Please note that setting "gfx.xrender.enabled" to false cannot be a
permanent solution. It makes graphic rendering extremely sluggy over
network connections, where X client and server are not on the same
machine (and that's what X was designed for).

We deploy firefox in a client/server setup (Linux Terminal Server
Project, LTSP), for 800 users. Their firefox display is extremely slow
with xrender disabled. Scrolling down a page is a pain. Currently I need
to tell mu users: "You can have gray boxes in the address field, or you
can have slow scolling. What would you like?"

Setting "gfx.xrender.enabled" to false does *not fix* the issue, it just
hides it by the cost of losing other features.

Title:
  Adressbox Entries unreadable: Grey/Black Mask overlaying text

Status in “firefox” package in Ubuntu:
  Confirmed

Bug description:
  Labtop: Asus M2400, 512MB RAM, Pentium M "Banias" using "forcepae".
  OS: Xubuntu 14.04, all updates up to May 1, 2014.
  Application: Firefox 29, version "29.0+build1-0ubuntu0.14.04.2"

  Updated Firefox to Firefox 29 by automatic software update. Restarted
  firefox, now all the HTTP address entries in the address box are
  unreadable; it looks like they are masked by a black or grey/black
  mask. This independent of address and website.
