Please keep XSLT #2978

Operating System

All / Agnostic

Feature Description

Mozilla follows google in decomissioning xslt.

Please keep this feature to keep documents readable that require it.

Problem / Use Case

XSLT has been a w3c standard since 1999 and many documents rely on this mechanism to separate content from markup, not just css. Google dislikes that https://www.jwz.org/blog/2025/08/xslt/ and mozilla follows the money. Today the librewolf console said to me " XSLT will be removed from this web browser soon. See https://github.com/mozilla/standards-positions/issues/1287".

I urge you to please keep this important feature to separate (possibly immutable) content from markup and css and render it without code on the server, in.

I don't think it makes a lot of sense for LibreWolf to keep maintaining XSLT support independently from Firefox if they deprecate it.

LibreWolf focuses on security and privacy, not really on supporting old web standards.
This would add additional security concerns, and also fingerprinting aspects.

Also I want to make clear, this is not a question of "just not deleting it". Keeping something like this would mean actively maintaining it, adopting it to all coming changes and updates to the XML library and would basically mean completely rewriting it should Mozilla really decide to replace libexpat eventually. This is just completely unreasonable considering the minimal use XSLT has nowadays.

the manstream often has difficulties acknowledging the urge of minorities. We see such in many fields, especially when argued for diversity the quantity-argument is a slippery slope. Ultimately that can lead to a fascism of the majority.

I understand that librewolf doesn't want to maintain an engine, but you were my first stop as librewolf, being niche itself, may understand the diversity argument better than bigger organsations. Especially when those are funded by the bullies that put the axe on the root of this foundational internet standard.

There's a big amount of documents out there - many published raw xml data, rdf, feeds - that will cease to render for humans. If tools like browsers don't care about backward compatibility concerning w3c standards that are in for decades, we're in a dire situation.

Anyway, thanks for looking into it and bearing with me.
