Eclipse r3dfox browser :: Suspicious r3dfox startup :: Author andrixnet

2026-10-09T05:53:35+00:00

r3dfox v128.14.1esr 32bit built for XP

r3dfox configured with homepage set to blank, network = no proxy, DNS over HTTPS turned off, otherwise stock condition (no additional extensions or themes, besides the stock ublock origin).

Upon startup, it attempts to connect to an IP from the 34.64.0.0/10 range (Google) using UDP port 443.
I block the connection, then it tries to connect to an IP from 172.64.0.0/13 range (Cloudflare) using UDP port 443.
Then goes back to Google and keeps trying from 142.250.0.0/15 range, same protocol and port.

What is this activity and why, given the above configuration?

To me it looks like DNS related, not honoring the DNS over HTTPS = off, because it starts again trying these connection with each new page I visit.

All Firefox (Official and Forks) do that.
It's background telemetry crap.

But it seems to no longer be developed.

I have the same issue as described in this report:
https://github.com/Eclipse-Community/r3dfox/issues/272

It's working fine with Firefox 115.42 ESR:

ZoomEarth-Firefox115ESR.png

But not with R3dfox 153.3:

Also notice that the commands box is broken with R3dfox.

The workarounds from the report don't work for me.

R3Dfox-ESR-140.11.0 on Win7 I found it to cause resource exhaution after some usage.
By that I mean "windows resources" - the ability of the OS to draw widgets.
This happens after using the browser for a while like 15-30min with 10+ tabs. or even less if using JS intensive pages like FB.
Closing the browser recovered the situation.

Interestingly enough, Firefox-ESR-115.40 update (recent) had a similar issue causing 100% RAM usage after a while and stopped loading new URLs then stopped responding.

See on multiple computers.

Today I updated to R3DFox-ESR-140.14.0 (portable, overwriting files except profile).
After over an hour of similar browsing things seem to be stable so far.

Thanks.

I wish there were more of you to speak like I do on the e3k and r3dFox Github pages. I get tomatoes thrown at me, but I STILL maintain that e3k had a great working version of Firefox ESR 140x that worked with Windows 7 and 8. But no ... he had to go cater to the XP crowd.

Better tomatoes than stones though! But yes, I don't get this XP madness.
That said, v140 ESR is EOL now. So is v128 which is not working anymore on some pages. The reason why I point out that Firefox releases cycle is faster than before now.

There's a lot of new development on XP at the moment - new drivers, new custom ISOs, new tooling for it, etc. So, XP is rather becoming more of a focus for a lot of the legacy development community.

It's actually kind of fun to watch. Strictly from the sidelines, as I ***wasted*** far too many years running XP.

We have several communities where their entire, and I really do mean their ***ENTIRE*** focus is XP but on brand-d@mn-new hardware.
Sub-forums for everything from Android to Linux to 10 and 11, but the XP on brand-d@mn-new hardware are the ONLY active threads.

It's kind of easy, and it really is as simple as this - Those that don't know their history are condemned to repeat it.

ie, Windows 98 went through this same d@mn "focus" for DECADES. Now the next generation is doing the same d@mn thing with XP.

There is potentially more reasoning to this, though. We have source code for XP now, and XP is built on the much more stable NT, rather than 9x. Yet, it predates Vista's complications of componentization, MUI, CBS, TrustedInstaller, WDDM, etc. Plus, far less effort is required to port to XP than was to port to 9x. It is quite a different matter, and there may be a lot to gain from it.

I'm not "yet" convinced.
I've been watching a lot of this going on in other forums.
One of them even provided an .iso and I installed that on hardware that is less than a year and a half old.
So far, I'm *not* impressed. Doesn't mean that I won't be at some point in time.
But keep in mind that I'm also not comparing these XP Mutant Ninja Builds on 1yr old hardware to "10 or 11" on the same 1yr old hardware.

I do things like DPC Latency checks and "debloats" and that type of stuff with my Win10 and my point is basically this -
It is FAR easier to debloat the crusty edges out of Win10 and obtain a truly efficient "screaming" machine...
Than it is to "hexify" XP and obtain the same level of "scream"...

Makes sense - if you're trying to just compare OSes, you'd need to be comparing them on the same hardware.

