1014478 - "Facebook doesn't work" (Javascript deactivated without user interaction?)

Status: NEW

(Firefox :: Settings UI, defect)

Description

[David Teller [:Yoric] - still alive but not very active]

We have received a number of help requests from users who can't properly use a number of sites, including Facebook. It turns out that JS was deactivated on their machine, apparently without any action from them. Apparently, this happened during the upgrade to FF29.

We receive these requests every day from the contribute form. I haven't taken the time to investigate whether they are all related to JS being deactivated, but it's very worrying.

Maybe a bug in a specific extension or malware? I have seen some posts say CBSNews.com is not loaded on Firefox 29 but looks like it's a bug (or design) of Adblock Plus.

Or possibly a buggy anti-virus.
