I have no idea WHAT they changed in quantum that makes it do this, but it's made the browser 4x slower rather than their advertised 2x faster.

So all the previous questions and solutions for this problem suggest it's addons and probably the users fault for the slowness of quantum. However I disagree Firefox 56, with all the same addons runs perfectly fine continuously with multiple tabs open, and my normal usage for extended periods of time, when switching tabs, minimizing, etc.

Firefox Quantum with all the same addons does not, after extended time periods it slows down extremely, when switching tabs, minimizing, etc. This includes the nightly, the beta, and the developer version, which I tried all three of because THEY had been suggested to fix the problem as well. I even attempted the about:memory "solution" which did absolutely nothing. I want a solution and/or a Fix, other than my current which is having uninstalled quantum completely and reverted to 56 version, I would LIKE quantum to work.
