Does this not reproduce on Ubuntu 16.04 ? Does the issue reproduce with esr52 ? What version of gnome/x11 is this running?

This and some of the other linux-specific issues you filed smell like issues with the window manager / linux platform stuff, rather than frontend, even if that's where the problems manifest themselves...

Also, you've checked that ui.popup.disable_autohide in about:config is turned off, right?

On Ubuntu 16.04 this issue does not reproduce, neither on esr52.7.2 this not reproduced.
About version of gnome: GNOME Shell 3.12.2.
The ui.popup.disable_autohide is turned off, both on Ubuntu 14.04 and Ubuntu 16.04.

Can you find a Firefox regression window, then?

Based on this not reproducing on 16.04, I'm pretty sure this is a widget issue.

Right now I verified on Firefox 54, 55, 56  the issue does not reproduce, but on 57, 58 the issue is reproduce. May be this help you, tomorrow I send you the regression window.

What version of gtk3 and libxcb is the 14.04 machine running? Based on the pushlog, I expect this is related to bug 1397918.

I tried forcing a hack into my build to have the same effect as using an older libxcb would by disabling XShm, and I am still not able to reproduce this issue. At least, I don't directly see how XShm usage would factor into this offhand. Any ideas, Karl?

Also, Timea, if you set the layers.acceleration.force-enabled pref to true, does the problem go away?

Really, if I set layers.acceleration.force-enabled pref to true the issue does not reproduced on Ubuntu 14.04 x64. 
I done some tests and the issue from bug https://bugzilla.mozilla.org/show_bug.cgi?id=1446970 is also resolved with this pref set to true.

No real ideas, sorry, except that this does seem related to bug 1446970.
