Firefox Quantum Isn’t Just “Copying” Chrome: It’s Much More Powerful

Has anyone found quick and easy steps to remove the top tabs in lieu of the tree style sidebar? I don't want to prioritize that.

I like the web development tools that Firefox has to offer. I have also used it for a long time.

I've never locked myself to one browser or the other. I routinely use Edge, Explorer, Chrome, Firefox and occasionally Opera. I switched from Firefox to Chrome initially when it came out because it was lighter and faster. Firefox was a memory hog and bled RAM like crazy. Chrome was good. Then Chrome started doing that too. So, I go back and forth to whichever browser pisses me off the least at that moment in time. Right now, it's Firefox Quantum.
