It seems like the folks over at Pale Moon already removed Rust from Firefox 52 and 55 (in the form of UXP and Móbius). It should be easy to do it in FF60 or 68

60 already has Servo code, so I'd expect that to be somewhat hard.

General Software & Hardware :: Safely disable secure boot :: Author Duke

How to safely disable secure boot on a ~12 years old computer ?
There is no ON/OFF switch. I can either switch from UEFI to Legacy OS or delete the secure boot keys.

What is the best to do without losing data or destroying the boot ?
And please, I don't want AI answer but personal experience.

Clearing the secure boot keys will leave you in UEFI mode, with secure boot technically enabled but not active (anything will be accepted to boot, even if unsigned). Disabling UEFI will obviously leave you not in UEFI mode.

So you suggest to stay in UEFI mode and to delete the secure boot keys ?
Are you sure it will be able to boot without altering the OS ?

Knowing that one PC is running Windows 8.1 and the other one Windows 10.

Indeed. If it currently boots, it will certainly boot just fine after deleting the keys. You would only need to enable legacy mode if you plan to install Windows Vista or older on it.

Browsers :: Pixel Unmute :: Author The-10-Pen

There's an extension called "Twitch PixelMute" (originally a Firefox .xpi but can be unzipped and manually installed in Chrome).
Found here: https://addons.mozilla.org/en-US/firefox/addon/twitch-pixelmute/

What it does:
By way of an "eyedropper", you create a rule for an exact pixel location and color for it to monitor.
Think of an ad that says "skip ad" in the corner, define your rule by selecting a pixel in that "skip ad" button.
The extension MUTES the browser when that pixel "rule" is detected.

Problem:
It only works on Twitch (never heard of it), Kick (never heard of it), and YouTube (useless because uBO already blocks ads).

Concept:
This should be done in REVERSE.
ie, don't MUTE a tab based on a pixel location and color but rather MUTE BY DEFAULT and *UNMUTE* based on pixel location and color.
I'm thinking of the way that pretty much all television streaming channels operate - the channel's LOGO in the corner AT ALL TIMES.
But there is *NO* logo when the streaming channel is playing an AD.

I'm not using Twich much but last time I did, about 2 weeks ago, I didn't had any ads.
Using uBlock Origin + uMatrix + NoScript. I know, some may say it's too much and redundant in some cases, but at least I have full control over the content.

Not sure why you moved this to the "Browsers" section.
Perhaps "Concepts" wasn't the right location, but why "Browsers"?

I actually have a "working prototype" (very buggy, but 'proof-of-concept') using AutoHotkey.
System-wide, has nothing to do with "browsers".

Because it's a browser extension and the Browsers forum belongs to Hardware, Software and Customization → General Software & Hardware → Browsers.
The Concept forum is about "Have a concept you made and want to share? This is the place."

Gray area.
I'm using AutoHotkey (has nothing to do with any web browser and is not an "extension") for a working system-wide prototype.
But yeah, all of my streaming is via web browser (but it doesn't have to be).

I believe this commit is a bad idea: Don't unnecessarily upsample audio to 32 bit
https://github.com/Eclipse-Community/r3dfox/commit/8e6a2f27506d2dd589b25ba00591b6fb4d76c0ee

PCM means integer being used while Float means floating-point. The purpose of using 32-bit floating-point is to avoid clipping:
https://en.wikipedia.org/wiki/Clipping_(audio)

Because of a better amplitude, to sum it up:
https://en.wikipedia.org/wiki/Audio_bit_depth#Floating_point

For instance, 32-bit floating-point is the default mode used by Audacity when working on a sound track because you don't have to worry about levels until you save the file at the end when you then reduce the sampling rate, the bit depth, apply dither and use an integer format such as MP3.

Audacity-32float.png

So I believe 32-bit floating-point output is used for a good reason and for best compatibility and shoudn't be changed.

I've found that going over 16 bit for lossy formats results in quality loss, to the point where taking a bit of clipping is better imo. What got me to make this change was when I noticed a meme sounding weird in r3dfox compared to Electron (Chromium). So I went and traced this, and undid the change.

I also did the same for an attempted fork of Audacity, but it kinda died since I expanded the scope of it a bit much, and 2.3.3 does basically everything I need it to anyways.
https://github.com/the-r3dacted/audacity/commits/testbase/

Although I could probably experiment with it and put it behind a pref, but I've already built 150.0.3 so maybe later.

Technically speaking, this is not possible. The extra pad from 16 bits to 32 bits is just filled with zeroes so it can't affect the sound quality in any way.
It's just about the decoded output. Upsampling can't create sounds that don't exist in the first place.

About this issue report:

Windy.com works for me but it requires to allow WebGL.

But the user agent workaround for https://marinesafety.sa.gov.au/web-cameras doesn't work for me.
Whatever I'm doing with R3dfox I always get "high_res?codec=hevc"

It works with Firefox v115.36 ESR only if I open the frame in a new tab or window.
Then I get "low_res?codec=h264".

Looks like the site has a way to detect the real engine of the browser and/or the real OS.

I have noticed that too and I wonder why it doesn't work anymore
It was working fine in previous versions and hardware decoding should work at least for H.264 which is really a long time standard.

1: Have an install of Windows 7 or later. Vista might work, but I have not tested it.

1.5: Install basic prerequisites. .NET 3.5, .NET 4.x, VC++, etc. If you're using one of our ISOs, you should already have these. If you're using 8.1 Lite from here, you will need to grab C:\Windows\SysWOW64\upx.dll from a regular ISO and add it to your install. If you're on Windows 8+ and having trouble installing .NET 3.5, mount your install media, open an admin cmd, and run this. `DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs` (Replacing D: with the drive your install media is in. For some debloated 10+ ISOs, you may need to do this with a stock ISO of the same major version.)

2: Grab the main prerequisites for building, MozillaBuild 3.2 and FWDK-15 (Specifically FWDK-15.7z and Min-DX-SDK.7z), and Git.

Newer versions now require NASM. I'm a bit skeptical of using the latest versions of dependencies due to potential unintended issues coming from having too new of a dependency. The minimum as of writing is 2.14, and so I use the latest 2.x version 2.16.03.
https://www.nasm.us/pub/nasm/releasebuilds/2.16.03/

3: Install the prerequisites:
MozillaBuild, you can just run and install MozillaBuildSetup-3.2.exe. The only thing I changed is I added -3.2 to the end of the install path, so it installed to C:\mozilla-build-3.2 and that's all.

For FWDK, extract FWDK-15.7z and move the extracted FWDK-15 folder to the root of the C: drive. It should look like C:\FWDK-15\(MSVC15 and Windows Kits)

Other dependencies I like to keep under C:\DEV\ so it doesn't crowd the drive root directory up too much. This includes Min-DX-SDK.7z, extract it inside C:\DEV\. It should look like C:\DEV\Min-DX-SDK\(Include, Lib, and Redist) For NASM, you'll need nasm.exe from the downloaded zip file. you can make a C:\DEV\PATH directory, move it there and add that to the PATH. Or you could just stick it under C:\mozilla-build-3.2\bin. Either will work here.

Install Git, either as GitHub Desktop or regular Git. For detailed instructions on how to do that, refer to the r3dfox build guide.

4: Clone the source code:

By default Git/GitHub Desktop will clone with Windows style line endings since well we're on Windows, however this causes issues with the Mozilla build system. Open the command prompt, and use these commands to tell Git to use Linux style line endings.
