I can't reproduce. What site are you seeing this on?

Can you check the browser console for warnings or errors? https://developer.mozilla.org/en-US/docs/Tools/Browser_Toolbox

Can you try to get a regression range using mozregression (https://github.com/mozilla/mozregression)?

Thanks!

Confirmed also happens if I turn of all add-ons and restart.

Happening on Hootsuite.com, SFgate.com, actually all sites.

Dealing with mozregression is likely greater than my technical knowledge.

I'll check the browser console for warnings or error and post an update shortly.

Upon enabling the browser console, I see the errors and warnings for the page itself, followed by the message:

DebuggeeWouldRun: debuggee `resource://devtools/shared/base-loader.js:430' would run  builtin-modules.js:156:11

If I then click on the Control Center icon in the location bar, no messages get added to the console.

If I disable my user chrome CSS, the problem goes away. Investigating to determine which code is causing it and whether it constitutes a bug.

Comment 5

[Chas Belov]

I've traced it to the following code in my UserChrome.css. I likely put the code there by mistake -- it belongs in my UserContent.css. But the fact that it messes up the dialog appears to be a bug.

* {
    -ms-transform: none !important; 
    -webkit-transform: none !important; 
    transform: none !important;
}

Ok, sorry, but we don't support bugs caused by UserChrome.css :)

Thanks for reporting anyway!
