In testing locking of preferences on the new in-content preferences, I noticed that when a button is disabled, a new "Do Not Enter" icon shows when hovering over disabled buttons. Please get rid of this. 1. It's unnecessary (the button is obviously disabled). 2. It looks cheesy. 3. It looks bad on 4K screens.

@Mike, We are(from Taipei office) recently reviewing the pref-related bugs. I am not seeing a "Do Not Enter" icon when hovering mouse over button disabled inside the preference page. Could you please provide the step to reproduce ? Thanks

The way to test this would be to lock the preference, for instane putting this in the scratch pad in the browser environment: Services.prefs.lockPref("pref.browser.homepage.disable_button.bookmark_page"); And checking the bookmark button on the main page. But as you point out, it does appear that they got rid of the do not enter cursor.
