You can remove prefs.js in the Firefox profile folder with Firefox closed. If you have extensions installed then you may want to keep a copy of extensions.webextensions.uuids and restore this pref afterward as the UUIDs are used to link the extension to its storage (indexedDB).

You can use the button in "Help -> More Troubleshooting Information" (about:support) to go to the current Firefox profile folder or use the about:profiles page (Root directory).
