Firefox 53 conflicts with window manager theme

[Crati]

Firefox overrides the default window manager font color in some of its pop up dialog and buttons (included buttons rendered in webpages)
This leads to unreadable buttons text.

See the top of the attached Screenshot1.png for an example: The "Quit" "Save" "Save and Quit" text is white (should be black). Hovering over the "Do no ask next time" also turns that text white.

Problem appeared after update of firefox:amd64 (from 52.0.2+build1-0ubuntu0.14.04.1 to 53.0+build6-0ubuntu0.14.04.1).

Using the default Firefox theme or the other 2 new "compact" provided themes produces the same result.

On Xubuntu 14.04 with XFCE 4.10
In the snapshot above the XFCE theme is the standard "Adwaita" but the problem can be reproduced with other themes thought it is not present for example with the similar XFCE theme "Orion".

Changing the XFCE theme back and forth when firefox is open sometimes "fixes" the issue until Firefox is restarted.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. This bug was reported some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 14.04 (trusty) reached end-of-life on April 25,2019.

Does anyone still see a problem related to the one that was reported when using currently supported versions of Firefox and Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
