Hi there,

Recently, I noticed rendering issues on some sites using Firefox Nightly. Some sites impacted:
 - twitter.com
 - qwant.com
 - lemonde.fr

Attached an example of rendering issue (see the characters on the input field, which are collapsed to the left).

I investigated a bit, using mozregression, and it sounds like the culprit commit is this one:
https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=ed7d701658926c75bff77885d3258b2860d6dc3b&tochange=56f88b76d0fd6b0b207de727891610132e9a67a4

Cheers!
Florent

Also github, diaspora, and many others. I have to switch to Developer Edition until that's fixed, Nightly is not usable anymore unfortunately.

Same for me with some sites I can't live without:
* developer.mozilla.com for the javascript reference: see https://screenshots.firefox.com/jD52Lj2Lu9tDYAWS/developer.mozilla.org
* stackoverflow.com: https://screenshots.firefox.com/4XEh2UVrF9phzYnn/stackoverflow.com
* screenshots.firefox.com: https://screenshots.firefox.com/MWPk91POX1IV6M36/screenshots.firefox.com

Also running mozregression with the same result:

Hope this help!
