good program but not work about new virgen 66.0.3

Firefox was switching versions, so it would not download until I fixed that. Otherwise, great!

Well, it stopped working on my version, I hope this is due to a technical issue on the Web Browser's side and not to a drop of support.
To the folks suggesting to update Firefox, duh, not everyone can afford to do that. Thanks to the person who mentioned the workaround.
