I'm using his Firefox ESR builds.  They suit me fine.  For now, that is

I tested the new Chromium on Win XP. It runs faster than Supermium. But there are a few things to note.

The RAM consumption bug when C++ is installed can be resolved by adding the corrected_api_sets.zip folder from Supermium. In XP x64, there is enormous virtual memory consumption, and I haven't found a solution.

WebGL is completely disabled, even the software version, which means that websites that require it do not work.

Manifest v2 is available but disabled by default. You need to add the parameter --disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled to the shortcut.

To disable the notification that the OS is not supported, add --test-type to the shortcut.

The browser requires a CPU with SSE3.

Browser crash during import fixed in version 144.

Please, as I don't have a GitHub account, can you ask to the developper to remove the code that delete all extensions when you move the portable versions of Chromium and Ungoogled Chromium from one computer to another. 

It's a horrible feature added by Google... 

I'm not sure about that but it seems that even some settings are restored by default with the move.

Tested with Chromium 146.0.7656.0 and Ungoogled Chromium 144.0.7559.59.

Are you sure that your profile is set up to be portable?  ie, with either a "loader" or something like "chrome++"?

[ED_Sln]

@genieautravail

The ungoogled version has the flags #disable-encryption and #disable-machine-id. Enabling them will disable encryption and machine ID creation, allowing you to transfer your profile to another computer. The developer will not transfer them to the regular version, leaving the functionality completely stock. Therefore, for the regular version, use third-party tools to create a portable version.

Yes, I use the loader of 360 Chrome browser.

Works very well with Supermium and Thorium too.

I will try these flags today.

Thank you for the tip.

Bugs identified on Windows XP SP3:

1. Sound stutters on YouTube and when switching tabs.

2. Crash when launching Shazam.

3. 1080p YouTube videos stutter.

4. A menu appears with a reminder about the lack of support for Windows XP and Windows Vista (not a bug, but annoying on these operating systems).

5. When switching from one tab to another while listening to the radio online, the speed of the sound slows down, as if it is being stretched.

@Slavich

Shazam has already been fixed. Stuttering and freezing of sound and video on YouTube is usually associated with a weak processor that lacks the power to process 1080 video, especially if it is VP9 and even more so AV1.

[NotHereToPlayGames]

Stuttering and freezing on YouTube is not a "bug".  It's expecting too much of an old processor, an old OS, and backported browsers to NOT stutter and freeze.

There are userscripts that can force h.264 and to force less-resource-hungry resolutions.  Again, expecting too much is not a "bug", it's a "reality check".

Another thing that I find helpful is to *INTENTIONALLY* "throttle" my internet speed.  It does not cause "lags", it forces the streaming service to NOT send me UN-NEEDED 4K.

I have updated my old guide about compiling Chromium. Now it only applies to compiling clear Chromium. A new one will be created for building with e3kskoy7wqk patches.

The developer's browser from the adjacent topic does not have such oddities.

The version there is significantly lower. Even between 2-3 versions, the load can be higher. Check the CPU load in Task Manager. If it is close to 100%, install the h264ify extension or https://vorapis.pages.dev/#/home/download

To disable the message about unsupported OS, do the following: 

reg add "HKLM\Software\Policies\Chromium" /v SuppressUnsupportedOSWarning /t REG_DWORD /d 1 /f

Just to confirm that the flags works with the latest Ungoogled Chromium (144.0.7559.133).
