How to switch to a favored profile after downgrading
I'm using and old operating system on my computer, and the latest version of Firefox seems to overtax my graphics card, even with the most mundane websites and functions. So, I had to downgrade versions to the one just previous to today's update to even get here. However, it makes you create a new profile instead of using an existing one. Is there some way to get around this?

Things have changed since I last installed an older version. This article may help.
If you notice you have more content processes than in the past then Fission is probably enabled. Fission is about a new site isolation architecture in Firefox and you will see more Firefox processes running than before and when Fission is enabled you can no longer limit the number of content processes in Settings or via dom.ipc.processCount on the about:config page. You can check the current Fission state on the "Help -> More Troubleshooting Information" (about:support) page (search for Fission).
You can control Fission via fission.autostart on the about:config page, true to enable and false to turn it off.
- about:config => fission.autostart = false
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
