Description of problem:
The new Cinnamon theme (which got updated by default) makes it difficult to read the input and select box controls in Mozilla Firefox. The location bar is also hardly readable. This issue occurred soon after the last Cinnamon upgrade. See the two screenshots from Fedora 25.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Login to Fedora 25 with Cinnamon as the DE
2. Open Firefox
3. Click on the location bar
The controls are unreadable

You could try this extension
It adds an option to toggle text contrast.
That's partially https://bugzilla.mozilla.org/show_bug.cgi?id=1158076 but I don't think Cinamon actually uses "dark" theme variant.
The fix would be enabled e10s + mozbz#1158076 + set default white theme for content process.
And, of course, widget.allow-gtk-dark-theme should not be set to true.
Btw: With the new 52.0-6.fc25 build works around the bug in content process as described in comment #5, that's very nice. The urlbar is still barely readable because URLs are drawn in dark blue on dark gray. I've reported this separately, see bug #1435964.

Thanks, I hadn't thought to make that distinction.
