1437338 - Quantum browser garbles text on the Mozilla Addons Site

Status: RESOLVED DUPLICATE of bug 1446688

(Core :: Layout: Text and Fonts, defect)

Description

[Jeffery Small]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20171024165158

Steps to reproduce:

Visit https://addons.mozilla.org/en-US/firefox/ using Firefox ve3rsion 56 and 58.


Actual results:

Certain pages display properly in version 56 but are unreadable in Quantum version 58.  This is on a Xubuntu 17.10 system.  Below are links to four images demonstrating the problem.  Two are from version 56 and display properly.  Two are from version 58 and are completely garbles.  Option settings in both browser sessions are the same.

Note that not all pages on the site are mangled.  It appears isolated to search results and all specific add-on extension pages.  I have never seen this problem anywhere other than on the addons.mozilla.org site.

Expected results:

Pages should render properly.  The current situation is basically unusable.

This looks like the same issue as bug 1446688, dupe'ing forward to that report.
