Firefox completely blank after copying profile after shiwtching OS

I have switched OS, from Windows 10 to Linux Mint, and wanted to copy the Firefox profile to the new OS. I tried using this guide: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I copied the xxxxxxxx.default-release folder, then switched OS to Linux Mint. After copying the files from the backup folder into the new folder, Firefox launches, but is completely blank. See the attached image. None of the buttons work, nor does the address bar or new folders. I also tried logging in to my Firefox account before copying the files, but that didn't work either.

Default Firefox works fine.

Copying a full profile folder is not a good idea, especially if different operating systems are involved. Some file store absolute file path that aren't compatible. Best is to copy only important data files and reinstall extensions and redo settings (prefs.js is one of those files as well as pkcs11.txt and extensions.json).
