Portable Firefox profile refresh and the upgrade to Windows 10

Firefox Portable was great when run locally on Windows 8.1 and previous. I finally "upgraded" to Windows 10 and now Firefox Portable has a ridiculous amount of "Not Responding" errors. It's almost unusable. I read that refreshing the profile might help in the transition between different windows versions and the link went here:
https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-s...
I tried that. Then Firefox restarts and shows up without some of my plugins. Then, when I shut it off and bring it back on again, it is back with all my old plugins and the same "Not Responding" freezes as well. I think it believes the "refresh" goes to the same exe as if I ran firefox from
PortableApps\FirefoxPortable\App\Firefox instead of just the FirefoxPortable.exe from PortableApps\FirefoxPortable
So what should I do? Do I even want a profile refresh to do this? I'd like to keep my history and bookmarks. Thanks for any help you can give!
