Hello,

I have a userChrome.css file that is the same across all my profiles (under /chrome folder). It is not working for Firefox Developer Edition when multi-process is activated (user profile dev-edition-default as seen in about:support). When disabling multi-process, it is working perfectly, but it is using the default profile. (but I want to have multi-process obvisouly ;) ) Again, the userChrome file is the same for both profiles.

Thanks, JB

I'll answer myself :)

The userChrome.css file is taken into account. However, it seems some of the browser DOM/chrome is different when using multi-process (ex: tabs and the behavior around class ".tabbrowser-tab"). So my rules where not working anymore.
