The issue starts from Firefox 69 and persists on Firefox 70.0.1. It used to work properly on old versions. However, an error window prompts from version 69 saying my profile may be missing or cannot be accessed. Is there a particular reason why Firefox Portable have to access %AppData%\Mozilla and %LocalAppData%\Mozilla in order to start up? If those permissions are not necessarily needed, could you please fix this? Thank you!
