Confirmed 32.0a1 (2014-05-29), Win 7 x64

Comment 2

var campaign_list_totals = {};
campaign_list_totals[18] = 3,028;

console.log(campaign_list_totals[18]);

is supposed to return 3

On nightly it creates an error in console.

easiest way to reproduce problem:

type 3,08 in Firefox 27 > 8
type 3,08 in Nightly 32 > Error

This is a deliberate change, I believe, so I'm marking this invalid. The change was made in bug 957513.

Gijs, this is breaking some bank website (mine for example).
I cannot use Firefox any more to do some bank transfer.

Is that really expected?

I will move the discussion in the other bug.
