Can't install h264ify

[Eluandar]

Pale Moon version: 27.2.1 (32-bit) (Linux)

Hey guys,
I can't install h264ify --> https://addons.mozilla.org/en-US/firefox/addon/h264ify/

It says: "h264ify could not be installed because it is a Jetpack/SDK extension which are not supported in Pale Moon 27.2.1"

I found this website (http://developer.palemoon.org/Add-ons:E ... ns/Jetpack) and I tried to change "package.json".
At first I downloaded the .zip file of h264ify for Firefox (https://github.com/erkserkserks/h264ify-firefox) and followed the instructions from the website
but unfortunately I can't load the extension because it always says: "This add-on could not be installed because it appears to be corrupt".

I am not a programmer and don't know how to handle this problem..
Hopefully there is someone who can help me..

You can try installing it via the "Moon Tester Tool" found here.

But be forewarned:

I take it that you renamed the .zip to .xpi ?
If so, you may be missing the install.rdf as it isn't included in the .zip

I already installed Moon Tester Tool but I don't really know how to use it.
I opened "Preferences" and "Select File" and chose the .xpi file I created but sadly nothing happens.

Install the original xpi file. Trying to install your altered one defeats the purpose of the Moon Tester Tool.

I tried to install the original xpi file by clicking on "Select File" and choosing the original .xpi file but still nothing happens.
Is it right to just rename .zip to .xpi ?

You don't need this add-on in Pale Moon, just make sure that "Enable MSE for WebM video" is unchecked under Options/Content. You can see actual codec used by YouTube player using "Stats for nerds" from video context menu. There should be avc1.4d401f of similar and not vp8/vp9.

Okay, thank you.
I would still like to have the "block 60fps" option. At least I could disable MSE.

Then use Moon Tester Tool to install xpi downloaded from AMO as suggested above. My brief test shows that h264ify loads fine using this way. Unfortunately I can't find any clip on YouTube that actually renders at 60fps in Pale Moon to verify if h264ify can prevent this.

Thank you, it works now.
I guess it was wrong to download h264ify from GitHub.

Thank you, it works now.

Could you share any example of clip where h264ify actually prevents from rendering at 60fps?

Thanks, it works there.

But I have to warn you that h264ify has potential security hole because it exposes its chrome script to the web without any wrappers. Fortunately it does so only for '*.youtube.com' and we can expect that no malicious scripts will be there, but anyway it's quite unsafe.

Perhaps this extension needs added to the blocklist...

Thank you, it works now.

I've added control of 60fps and WebM Video to HTML5 Media Tuner so you should consider it as safe replacement of h264ify that also works not only on YouTube.

Cool, thanks a lot!
