      ionmarmalade This thing is a joke... A tragic fork of Firefox that restricts choices and breaks so many functions which are not recoverable with modification no matter how much you dig into the backend. Not to mention so many red flags as to how they themselves are using the program to syphon data on its users. Don't use it, unless you want them to sell your data.