Performance is different for every different workload and hardware - and not everyone cares that much about performance anyway, as an interface that you prefer can be a major time saver too.

idk XP is like fun. I do like try to get it running on modern hardware for the fun of it. However like for older machines where I need to test random stuffs on, I may have like a multiboot of XP, 7, and maybe one or two other operating systems. If I need XP, it would be cool to have a good browser there too, which is also why I try to keep all the programs I use as close to XP compatibility as I can. For even older machines that's also why I do Lun3r and eMail and co.

EVERYBODY that I know cares a GREAT DEAL about performance.
Some even to the point of "throwing away" a perfectly AWESOME computer because it is "three years old".

My Ungoogled Chromium running on Win10 LTSC 21H2 has some tweaks, but it is "my" FRAME OF REFERENCE for anything browser-related.

I argue this differently than others.
Some (and they would have to provide their own proof) claim that e3k's browsers are "slower" today compared to 6 months ago BECAUSE of XP.
I have never tested this theory. Nor have I seen proof provided that basically says e3k is going downhill ever since including XP.
Again, I have not tested (and nor will I - personally, I would prefer that e3k abandoned XP ***AND*** 7 and focused on zero-AI and zero-telemetry forks).

As far as I can tell, e3k's browsers, both Chromium and Firefox, work ***BEST*** in Win7 !!!
Not by that much over Win10.

And additionallly, e3k's browsers, both Chromium and Firefox, work ***WORST*** in XP !!!

Now then, what does the HISTORY of e3k's Win7 performance say?
Does a version 6 months ago work even better than my Ungoogled v144 ???

BUT...
If a version 6 months ago is IDENTICAL, *relatively speaking* (different version simply due to Upstream will vary), than WHO CARES if the developer started to include XP support. Since NO EVIDENCE has been provided to demonstrate that it would be "faster" if the developer did NOT take the XP route.

I'm not saying it's not interesting nor exciting. But since the beginning R3dfox was made for Vista+.
As of today, R3dfox is already 2 versions behind Firefox. I'm sure there are more Windows 7-8-10-11 people using R3dfox than XP ones. Because yes, I know people who prefer to use R3dfox than Firefox on Windows 10 and 11.

So all these 7-11 people are let down because of very few XP users and an intellectual challenge ?

Yet I would have been REALLY happy to get updates to v140x ESR (and even use that until the end of the year). The 153 ESR version seems hard to configure with a title bar and tabs under the address bar like this.

Not true per se (I have Vista SP2 x86 here, so I know firsthand ) ; initially, the browser would only target Win7 SP1 x64 ; the first build that promised Vista SP2 support WITHOUT VistaExtendedKernel was Beta v126.0.2v:

https://github.com/Eclipse-Community/r3dfox-old/releases/tag/v126.0.2v

Then came:

https://github.com/Eclipse-Community/r3dfox-old/releases/tag/v115.13.0esr

https://github.com/Eclipse-Community/r3dfox-old/releases/tag/v115.13.0esr-stable

And the very first "release" channel build with native Vista (SP2) support (even for x86 - but without sandbox there) was:

https://github.com/Eclipse-Community/r3dfox-old/releases/tag/v128.0.2

Changes on top of the previous 128.0 build:

I don't feel like editing the post right now, so I'll leave a few notes.

Now each mozconfig compiles to it's own specific directory, so you can build all of them and not need to clobber any.

IA-32 is now as simple as just using the IA-32 mozconfig. No fiddling required.

eMail patch instead of being a different branch now is a patch that can be applied with git apply 0001-platform.patch

If you want to go back to compiling UXP after applying said patch, run git apply --reverse 0001-platform.patch and then git clean -d -x -f and you will be able to build UXP again.

I haven't found it in my archives. I guess because I don't have much stuff from XP x64 and Server 2003 as I've never used them.
But maybe it's included in this build published in 2024 ? :

Or here:

According to this page the problematic file is Classpnp.sys and the patched version is 5.2.3790.113:

Ah with your link I realize this update is ancient, before SP2. The newest SP2 classpnp.sys is far later than 5.2.3790.113, so this is just not applicable to it.

Was chasing a potential lead for an issue, and ig that closes this one.
