Firefox stable into Debian old stable, stable and testing ?

[Alex ARNAUD]

Dear Mozilla maintainers team,

On the latest Firefox ESR (52) we've noticed accessibility issues which 
impact both blind and visual-impaired users.

Why the Firefox package is blocked into Sid ? Could it be possible to 
have the Firefox package available on Buster and on the backports of 
Jessie or Stretch ?

Best regards.
