18.04 firefox - recent update broke xml

[stbub]

I have some files on my system that I browse with firefox.

file:///some/folder/data.xml

And data.xml is formatted using an xsl stylesheet.

This worked fine until this weekend. Now, I just see a big blob of unformatted text when I visit data.xml.

You might have an extension that is causing FF to only display the text nodes. Try disabling ALL your extensions and the opening an XML file.

you'll have to add the <Doctype> tag to your XML document.

If safe mode doesn't help try this extension https://addons.mozilla.org/en-US/fir...on/pretty-xml/

I use xsl stylesheet, and the headers of both the xml and xsl files are by-the-book. This has worked for a looooonnnnnngggg time. It started to be displayed incorrectly with the recent ubuntu updates. I don't have any extensions.

Would like to see the XML file your speaking of. If possible or safe to do so.
I see no problems on my end after i adapted to change.
You might not care, but offering anyway>>>Seamonkey also is a valuable browser for myself, and has not failed to open XML files.

A useful tool for XML validation is XMLCopyEditor. There is a version in Ubuntu Software Centre. Otherwise install the latest from web site.

I don't know xsl or xml, but the examples here https://www.w3schools.com/xml/tryxsl...file=cdcatalog work for me in Firefox Nightly 70.0a1 on Ubuntu 18.04.2 LTS when I edit the xml file.
