The same here. Have you tried with FF add-ons that normally are the culprit for CPU hogging?

  Yeah, they're all on. Seems to be fine thus far, and there's an article about what they actually did to fix it, so I'm ready to say it's fixed. Only minor gripe is userChrome.css seems to not be used now.

    You need to enable it in about:config Set this option to true: toolkit.legacyUserProfileCustomizations.stylesheets
    • lordnacho 7y ago
      Was set to true already.

        Was it referring to browser.xul? There’s no XUL left, so you might need to change that to browser.xhtml.

      That's a slightly worrying precedent, they're calling the way to diaable certain bits of obnoxiousness (the header bar in Tree Style Tabs comes to mind) "legacy", which is usually a precursor to removal. Is there a new method available/forthcoming, or is this more control planned to be wrenched out of user's hands?
