It would be better if there was a way to address issues with uBO instead of hoping any problems that arise just go away on there own, Like how its just now decided to not work at all.

Good

Lo use por mucho tiempo, muy efectivo , pero ahora me aparece a todo lo ancho de la pantalla la leyenda que no esta actualizado, que lo deshabilite ,no lo he desabilitado ,trato de instalarlo y me dice que fallo la descarga que compruebe mi conexion. Saludos.

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.
