1244136 - userContent.css settings don't get used

Status: RESOLVED DUPLICATE of bug 1046166

(Core :: CSS Parsing and Computation, defect)

Description

[Lokesh Mandvekar]

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160126084715

Steps to reproduce:

My userContent.css looks like:

* {
    font: fixed !important;
    font-family: fixed !important;
    font-size: 10px !important;
}


Actual results:

Before the upgrade to 44.0, the 'Fixed' font used to get listed in my about:preferences#content. But it doesn't anymore.


Expected results:

Unless userContent.css isn't being used by firefox anymore, I should be able to see the 'Fixed' font in my fonts dropdown box.

Steps to reproduce:

I'm seeing issues with both userContent.css and userChrome.css after upgrade to 44.0.

Mozilla/5.0 (X11; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0

For instance, the following in userContent.css, a site w/ <pre> tags, this has no effect.  Using the ff debugger and altering/adding values under pre {} has no effect.  This same method on chrome works fine.

pre {
  white-space: pre-wrap !important;
  word-wrap: break-word !important;
  font-size: 8.0pt !important;
  font-family: "Liberation Mono" !important;
}

So I believe this is more than just userContent.css being broken but the honoring of any css for (at least) pre tags (at least font-family and font-size).

Actual results:

Before upgrade to 44.0, Liberation Mono for pre tags was honored and rendered correctly.  Currently, I cannot modify font-family or font-size either through direct css editing or use of userContent.css

Expected results:

userContent.css should be honored for the values specified above (font-family, font-size)

Works for me with:

Name 	Firefox
Version 	46.0.1
Build ID 	20160502172042
Update Channel 	release
User Agent 	Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0

However doesn't work for me with:

Name 	Firefox
Version 	48.0a2
Build ID 	20160520004020
Update Channel 	aurora
User Agent 	Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:48.0) Gecko/20100101 Firefox/48.0

with the default setting of "Enable multi-process Firefox Developer Edition" checked.  Unchecking it makes my "userContent.css" rules applied again.

The later issue appears Bug 1046166.  I'm not really sure what this issue is about – the original description mixes mentioning "userContent.css", and font options missing on the "Preferences" pages, which are mostly unrelated to me.
