what happens to firefox?

[François Patte]

Bonjour,

Today all my add-ons to firefox do not work!

Français language pack could not be verified for use in firefox and has
been disabled!

There a button "More information", unfortunately the link does not
work...: Page not found

Same problem with: facebook container, flash and video download,
ghostery, lilo, noscript, unpaywall, video downloadhelper

Since they have rewrite the code, firefox becomes more and more ugly! Why?

Thank you.
