Thanks for that @freaktechnik. Looks really good!
I tried it and the error console said, Error: Managed storage manifest not found.
I created the key with AutoIT using RegWrite and the key HKLM64. Is this enough to put it in the right place? I created the key with normal regwrite and key HKLM and that made no difference. Could it be a problem having both keys present? I thought Firefox just wouldn’t see the wrong one?
I put the path, ie C:\Users… Favourite\ where the file is - then I tried adding the full path… Nothing worked.
Thanks for your time.
