How set this using add reg in batch script ?

Yea, on my laptop ThinkPad X220 also no AGP Texture... available on Intel GPU 3000 - driver 5437:

@Dietmar Oh OK. I didn't know Intel's 14.x XP driver did that. No worries with 5449 then, it'd good enough that you made the 5445 mod.

@Damnation AGP Texture Acceleration = Not Available is normal with Intel 14.x XP drivers, so also for the 5445. Intel reports the graphics memory as local video memory, so DXDiag does not expose the old AGP/non-local texture path. For to modd the 5449 I have no mood Dietmar

I haven't gotten any such message. Lately the site often refuses to load showing nothing (likely due to some content being blocked), and I need to refresh a few times. The Ad-Shield domains keep changing. When ads are loaded, they rotate often with constant network activity. They want to "gamify" e-mail now with some "achievement" earned from using e-mail several days in a row. No doubt to look at the ads. The biggest Ad-Shield client I found is Wikia/Fandom. The site is already heavy without ads. And when it redirects to error-report, it must be loaded fresh in all its weight.

These are the elements that Palemoon has issues when I visit Github that max the CPU and stays high until I work out which one to Zap*. Will be nice when Palemoon becomes upto date with github code for no more high CPU there. https://github.com/gorhill/uBlock/releases Rotating Circle <circle cx="8" cy="8" r="7" stroke="currentColor" stroke-opacity="0.25" stroke-width="2" vector-effect="non-scaling-stroke" fill="none"></circle> <path d="M15 8a7.002 7.002 0 00-7-7" stroke="currentColor" stroke-width="2" stroke-linecap="round" vector-effect="non-scaling-stroke"></path> https://github.com/gorhill/uBlock/issues Open Closed Buttons (polyfill shadows) <div class="LoadingSkeleton-module__skeleton__euqGn LoadingSkeleton-module__pill__Dlvex SectionFilterLink-module__counterLabelSkeleton__DhRz4" style="width:32px;height:18px"></div> <div class="LoadingSkeleton-module__skeleton__euqGn LoadingSkeleton-module__pill__Dlvex SectionFilterLink-module__counterLabelSkeleton__DhRz4" style="width:32px;height:18px"></div> Below I tested the violentmonkey project for interested to see if same and what if any changes made with Palemoon viewing Github On loading max high cpu I used the zap Anything Add-on the assets circle - this is what the Palemoon developer showed for the element code (below). Afterwards the cpu dropped low and after went high max and remained continuous at cpu max. At times like these we need the Super Stop Add-on for Palemoon with a button the reacts fast when selected. https://github.com/violentmonkey/violentmonkey/releases/tag/v2.47.1 <span data-view-componment="true"> <svg style="box-sizing: content-box; color: var(--color-icon-primary); outline-width: medium; outline-style: none; outline-color: currentcolor;" width="32" height="32" viewBox="0 0 16 16" fill="none" aria-hidden="true" data-view-component="true" class="anim-rotate"> </svg> . * Zap Anything v1.4.2 (falna) add-on basic but does items and can help the cpu to stay lower removing those items (not ideal but what other have we got) At Github projects such as youtube-dl and other ones.

Well, it was a matter of the purest optimism to have posed the query in the first place.... Perhaps @roytam1 could implement the pref and use it to temporarily shut off :has() support, in the hope that an upstream fix will soon be available.

No...

Does UXP's new :has() support honor that same about:config pref? If so, disabling the pref might be a workaround for the serious performance issues with it.

.css files are all over the place at github. Instead of one very large .css, they seem to use dozens upon dozens of smaller .css files. I only opened three of them and all three used the :has() declaration. While I am not proclaiming the newly-implemented :has() is the root of all of these issues. BUT... it is the ONLY change implemented in the most recent weekly update. So one really doesn't need to have to dig too deep into the change log to see just "what" is causing recent issues.

... But the :has() CSS pseudo selector has been enabled by default since Fx-121 (release channel), while earlier implementations were behind a disabled about:config pref since Fx-103: https://caniuse.com/css-has Firefox is now at version 153.0.4; surely, one can't really blame website owners if the web frameworks they employ make use of :has() ? Even FxESR-115 (supported until March 2027) used on Win7/8/8.1 has the support easily accessible behind the "layout.css.has-selector.enabled" flag; as we've discussed multiple times in the past in these threads, the UXP platform remains oblivious to (practically) all of modern web designers, as backwards-compatibility isn't "a thing" anymore since many years already ; Mozilla use Stylo (or whatever it's called now) for Firefox's CSS features and this is unavailable to UXP devs, so I kind of feel for them ; hopefully, their first attempt at supporting :has() can be made a lot better (if indeed that's the major problem plaguing now GitHub pages, which I'm mostly concerned about ) ...

I realize I'm just an old fart now, but I still don't think it's crazy for me to stick to my ancient 2023 ways, and watch only one video at a time. That said, I suppose it's reasonable for someone to want to "keep an eye on" a live (not prerecorded) video or two other than the one they're actually watching. An example might be watching the local sports team play, while keeping an eye on rival teams' games. At least as long as you can back up and replay the last several seconds if something interesting happens. I even suppose it's possible that some folks are trying to do that sort of thing with their Web browser on an older OS like Windows XP. However, I suspect that's quite rare nowadays.

It's because that page uses a ton of ":has()" .css declarations. This is the very first roytam release that even knows what ":has()" even is. Just one example from loading that page == https://www.comparethemarket.com/assets/Layout.wkRwGAqn.css Note that there are NINE :has() declarations in that one .css file. That page also pulls from a CDN == https://cdn2.comparethemarket.com/experience/web/assets/webui/2.0.0/css/everything.css There are ONE HUNDRED THIRTY FIVE :has() declarations in that one .css file. I can screencap these if you want me to.

Is this the same thing? With Serpent v52.9.0 (2026-08-13) (32-bit) go to https://www.comparethemarket.com – no need to even allow javascript – and simply circle the cursor over the page. Page doesn't even need focus. The CPU goes nuts. Going back to Serpent v52.9.0 (2026-07-31) (32-bit) fixes the problem. Ben.

The basic and in my opinion enough is to disable the automatic defragmentation and of course not to do it manually. Trim is supposed to be unnecessary for the modern SSDs.

I can actually browse GitHub in New Moon 32-bit (latest), but during page load CPU goes to 100% for a while and when that has settled down, clicking on something makes it go to 100% again... Scrolling reacts very slow. (XP SP3 VM; 3.5GB RAM; 1 core assigned)

so the problem may be in :has css support code: https://repo.palemoon.org/MoonchildProductions/UXP/issues/3165

@Dietmar Success for me too! https://ibb.co/yF15pPPr Thanks very much! Can you apply the same fixes you did to the 5449 driver too? (5449 is the last intel graphics driver released for XP as far as I know) https://buzzheavier.com/9ktobfemwe7o edit: Also, can you figure out why AGP texture acceleration is not available in direct X? I think it should be available?

As always, my single-core 32-bit P4 is the perfect tool for diagnosing errors, performance issues and so on. In New Moon 28 32-bit 20260815, any GitHub page causes the entire browser to freeze when it is the active tab. You can’t click on anything anywhere in the interface. A total fiasco.

FFmpeg update. XP: static shared libfdk-aac VISTAx86: static shared libfdk-aac

I think it will be enough to disable the Prefetcher, system file defragmentation at startup, and hibernation. And run Trim periodically — O&O Defrag can do that.

Doesn't Yahoo Mail basic/free have a no-ad-blocker-allowed policy now? I remember getting some message a while back, probably like this
