Hello, download and install Firefox 52 ESR from here, which has your old layout and will be supported with security updates until May 2018: https://www.mozilla.org/en-US/firefox/organizations/all/

STOP FIXING THINGS THAT AREN"T BROKEN. I want my Classic Toolbar back. I want the Icons w/ text option back. I want NEW TAB + back. I want Scrapbook back. We aren't all a bunch of Silicon Valley or San Francisco techies.

Hi,

The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.

If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

I know that. I was just being rhetorical. The Mozilla feedback system seems worthless. Posting complaints to user forums sometimes elicits tips to resolve struggles.
